Kinetic investigation and the Arrhenius plot The degradation of SAC in acidic, basic and oxidative mediums at different HCl (0.01, 0.05 and 0.1 M, keeping temperature 90 ºC), NaOH (0.005, 0.01 and 0.05 M, keeping temperature 40 ºC) and H2O2 (5%, 10% and 15%, keeping temperature 90 ºC) strengths was studied. Also SAC degradation was studied as a function of temperature in acidic (30, 60, 70, 90ºC and room temperature, keeping HCl strength 0.1M), basic (40, 65, 90ºC and room temperature, keeping…

of an invaluable chemical reaction (The Nobel Prize in Chemistry 1950). The reaction they described was for the formation of carbon-carbon bonds in a six membered ring with exceptional control of its stereochemistry in one step (Diels-Alder Reaction Gains Nobel Prize). This was an important discovery due to the fact that six membered rings are abundant natural products and man-made products. Several new compounds were synthesized as a result of the Diels-Alder reaction including: Reserpine,…

Concentration on Catalase Reactions Blake Devivo Biol 101 Lab February 10, 2016 Abstract The human body contains thousands of tiny structures called enzymes that perform specific functions. One enzyme called “Catalase” is often used to regulate the amount of a toxic compound, hydrogen peroxide, in the body. The purpose of this experiment was find the different factors that can affect Catalase-Peroxide reactions. The first part of this experiment demonstrated that catalase reactions with…

chemical reactions such as combustion and displacement, how to write word equations about chemical reactions and the difference between exothermic reactions and endothermic reactions. To write combustion as a word equation you would write ‘___ -> Oxygen = ___ Oxide’ so if the element you were burning was Iron, the product would be Iron Oxide. In a chemical reaction, the surroundings may increase or decrease in temperature due to exothermic and endothermic reactions. An exothermic reaction is…

Based on the results of the control experiments, the interaction between the Calcium Chloride and phenol red are responsible for the high temperature change in the overall reaction. After doing a control experiment with Sodium Bicarbonate and phenol red and noticing that the temperature got colder, only one other chemical mixed with phenol red could be responsible for the warm temperature change that chemical being Calcium Chloride. There was a temperature change that was observed during the…

The substances found on the victims of the crash can be easily identified through simple math. You start by taking the percent values of each element found in the substance and changing it to grams, where one percent equals one gram, so that each element is out of one hundred grams. After finding the grams, you find out the moles of each element by multiplying the gram amounts by the conversion factor, which is 1 mol over the molar mass of the element you are dealing with, 12.01 grams for carbon…

Maci Mullins CHEM2130-001 12/8/2017 A Wittig Reaction of trans-Cinnamaldehyde Statement of Question: What is the stereochemistry in the Wittig product, and why is it formed? Hypothesis: There were two possible stereochemical outcomes for this experiment, either cis, (E,Z), or trans, (E,E). The cis product, (E,Z), would form if the double bond and phenyl group added to the same side. The trans product, E,E), would form if the double bond and phenyl group were to add to the opposite sides.…

selective oxidizing agent. This reaction is an oxidation reaction. The reaction involves the removal hydrogens and sometimes the addition of oxygen. 2-ethyl-1,3-hexanediol will undergo an oxidation reaction to produce an unknown product (Scheme 1). (1) Scheme 1. 2-ethyl-1,3-hexanediol undergoes a reaction with sodium hypochlorite and glacial acetic acid to produce an unknown product. There are three possible outcomes when 2-ethyl-1,3-hexanediol undergoes the oxidation reaction (Scheme 2,…

adverse reactions? When you start a new medication or therapy, you should watch for serious side effects, called adverse reactions. They occur when a patient experiences undesirable and unexpected effects to a health product. Under Health Canada guidelines, “health products” include drugs (prescription and over-the-counter), medical devices, and natural health products, such as herbal supplements or vitamins. Not all reactions to health products are considered adverse reactions. Some…

PCR (Polymerase chain reaction) Polymerase chain reaction (PCR) is a laboratory method that is used to form number of copies of a specific region of DNA interested in. The principle of the polymerase chain reaction is based on the natural replication process of DNA and complementary nucleic acid hybridization. The goal of the PCR is to produce required amount of the target DNA region that is be analyzed. PCR amplified DNA is sent for sequencing and visualized by gel electrophoresis. It also can…
