Reaction Rate of Hydrochloric Concentration

Reaction Rate of Hydrochloric ConcentrationHydrochloric IntensityThe purpose of the taste was to gather an understanding for the chemical answers, depending on the meanness. The value of reaction is the speed of the chemical reaction. This experiment was to justify if the submersion is high or low exit it affect the chemical reaction. Hydrochloric acid constitutes the majority of gastric acid, the human digestive fluid. In a complex act and at a large energetic burden, it is secreted by parietal cells (also known as oxyntic cells). These cells contain an extensive secretory mesh topology (c exclusivelyed canaliculi) from which the HCl is secreted into the lumen of the stomach. They atomic number 18 soften of the epithelial fundic glands (also known as oxyntic glands) in the stomach. The chemical compound hydrochloric acid is the aqueous (water-based) solution of hydrogen chloride gas (HCl). It is a strong acid, the major grammatical constituent of gastric acid and of wide industrial use. (LibreTexts. 2017). It is said from (chem4kids.com. 2017) if a reaction has a low rate, that means the molecules combine at a slower speed than a reaction with a high rate. The collision supposition was used to envisage the rate for a chemical transpose, collisions dont evermore have a chemical reaction. A chemical reaction needs to be equalized for it to have an effective collision. According to (Chemistry LibreTexts. 2017) A collision will be effective in producing chemical substitute only if the species brought together possess a certain minimum value of internal zippo, equal to the activation energy of the reaction. Furthermore, the colliding species must be oriented in a manner favorable to the necessary rearrangement of atoms and electrons.(askllTians. 2017)The experiment that was used, was all 5 interrogatory tubes filled with the identical come of sodium thiosulfate and adding to each diametric see tube different concentrations of hydrochloric acid and timing how fast the reaction rate is. This experiment was used to find come forward if you had different concentrations of hydrochloric acid would it affect the rate of reactions.Na2O3S2 + HCI = SO2Sodium thiosulfate +Hydrochloric acid = sulfur dioxideThe chemicals in this experiment were Hydrochloric acid and Sodium thiosulfate. Research has shown about hydrochloric acid it is a component found in the human digestive fluid from (Hydrochloric acid. 2017) it says that Hydrochloric acid constitutes the majority of gastric acid, the human digestive fluid. In a complex process and at a large energetic burden, it is secreted by parietal cells (also known as oxyntic cells). These cells contain an extensive secretory network (called canaliculi) from which the HCl is secreted into the lumen of the stomach. They are part of the epithelial fundic glands (also known as oxyntic glands) in the stomach. The chemical compound hydrochloric acid is the aqueous (water-based) solution of hydrog en chloride gas (HCl). It is a strong acid, the major component of gastric acid and of wide industrial use. If the human digestive fluid had a low concentration it would take longer to digest food. Concentration is the chroma of an element or substance in an experiment. Concentration is used in every solar day life in food, drinks and chemicals added to certain things.AimThe Aim for this experiment was if the concentration would affect the rate of reaction.Hypothesis The prediction for this experiment was that the reaction time will get faster and slower with each density of hydrochloric acid. Hydrochloric acid and sodium thiosulfate will mix together and create a yellow substance of self-coloured Sulphur. The controlled variable in this experiment was the concentration and the independent variable was the rate of reactions.5 assay tubes2 measuring cylinders (50ml each)5 different types of hydrochloric acid such as 0.2,0.5,1.0,1.5,2.0 (50ml each)1 sodium thiosulfate 75ml1 test t ube standGlovesGlassesLab coat3 stop watchesThis experiment started by the collection of the resources and safety equipment needed. Followed by the set up of the test tubes in the test tube rack and the measuring of 5ml of Sodium Thiosulfate for each of the test tubes. 15ml of Hydrochloric Acid of different concentrations ranged between 0.2 to 2.0 added to each test tube as soon as the hydrochloric acid is added the timer was stated and the experiment was observed till in that respect werent any more changes to the chemicals. When the chemicals first had a change the time from when the hydrochloric acid added to the change was record into a results table. Once there was no change to the chemicals, the times was also recorded. The experiment was done three times to possess sure there were the best results we could get and incase the results werent precise.

