Introduction What is chemical change? Chemical change is the alteration of a substance into one or more different substances with different properties (also called chemical reaction). The four different types of chemial reations are synthesis‚ decomposition‚ single displacement‚ and double displacement. Synthesis is when atoms and/or molecules combine to form larger molecules. Decomposition is when a large molecules are split into elements or smaller molecules. Single Displacement has an element

industry competing against five other companies. To formulate our strategies‚ we carried out an analysis of our company’s resources using VRIO model(see appendix 1). The strategies we used were mostly emergent as we experienced some unforeseen reactions from our competitors most of the time. We engaged logical inrementalism which is “the deliberate development of strategy by experimentation and learning from partial commitment”(Johnson‚ Scholes and Whittington‚ p.408‚ 2008) in our strategy formulation

This experiment was performed to demonstrate a cycle of chemical reactions involving copper. This lab will start with copper as a reactant in the first reaction through a series of five chemical forms of aqueous phase reactions and ending to calculate the percentage of recovered solid copper as a product in the last reaction of the experiment. The experiment resulted in a percent recovery from the cycle of copper reactions of an increase to 139%. . Introduction: The purpose of this experiment is

Grignard reaction Abstract: In this laboratory‚ triphenylmethanol was synthesised from reacting benzophenone and bromobenzene using Grignard reaction. As the reaction was to set up to produce a Grignard reagent and then recrystallize it to obtain pure sample. The percentage yield obtained was 55% and its melting point was 161 co which is within the literature value 160-163 co. In addition to that the IR spectroscopy confirmed the molecule structure to be triphenylmethanol. Introduction: The Grignard

Lab #4: The Immune System Purpose: The purpose of this lab was to perform and understand the procedures of conducting an ELISA test to determine whether a particular antibody is present in a patient’s blood sample through a virtual simulation. Hypothesis: If I successfully complete this lab‚ I will then understand how to perform an ELISA test‚ the purpose an ELISA test‚ and also how to interpret the results of this test. Materials and Procedures: Materials: Howard Huges medical

Purpose: The purpose of the lab was to observe what happens when two ionic compounds are combined in a small area and to be able to record the type of precipitate that is formed. Background: An ionic compound is formed when ions “transfer‚” or lose or gain electrons. The ions in an ionic compound are held together by ionic bonds in a lattice shaped structured. They are packed tightly together to maximize the attraction between the ions. When two compounds are mixed together‚ they form a precipitate

Introduction: During this unknown lab report various test were performed to differentiate microbes from each other and to compare metabolic and biochemical process. The gram stain distinguishes between Gram positive and Gram negative bacteria based on the composition of the cell wall. The Gram stain procedure distinguishes between Gram positive and Gram negative groups by coloring these cells red or violet. Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan

DNA Extraction Lab Purpose: To compare the amount of DNA extracted from two different species‚ despite using the same method. Hypothesis: I predict that the liver will produce a higher quantity of DNA than the strawberry. This is because I believe that animals have a higher DNA yield because our structure is more complex than a plant’s structure. Materials: -Sample of Strawberries -Zip lock bag -DNA extraction buffer -Cold ethanol -Glass rod -Double ply cheese cloth -Two test tubes

what profession I would be likely to embark in. From this‚ I related closely to a forensic pathologist. This might’ve seemed abnormal at the time‚ but after I did some extended research‚ I was extremely interested. The three things that interested me about this profession were that it involves biology‚ I could help people find peace and closure‚ and I could work in a quiet environment. For the next three years‚ forensic pathology is what I planned on pursuing a career in. Once I knew what I wanted
