    A. Introduction Title: The effect of reading Shakespeare on reaction time Research Question: Does reading a passage of Shakespeare decrease a person’s reaction time while completing a puzzle? One day in class‚ I was reading an interesting article about how people who read and are exposed to Shakespeare and Wordsworth and other renowned writers have better brain activity‚ attention spans‚ and can have more moments of beneficial self-reflection. In the article‚ scientists and psychologists at Liverpool

    The experiment did not contain any form of reaction mechanism since no chemical identity had been changed. The lab demonstrates the use of chemical molecular behavior to isolate a particular set of molecules. Caffeine had already existed in the leaf itself but needed to be separated from the other chemicals. Caffeine’s chemical structure is relatively similar to the nucleic acid purine in that they use nitrogen and is bicyclic but lacks an alkene‚ amine and an amide. Caffeine has a solubility of

    Enzymes Reactions to Changes in Substrate and Inhibitors Benjamin J. Mora Coronado University of Texas Rio Grande Valley at Edinburgh Abstract Purpose for the experiments was to test the enzymes in various scenarios and see how changing this would affect the rate of reaction. The enzyme source used in the experiments was Turnip Extract. Concentrations of Turnip extract for activity 1 where o.5ml‚ 1.0ml‚ and 2.0 ml as for the rest of the activities 2 Through 4 stayed at a consistent concentration

    The effect of temperature on the reaction rate: As the temperature increases it provides more kinetic energy to the molecules allowing them to move faster and with more energy the molecules can overcome the activation energy barrier and therefore the reaction occurs faster. 5. Since the proposed mechanism is a SN1 reaction the reaction got faster as the polarity increased. This is because SN1 reactions work best with polar protic solvents as they stabilize the carbocation. Therefore‚ as seen

    From this lab we can learn to observe physical properties of varying substances as well as to use chemical reactions to observe chemical observe the chemical properties of varying substances. In experiment #1‚ we were able to detect physical properties of the aluminum and copper sulfate simply by looking at the substances. We then combined the two substances to see if they would create a chemical reaction and test the chemical properties. After being combined‚ bubbles and gas were created and the

    Aim: The aim of this experiment is to investigate the process of Electrophoresis and successfully analyse DNA fragments. Hypothesis: That the experiment will show the visual representation of DNA proteins‚ and that the shorter the band the further is will travel. Background: Restriction enzymes are DNA-cutting enzymes found in bacteria‚ which cut DNA into smaller fragments. A restriction enzyme recognizes and cuts DNA only at a particular sequence of nucleotides‚ known as restriction sites

    anthracene from benzyltriphenylphosphonium chloride and 9-anthraldehyde through the reaction mechanism recognized as the Wittig Reaction. The Wittig Reaction allows the chemist to synthesize phosphoranes in the lab with relative ease. A more recent and inexpensive version of the reaction is the Wittig-Horner reaction (1). ABSTRACT Georg Wittig was a German chemist and Nobel Prize winner in 1979 for the Wittig reaction (1). He was born in Berlin‚ on June 16‚ 1897‚ and died August 26‚ 1987 (1). Wittig