In the experiment for 0.2M the reaction occurred 51 seconds after combining sodium thiosulfate and hydrochloric acid together and the reaction stopped 6.45 legal proceeding after the combining. The hydrochloric acid with a concentration of 0.5M the reaction occurred 33 seconds after the combining and stopped 4.53 minutes after. 1M was 25 seconds and stopped at 2.42 minutes after, 1.5M was 18 seconds and stopped after 2.25 minutes after and finally 2M the reaction started at 58 seconds after it was combined and it stopped 3.37 minutes after the combining. Although all the concentrations of hydrochloric acid, the clear liquid it once was changed to a creamy white.In experiment 2, it started the same way as experiment 1. Although some of the results were different to experiment 1. O.2M it started at 51 seconds and stopped at 6.45 minutes after, it was the same as in experiment 1. The chemical reaction started at 33 second s and it stopped 4.53 minutes whereas 1M started at 26 seconds and it stilled at 2.42 minutes after it was added. 1.5M was started at 18 seconds whereas 2M started at 58 seconds but 1.5M stopped at 2.25 minutes and 2M stopped at 3.3minutes. However, all the concentrations in the end change to the same color in experiment 1.Experiment 3, just like all the other experiment it was started the same way with the clear mixed chemicals however, the chemical reaction happened when the sodium thiosulfate was being measured because it was accidently measured in the hydrochloric acid measuring cylinder so that effected the results for this experiment, so it was measured when it got to a darker shade of creamy white. 0.2M was affected 41 seconds after and it stopped 3.15 minutes after. 0.5 changed 38 seconds after and it stopped at 2.36 minutes. 1M was the one that was most effected when measuring the sodium thiosulfate occurred it was recorded in the results that it started at 0.06 seconds and stopped at 1.49 minutes. 1.5M started at 45 seconds and finished 1.27 minutes after finally 2M started at 10 seconds and stopped 2.11 minutes.The Average, when the recording was contingency there wasnt someone all the time watching the experiment so it may not be quite high-fidelity. The bonnie for 0.2M was 5.35 minutes, 0.5M was 3.81 minutes, 1M was 4.58 minutes, 1.5M was 4.02 minutes and finally 2M was 2.47 minutes. This average was only recorded by when the chemical changed stopped.The research collected helped understand what was going on with the experiment it was known if it had a low concentration is would go slower and it would go faster if it had a high concentration. The Hypothesis was supported it did get faster and slower with each density of hydrochloric acid. Although it didnt create a solid yellow substance, the experiment only created a liquid substance. This experiment has created a understanding of what would happen if the human digestive fluid has a much highe r(prenominal) concentration it would help digest quicker but it would also eat the lining of your stomach.EvaluationThis experiment worked well but there were many mistakes that occurred such as the results were not recorded properly because you needed to keep an eye on the experiment at all times to get the most accurate answer. The other mistake was with the measuring cylinders needed to make sure that this experiment used one for sodium thiosulfate and a another for hydrochloric acid otherwise it will be an inaccurate answer because the chemicals will already mix when your measuring how much you will needwith one of the chemicals. To improve this experiment, it would have been better if one soulfulness is always watching the tests so this experiment would have made the results more accurate and if the measuring cylinders were easier to tell apart so there was a clear distinction of which on was used for that certain chemical.Conclusion In conclusion, the experiment was used to h ave a better understanding of chemical reactions depending of the concentration. The collision theory was used to rate the chemical change, hydrochloric acid and sodium thiosulfate make a yellow liquid substance. Concentration is also used every single day without most peoples knowledge. The concentration did effect the reaction rate because it either had a high or low reaction rate. The hypothesis was supported except for the concentration of 2M more information was needed to understand why.BibliographyChemistry LibreTexts. (2017).

Does Violence in the Media Contribute to Violent Children?

