have souls. Why we feel bad‚ we no have no souls? We want to be free very much.” This is a part of a letter that Kale‚ an African of the Mendi tribe‚ wrote to John Quincy Adams. Kale‚ coming from nothing‚ learned enough English while abroad then Amistad Slave Ship. Africans of the Mendi tribe struggled to regain freedom after Spanish abuse. Sometime in January of 1839‚ hundreds of Africans were captured near Sierra Leon. The Africans were beaten and blindfolded. They were then boarded onto a Portuguese

Dave Dilebre Composition I Professor gould February 18‚ 2014 Review of “Amistad” by Sally Hadden summary Amistad begins with the event that made the ships history different from other slave ships. Cinque also known as Sengbe feed himself and his fellow slaves. They overthrew the ships crew killing all the spanish sailors but two in order to sail back to africa. The two men that were left of the crew managed to trick their new found captors and sail to new york. The initial trial

La Amistad movie a movie released in 1997 was a true movie story based on slavery life it took about how slavery was managed and about the slaves of La Amistad ship‚ La Amistad ship is a ship which carried slaves from other countries to the U.S. The historical setting is in Connecticut‚ a place in the U.S. The event took place in the 1800s. At the beginning of the movie Cinque the leader of a tribe was in LA Amistad ship then he managed to scaped from the spanish crewmen ‚ slaves force 2 spanish

Abstract: Enzymes are part of human’s everyday lives and improve the quality of living. Enzymes decrease activation energy which pertains to how much energy is needed for chemical reactions to take place. Enzymes also known as catalysts is one of the main factors in producing energy in individual’s bodies. The experiment conducted was to test how different temperatures effected the catabolizing of fungal and bacterial amylase‚ as well as the optimal temperature needed for the enzyme to correlate

Ronak Parikh U30682934 Experiment 2: Diels-Alder Reaction: Synthesis of cis-Norbornene-5‚6-endo-dicaroboxylic anhydride Introduction: The main goal of this experiment is to perform a Diels-Alder reaction between 2‚3-dimethyl-1‚3-butadiene and maleic anhydride‚ identify the product and hydrolyze to form the dicarboxylic acid. Diels alder reactions are classified as pericyclic reaction‚ which is a reaction which involves a cyclic rearrangement of bonding electrons‚ which means

Abstract:The Wittig Reaction is a nucleophilic addition in which an alkene is formed as a product. Both the E and Z isomers of the alkene result. Substituents on the aromatic aldehyde affect the E/Z ratio of products that form. In this experiment‚ a nitro group was used as the substituent in the ortho‚ meta and para positions‚ with benzaldehyde as the control. Each of the four aldehydes reacted with (carbethoxymethylene) triphenylphosphorane to produce ethyl cinnamate‚ ethyl-3-(2-nitrophenyl)acrylate

An Investigation into the Factors Affecting the Rate of the Reaction between Calcium Carbonate and Hydrochloric Acid A chemical reaction is the process by which atoms or groups of atoms are redistributed‚ resulting in a change in the molecular composition of substances. The reaction rate is how quickly a reaction occurs and this can be affected by four different factors: ¡¤ changing the surface area of any solids involved ¡¤ changing the concentration of reactants in solution ¡¤ changing the temperature

Write down the aim of your Investigation. To investigate the effects of change in concentration on the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid. Briefly describe your Preliminary Experiment and include your results. Explain how these results have helped you plan your main experiment (p8b). An increase in concentration will lead to an increase in the rate of reaction because there will be a greater number of particles per unit/cm3. The particles will be closer together and

SN2 Reactions: Nucleophilic Substitution at Saturated Carbon Date of Experiment: February 6‚ 2008 Objective: The objective of this laboratory experiment is to study both SN1 and SN2 reactions. The first part of the lab focuses on synthesizing 1-bromobutane from 1-butanol by using an SN2 mechanism. The obtained product will then be analyzed using infrared spectroscopy and refractive index. The second part of the lab concentrates on how different factors influence the rate of SN1 reactions. The
