Wittig reaction

to test the rate of reaction in cold temperatures, the next sample was heated to 30° to resemble human body temperature which is 37° (HealthLinkBC, 2016), the third and fourth samples were set to 50° and 70°, respectively, to measure the effects heat on the enzymes, the last sample was left at room temperature, 24°, and used as a control. According to enzyme theory, as the temperature of a reaction increases, the amount of energy within a system increases, allowing reactions to occur more readily

decomposition produces NO, O2, Cl2, and H2O. At this point, these products result in the formation of the Monopropellant Flame as they react. Reaction kinetics in the Monopropellant Flame is also captured in a simple Arrhenius expression (Equation 3.4) to determine mass flux. m_AP= A_AP exp(-E_AP/RT_AP ) (3.4) In the Monopropellant Flame the reaction rates are fast and are not impeded by diffusion since the gaseous AP decomposition products are reactive components that are already

Purpose: The purpose of this experiment is to form Copper (II) phosphate trihydrate and determine its actual yield by identifying the limiting reactant in the reaction. It also includes calculating the percent yield by finding the theoretical and experimental yield of the precipitate. The limiting and the excess reagents will be figured out using the mole ratios in the chemical formula. Procedure: For the first part of the experiment, 15 ml of copper (II) chloride solution and sodium phosphate solution

with the two solutions, hydrochloric acid and copper chloride. The nonmetals, sulfur and carbon, did not undergo a chemical reaction with either solution. Both metalloids, silicon and unknown 2, also did not undergo a chemical reaction, possessing the traits of a nonmetal. Zinc, tin, lead, magnesium, and unknown 1 all

In this laboratory the objectives were to understand the effects that temperature has on a reaction, be able to calculate the reaction’s rate constant, and to calculate the activations energy from the recorded rate constant. Activation energy is the minimal amount of energy that is necessary to result in a chemical reaction. With an insufficient amount of energy, a reaction won’t occur, too much and it will react just fine. A great example of this can be lighting a match. The friction created when

considered catalysts that speed up chemical reactions without being used in the process. Enzymes react with substrates to form a temporary intermediary complex from which the new product gets released. The enzyme that is unchanged and released at the end of the reaction will be able to again combine with more substrate until all of the substrate is utilized. The enzymes in living cells immensely accelerate chemical reactions and by governing relative reaction rates, regulate the directions of metabolic

that reactions occurred in all four test tubes. This means that all four test tubes turned out to be positive reactions. The data collected regarding the reactions did not meet the expectation. The expectation was that two out of the four tubes would yield a reaction. To be specific, the expectation was that only one of the first two tubes would have a reaction, and only one of the second two tubes (tubes 3&4) would have a reaction. This was the expectation because the goal of the reactions was to

double displacement reaction is defined as a component from each chemical forming together and swapping to form a completely new chemical. The cations and anions switch places to form two different components. For example AB + CD → AC + BD. This basically explains that chemicals swap different components with each other to produce completely new components. For this practical report the chemicals used were Sodium Carbonate and Hydrochloric Acid, Potassium iodide and Silver nitrate and Barium Chloride

synthesize 2-methyl-1-butene and 2-methyl-2-butene. We later confirmed the alkenes in each product with Baeyer and Bromine test. Through Gas liquid chromatography we could calculate the yield percentage. E1 and E2 are similar yet, different reactions. In the E1 reaction, the rate determining step is the loss of the leaving group when the mixed with a solvent and an energy source is provided, in this case it was heat. This step produces a carbocation. A tertiary carbocation is preferred because it is more

enzyme is a catalyzes chemical reactions with in a cell. Enzyme are specific on a certain kind of substrate this is based on the structure of the active site if the enzyme, the site where the substrate reaction occurs, and the structure of the substrate. The active site binds with the substrate and creates an environment that is optimal for the substrate chemical reaction to occur. The enzyme does this by lowering the activation energy required for the chemical reaction. This allows the cell to increase