Does Violence in the Media Contribute to Violent Children?Alaina DavisWhile well-nigh people may disagree that barbarian media contributes to convulsive fryren, the fact remains that personnel is now part of our everyday world. M each tragedies, from the Gulf War to the loss of the World Trade Center Towers were televised nightly or raze 24 hours a day on some news channels. I am not suggesting boorren be deprived of the knowledge that there is madness in our world, rather I would suggest that children must be supervised for such programming, because children toiletnot always tell the exit between fact and fantasy.In this paper, we forget look at three specifically violent events and the feelings of children who thinkinged the events on video recording, or were within close proximity to the violence and support uped it televised as well. I do not personally believe that tv set has the exclusive power to create a violent child however I do believe that it can be an int egral part of a storm of events that can cooperate to create a violent child.There is an amazing array of numbers and facts surrounding television alone, regardless of programming and the ages of the children who watch unsupervised. Fremont (2007), states that there is an average of three televisions in 41% of American homes.Children from ages 2-7 watch television unsupervised and alone 81% of the clip. In this analogous age group, 33% select televisions in their own bedrooms. I personally feel that this is far too much television for children of this age to watch television so much with no adult supervision. It is unadorned that television has indeed be acclaim the new babysitter. An early(a) statistic from Fremont (2007) is that children watch televised news 65% of the time as compared to 44% who read news paper. Television, and images in general tend to generate a much visceral reaction than reading printed text does. For grammatical case, I can write a text besides repor t about the violence surrounding the Twin Towers Attacks on September 11, 2001, and it allow no doubt resurrect up some reaction, in part because we all had such a large nitty-gritty of television exposure to the event. However, even at that, reading a text only report, will not elicit the same visceral response as showing pictures will, and that response will heighten with each sweetener to the report. Videography, with a narrator and actual live footage of the event, elicits the strongest reaction to any event, good or bad. However, in our society, violence seems to elicit the strongest responses and the most interest. This is true of not only our news broadcasts, but of television shows, movies and video games.A few to a greater extent facts, which will become more(prenominal)(prenominal) clear as we relate them to specific eventsless(prenominal) than 50% of children display feelings of anger, depression, or sadness after watching the news (Fremont, 2007). Bushman (2007), sta tes that young children are more likely to imitate what they see on television. Considering the amount of the age 2-7 group of children that are allowed unsupervised viewing and the psychological processing of that age group, it is easy to see why they would imitate what they see without reasoning for consequence. smiler Hamilton-Giachritsis (2007). have shown a correlation between homes that are violent in nature, children who watch large amounts of televisions in these violent homes, and juvenile delinquency in their young years.There are many forms of violence available on television, as entertainment, education, or in conjunction with television and the internet, such as on violent playing period. As a starting place, we are going to briefly visit three theme tragedies, in order of happening because television coverage change magnitude with each tragedy. As coverage increased, so did the amount of televisions available to view it on, as well as the time of the coverage.The first national tragedy is the competition accident, resulting in the destruction of the space capsule, as well as everyone on board, including a civilian pistillate drillteacher. Compared to the next two national tragedies, the Challenger have little airplay of the accident scene that was aired on the national news of the takeoff, and the very sudden violent explosion of the capsule. As an adult, I briefly think back the news coverage about the accident, and I remember that coverage was short lived. I had a 3-year-old daughter at the time, but she was never allowed to watch television unsupervised as a child, and she did not watch televised news. However, in a small nurture done at the time of 153 children from Concord, NH, and Porterville, CA, there was no initial reaction difference between the two coasts (Fremont, 2007). There was an increase in post-traumatic stress disorder symptoms in East coast children, as opposed to the westbound coast children (Fremont, 2007).Fremo nt (2007). did not state the ages of the children involved in the study, but we know that children under eight are generally less able to tell the difference between fantasy and historicality. That is why children from 2-7 still believe in the Tooth Fairy, the Easter Bunny, and the monsters under the bed. Because they do not always process these events as real, and therefore not as horrific as older children, juveniles do and adults do, if they develop symptoms at all, it is likely as an emotional cue that this is how we are supposed to act in response to such a tragedy.The Oklahoma City Bombing was a personal event because I live in Oklahoma. There was more national coverage on the news, and for a longer period of time than with the Challenger accident. Neighbors talked about it for longer periods, even after the news stopped covering it.In another study, seven weeks after the event, 3000 children of middle and high school age were surveyed. Freemont (2007). noted that those who w ere bereaved through involvement, directly, or indirectly, were more likely to report symptoms than those who were not so closely involved with the incident. However, it is also important to note that the Murrah Building Bombings television exposure did lead to trauma related symptoms for more than 2 years past the actual event date (Fremont, 2007). Given the additional coverage time and duration of this incident, which occurred nine years after Challenger, it is obvious that violent television broadcasts do have an effect on children.Our final national tragedy is the day simply known now as 9/11. On September 11, 2001, hijacked jets being flown into each of its twin towers attacked the World Trade Center in New York (Manhattan). Television and radio coverage started before anyone even knew what was happening. First reports were only for a plane of undetermined size having crashed into the North Tower. Before it was all over, a third plane would have crashed into the Pentagon, and a tail would be diverted by extremely brave passengers into crashing into a farm field, rather than its target, which was assumed to the be the White House. The second crash into the Twin Towers was televised in live time, as it happened. People all over America and the world watched as those towers burned, smoke rolling from them, and people jumping amid the papers blowing off the undecided upper floors. Finally the entire crash of first one tower and then the other, all taking place on live television, in real time. This was horrific for a number of reasons the amount of people initially dead and missing, relatives across the country, and around the world were uncertain if they were in shock for the