Purpose: This experiment is used to perform a series of synthesis reactions that convert aluminum foil to alum. Alum is used in cooking‚ to treat wastewater‚ and is used in common deodorant. In this lab a series of four reactions will occur to yield alum. Calculations: Aluminum foil: 0.5035 grams Alum & Watch Glass: 21.7691 grams Watch Glass: 15.1560 grams Alum: 6.6131 gram Theoretical Yield of Alum: 2Al(s) + 2KOH(aq) + 4H2SO4 + 22H20 -> 3H2(g) + 2KAl(SO4)2 + 12H2O(s) 0.5035gAl

Multistep Synthesis of Tetraphenylcyclopentadienone In this laboratory experiment a synthesis was performed through several separate steps. The purpose of the experiment was to synthesize tetraphenylcyclopentadienone from benzaldehyde and to run reactions on carbonyl containing compounds. There was a total of three steps that led up to the synthesis of the final product‚ tetraphenylcyclopentadienone. The first step of the experiment was the condensation of benzaldehyde to yield

Zimbardo Prison Experiments The Zimbardo prison experiment was set up to investigate the problem of what the psychological effects for normal people result from being a guard or inmate‚ and in a broader sense are normal people capable of being ‘evil.’ The research question being asked was‚ “How would normal people react to being in a simulated prison environment? In Zimbardo’s own words‚ "Suppose you had only kids who were normally healthy‚ psychologically and physically‚ and they knew they would

and therefore the crude solid must be purified. This purified product is what is later put into the analgesic. In this experiment‚ the procedures that are important are vacuum filtration and recrystallization which are both used to obtain the Acetaminophen product. When collecting products‚ it is important to know how much product is left and what is lost through the experiment. To do this‚ the balanced equation will be looked at and then the theoretical yield will be calculated. In order to calculate

The Stanford Experiment of the 1970’s was a test of human nature conducted by the Stanford Psychology Department. A total of 24 students with no criminal or physiological health background were selected to be either guards or prisoners. The experiment was planned to last two weeks‚ but after only six days it had to be stopped for it was becoming too much to handle for everyone involved. The guards had disobeyed their instructions and began to physically abuse the prisoners‚ while the prisoners began

gratification is associated with resisting a smaller but more immediate reward in order to receive a larger or more enduring reward later. In a few words‚ replace the small rewards with a bigger but including some disciplines and sacrifice. The original experiment used children age three to seven as subjects but in different groups. The children were led into a room; empty of distractions‚ with a marshmallow was placed on a table‚ by a chair. The children could eat the marshmallow‚ the researchers said

1. The general idea of the article is about a mock prison experiment conducted by Doctor Zimbardo. The research was to identify the psychological causes of aggression and violence‚ and to observe the variables that promoted such behaviour in prison. He did this by using two groups of people that were randomly assigned as either a prisoner or a prison guard. The hypothesis that is focused upon to provide an explanation to the conditions in prisons is the dispositional hypothesis. The dispositional

In 1971‚ in the basement of the psychology department of Stanford University‚ Northern California a mock prison was created. Psychologist Philip Zimbardo placed an advert in the Palo Alto Times newspaper‚ asking for volunteers to study the psychological effects of prison life (Zimbardo‚ 1971). Only seeking male college students‚ over 70 volunteers applied. All of which went through strict screening tests to eliminate volunteers with psychological problems‚ physical and mental illnesses‚ also a history

create an experiment that looked at the impact of becoming a prisoner or a prison guard. The experiment was to test human behavior when one’s role had been altered into authoritative one. Still powerful after all these years the experiment was the most powerful and popular experiment of all time (O’Toole‚ K). Researches set up a mock prison in the basement of Stanford University building. There were the 24 students out of 70 volunteers chosen to play the roles of the prisoners or prison guards. The

Philip Zimbardo’s prison experiment was also about cognitive dissonance; whether or not people would be obedient to authority. The Stanford Prison Experiment took place in 1971 and was to last 2 weeks; the study only lasted 6 days because some participants were experiencing severe anxiety or‚ like one participant‚ went on a hunger strike. Participants responded to an ad offering money if they signed up for a prison research experiment. Some participants were made guards‚ others were made prisoners
