Diels alder reaction

Result: For the Diels-Alder reaction: Maleic acid is 0.002 mol 2,3-dimethyl-1,3-butadiene is 0.002 mol The theoretical yield is 0.36g Cycloaddition product is 0.358g (maybe it was not completely dry when I weighted.) The % yield of Diels-Alder reaction is 99.4% For the hydrolysis: The theoretical yield of hydrolysis is 0.396g The experimental product yield is…

2.03 Cell Membranes and Homeostasis

Objective(s): The reason for this experiment is to see how starch and iodine affect each other and how a plastic bag works similar to a membrane in certain situations. Introduction: I know prior to doing this experiment that iodine mixed with starch creates a dark color and that most objects, organic and inorganic, naturally experience…

Uniform Rectilinear Motion

Abstract The purpose of this experiment, was to prove the concept of the uniform linear motion by using an air track. With this, we demonstrated the impulse and change in momentum, the conservation of energy and the linear motion. We basically learnt to calculate the distance/time, acceleration/time, and velocity/time and graph it. The air track…

A variation of the Stroop effect

Abstract The effects of completing a task which requires the use of both automatic and controlled processes was investigated through a two-process experiment designed around a variation of the Stroop effect. Previous research found that, when performing certain tasks, response time is longer when an automatic process conflicts with a controlled process, in this instance…

Electrophilic Aromatic Substitution

The experiment focuses on finding out what kind of activating effects that four different substituents will have on an aromatic benzene ring. The substituents being tested are aniline, anisole, acetamide (acetanilide), and phenol. All four of these groups are either para or ortho activating. Bromination is the reaction that will be carried out. The melting…

Wild animals in captivity

Wild animals are kept in captivity for a variety of reasons and in a range of environments, including zoos and circuses, scientific laboratories and also as pets at home. Caring for a captive animal takes time, money and knowledge to provide everything the animal needs, such as food, water and the correct environment, to prevent…

Organic Chemistry Experiment 4 – Recrystallization

INTRODUCTION Recrystallization is the primary method for purifying solid organic compounds. Compounds obtained from natural sources or from reaction mixtures almost always contain impurities. The impurities may include some combination of insoluble, soluble, and colored impurities. To obtain a pure compound, these impurities must be removed. Each is removed in a separate step in the…

Science Essay

Science to me is everything that surrounds us. It’s to discover information about this world we live in, study this information, and use it however we will; a process that has started long, long ago, and will continue in generations to come. Everything in our world that we use somehow or someway was made by…

Contesting the “nature” of Conformity: What Milgram and Zimbardo’s Studies Really Show.

From the 1960’s to the 1970’s understanding of the psychology of tyranny is dominated by classical studies. Two such studies include Zimbardo’s Stanford Prison Experiment and Milgram’s research on obedience to authority. This research has revealed that many times people obey inactively and unthinkably to both roles that authorities offer as well as orders given…