nation, grieving personally, or both. Television coverage went on and on, replaying the horrific images repeatedly on 24-hour broadcasts. Other news was reported while these images played in the background on some channels.Fremont (2007). reports in a study done of grade 4-12 aged chi ldren in the New York City School system reported an increase of 8.5% of PTSD symptoms following this tragedy. A supporting study confirmed that there were symptoms of PTSD (particularly anxiety) in children who had excessive television exposure to this event even as far outside(a) as the West Coast. The difference was that children at a distance suffered more anxiety over whether a loved one was injured or killed children on the East Coast suffered grief for those injured or killed in the attacks, as well as anxiety about their futures, and the impact this tragedy would have on their future (Wilson, A.C., Lengua, L.J., Meltzoff, A.N., Smith, K.A., 2010). Again, parental trances did have some bearing on how much stress a child suffered from this event. According to Wilson, A.C. et.al. (2010), children from single parent homes displayed more symptoms than homes where both parents were present. Another important point is that children who had parents who showed positive emotional r esponses following the 9/11 attacks, such as crying in grief were much more likely to seek out or ask for help with their feelings over the attack.We do see that violence has an effect on children, at least, on school age children. The three events we have discussed so far were real incidents, happening to real people, and being broadcast in real time on television. tho what effect does interactive violent media have on our children?The more attractive video games, to the age 8 and above group, are violent. Whether it is fantasy violence, such as Angry Birds, or animated human violence, such as Halo, or other war programs, these are the games that are advertised heavily, promoted as great gifts and come with a great amount of attached peer pressure to play these games. Bushman (2007). noticed that females had become increasingly violent as the media and society supports the tough, aggressive female character. Traditionally, females are exposed to violent video games later than male s, because they are not drawn to watch violent sporting events such as football and hockey (Bushman (2007).While news broadcasts of national tragedies obviously cause symptoms of stress and anxiety in older children, what about younger children? For younger children, violence seems to really have not much of an effect. We read Grimms stories to our toddlers it rarely gives them cause for stress, or anxiety. They are unlikely to display infantile reactions to stress from being read Hansel and Gretel, for example by sucking their thumb, or wetting the bed after hearing the story. Yet, this story is violent two children, left in the woods by their parent, put by a witch, who attempts to murder them. For children under the age of eight, most research seems to agree that televised violence, viewing video games, or even hearing stories such as Grimms Fairy Tales, have little to no effect.Kotler and Calvert (n.d.), support that younger children tend to use instrumental aggression aggress ion that is used in the call for of controlling or obtaining an object. Therefore, an average preschooler may strike another child in the quest to get a toy, for example. However, by the time the child enters the first grade, at age 6 or 7, they are starting to use words to fight, rather than physical violence, and may even reject physically aggressive school peers.Supporting my theory that violent media alone does not make a violent child, Kotler and Calvert (n.d.) assert that by the time a child is a pre-adolescent or adolescent, they understand that the quest of revenge, such as is displayed in many video games, is the wrong moral path. However, those children without strong social ties, and who tend to be isolated, endorse violent revenge (Kotler Calvert, n.d.). Further support to the fact that while violent media does contribute, but is not the sole reason for violent children, is a study conducted by Johnson, et.al.,over 17 years in a community of 707 individuals. In each ca se, there was significant support for those who watched violent television in early adolescence and subsequent aggressive acts in adolescence and young adulthood.Males outweighed females in the same age brackets, but routinely, those who watched television for more than 3 hours per day, regardless of the violent content, were 14.6% more likely, overall to engage in physical assault or fighting that would result in injury at age 16 or 22. For those same ages and the same amount of television, 12.7% were likely to engage in any aggressive act on another person. These statistics were true whether or not the adolescent had any of the other risk indicators present for aggressive behavior, or a history of aggressive behavior (Johnson, Cohen, Smailes, Kasen, Brook, 2005).I have to admit that when I chose this topic, I was not on the side of violent television causing violent children, or even being a major contributor. However, the facts are irrefutable children who view violence after th e age of 8, particularly when the situation of the childrens lives are coupled with a low income home that may be violent in nature, is more likely to become violent, or at least accept violent behavior in their adolescent and young adult years. Of course, contributing to my own view is the fact that when I was a child, most homes did not even own one television, programming was rarely violent in legal injury of todays acceptable programming, and we were generally limited to an hour of prime time, supervised viewing with the entire family between dinner and bedtime.With the research conducted however, it is not possible to deny that younger children (under age 8) are less able to process and disseminate information, because they simply have no frame of reference for what is acceptable and unacceptable in terms of violence. I do not believe, however, that children of this age should watch television unsupervised, simply because they are learning to reference what they see. Without a n adult present to help them interpret what they see, in later years, they will not have a frame of reference to fall back on.Society will never be perfect we will always have those children, as well as adults who suffer rejection, bullying, and other forms of violence simply because they are different. However, I honestly believe if we all take the advice of the researchers, and supervise our young children, rather than forbid violence in all forms, we will raise children who will be able to survive those rejections, bullyings and other hurts of growing up without becoming violent. On the other hand, limiting and supervising the viewing and use of violent media in the home may help those children who suffer from disabilities that already promote low empathy (such as Autism Spectrum Disorders like Aspergers) to understand that violence solves nothing.Finally, parents must accept primary responsibility for their children, their childrens viewing and gaming habits, and ensure that the ir friends have parents who are involved and engaged with their children as well. Fremont (2007). recommends that the age group under eight not view television or other media without supervision. She also recommends that the adults in a childs life be prepared to help them with responsible interpretation of any violent content that is viewed.ReferencesBrowne, K.D., Hamilton-Giachritsis, C.

Twentieth Century History of South Africa Essay -- African History

The twentieth century history of southwestward Africa contains many struggles and obstacles as its people worked towards creating a more unified country. Modern human beings have inhabited South Africa for more than 100,000 years and a great deal of colonisation has occurred within the last 300 years. During the late 18th century, 90 Dutchmen landed on the Cape of Good Hope as part of the Dutch east India Company, representing the first permanent settlers of South Africa. In 1652, they were instructed to build a fort and to start growing crops to aid the ships travelling along the Eastern trade route. 5 short years later, approximately 250 snow-covered men occupied the area, bringing with them slaves to aid in growing more crops. Their farmland began to expand, and the native South Africans annoying of expanding Dutch colonization was becoming a reality. Immigration was encouraged in the 19th century, and the independent farmers called trekboers started to expand their far mland to the north and east. Slaves brought into South Africa by the white colonists created a mixed race group known as colored, creating a mixture of race and culture seen today in South Africa. inseparable South Africans were losing ground to this expanding Dutch colony and their slaves (Southafrica.info, 2012, pg. 1). According to the U.S. State Department (2012), African farmers known as the Boers began to migrate into South Africa in 1836. These colonists fled to Africa partly to get away British rule and due to the recent abolition of slavery in Britain. This created strife and conflict with the native South Africans, the most formidable being the Zulus. The attractor of the Zulus, Shaka, reigned over the area from 1787 to 1828.

The Nature of Humanity in the Work of Sherwood Anderson Essay -- Human

The Nature of Humanity in the Work of Sherwood AndersonA common staple of horror storiesin film and on the scalawagis the scene of the frightened and indignant villagers chasing the monster who has been terrorizing the townsfolk. In Sherwood Andersons Hands, the protagonist, Adolph Myers (Wing Biddlebaum) is a well-intentioned individual whose actions the people around him contort so that he becomes more(prenominal) fiend than friend. In Wing Biddlebaum, the very aspects of his character that make him human are those that society distorts to make him into a maladapted monster first, the mystery that surrounds him causes the townspeople to misconstrue him second, because of the accusations of his pedophilic homosexuality stemming from this misunderstanding, they demonized him into a pariah and, third, the guilt that the mob forces him to feel ultimately confines him to his own prison of anguish. Approaching the story from this perspective demonstrates that Wings destiny is al cl osely beyond his control, a destiny significantly manufactured by his societys judgments. Wing is an extremely intricate person however, most of the people among whom he lived in Pennsylvania before his current residence in Ohio failed to recognize this, as do his fellow citizens in the town of Winesburg. Anderson describes him as one of those rare, little-understood men who rule by a power so gentle that it passes as a lovable weakness (13).

Fantasy and Reality in D.H. Hwang’s, M. Butterfly Essay example -- D.H

Fantasy and Reality in D.H. Hwangs, M. Butterfly A person may search their whole life for love. round are lucky enough to find the perfect someone, and some are not. The ones who are not as lucky can sometimes create their own idea of their ideal partner, but never actually find them. In D.H. Hwangs play M. Butterfly, a existence by the surname of Gallimard creates his own idea of the perfect partner. He falls in love with a woman by the name of Song, who turns out to be not what he expected. Song is actuality a Chinese spy disguised as a woman. Hwang illustrates in the play M. Butterfly, people are not always who they perceive to be. by means of Gallimards love for song, his portrayal for the East and West, and Gallimards obsession with power, M. Butterfly, demonstrates the different views of power and weakness that symbolized masculinity and femininity. Gallimard does not find out that Song is indeed a man until the end of the play. By this time, Gallimard is already co mpletely in love with Song, yet he knows that his love is too good to be true. In Gallimards mind, he creates this range of a function of what he believes to be his perfect woman. Song portrays this image in Gallimards mind. He declares that he was once loved, and was loved by very simply, the Perfect Woman (77). In spite of knowing that Song is actually a man, Gallimard continues to fantasize about his once perfect woman. After learning that Song is a man, Song covers Gallimards eyes with one hand. With th...

Addition Of Vectors Essay -- essays research papers

I. IntroductionA vector is an arrow whose length represents the magnitude of a quantity and whose direction represents the direction of the quantity. Vectors atomic number 18 efficacious in combining velocities that are non parallel. The sum of two or more comp wizardnt vectors is called a resultant.When the vectors are not at adept angles to individually other, the resultant is found by constructing a parallelogram. The parallelogram is constructed with the two vectors as sides. The resultant of the parallelogram is its diagonal.Equilibrant vector on the other hand, is a single vector that would poise the skipper vectors taken together.An experiment was conducted to determine the difference between using graphical, analytical and experimental method in getting the resultant. A force table, heaviness holders, a set of slotted masses (200g and 249g), ruler, protractor, spring scale and triple beam balance were used. Each group has its own assigned mass and forces as wellhead as a force table. Weight hangers were attached to two strings tied to the center ring of the force table, where two slotted masses, one 200g and the other 249g were hung fit to their stipulate directions.

The 2008 Beijing Olympics: China Pushes Towards Modernization Essays

The 2008 Beijing Olympics China Pushes Towards ModernizationThe Olympics are always use as a way for the host city to put on a display of its culture and show the world its myriad social and sparing triumphs. The host country can, in just a couple weeks, show the world what a wonderful place it is. The Olympics have in the past been fit to prompt a world awareness of the host country and create a lingering legacy. Beijing will attempt to do all these things, hardly the stakes will be much higher. China is the most populous country in the world and at the center of many global issues. With its improver to the World Trade Organization (WTO) in 2001, China do a big step in accepting the challenge from other world powers to on the loose(p) up its merchandises, address human rights, and transform itself from a developing country to a modern world power. With its official Olympic Action Plan, Beijing has made it its mission to directly address these issues with its emphasis on the concepts of Green Olympics, High-tech Olympics, and Peoples Olympics. Indeed, Beijing is maneuvering itself into position to use its fifteen minutes at the center of the world stage to put on quite a show. At the same time, Beijing can use the opportunity of putting on the Games to better its economic position in the world. Chinas economic growth has been fuddled due to foreign investment in Chinese manufacturing. The skip will continue. Foreign investment for the Games will stimulate growth while Chinese manufacturers will be able to exploit the new export market for Olympic goods. At the same time, China hopes to boost its position in making its own high tech developments to go along with its already strong manufacturing sector.
