Tyler White CHEM151LL 32658 04/01/2018 Different Types Chemical Reaction Types and Equations Purpose: The purpose of this lab experiment is to examine different types of chemical reactions such as Decomposition reaction, Synthesis reactions, Combustion reactions, and different Chemical equations. The experiments were conducted online using Late Nite Labs. Materials: Because the experiments were conducted online there wasn’t any physical use of materials, only digital ones, for these labs to be performed. Only the registration for the website was needed to perform these online labs, as well as a desktop computer.

In this experiment, a balanced chemical equation will be provided for decomposition reactions. A redox reaction is a reaction where one reactant is reduced due to a gain of electrons, and the other is oxidized due to a loss of electrons. The reactant that loses an electron is called the reducing agent, whereas the reactant that gains an electron is called the oxidizing agent. In this experiment, the balanced chemical equation, and the two half equations for the redox reactions will be provided, and the oxidizing and reducing agents will be
3.1 Project Methodology In order to make sure that this project is on track, proper planning and scheduling is crucial. It is necessary to identify the significant key points which are photocatalytic activity of SWCNTs, properties of carbon nanotubes and titanium oxide, available testing procedures using scanning electron microscopy (SEM) and other spectroscopic methods. In this section, a brief detail provided regarding the methods used, sol-gel, hydrothermal and electrospinning. Also, the available tests that will be used are explained.
Abstract In this laboratory, methanol is reacted with a tertiary alkyl chloride to make ether. The triphenylmethyl is isolated from the triphenylmethyl chloride. Methanol is then added and the class does the recrystallization . The methanol acts as a solvent for the reaction as a nucleophile.
With many factors affecting chemical reactions, there is a significant relationship between these factors and the rate that they occur. As seen through many studies and experiments, surface area of solid reactants has a great impact on this rate of reaction. In conclusion, the scientist has learned important relationships and factors involved in the rate of which chemical reactions
The purpose of this experiment was to learn about metal hydride reduction reactions. Therefore, the sodium borohydride reduction of the ketone, 9-fluorenone was performed to yield the secondary alcohol, 9-fluorenol. Reduction of an organic molecule usually corresponds to decreasing its oxygen content or increasing its hydrogen content. In order to achieve such a chemical change, sodium borohydride (NaBH4) is used as a reducing agent. There are other metal hydrides used in the reduction of carbonyl groups such as lithium aluminum hydride (LiAlH4).
In this lab, the oxidation of a secondary alcohol was performed and analyzed. An environmentally friendly reagent, sodium hypochlorite, was used to oxidize the alcohol, and an IR spectrum was obtained in order to identify the starting compound and final product. The starting compound could have been one of four alcohols, cyclopentanol, cyclohexanol, 3-heptanol, or 2-heptanol. Since these were the only four initial compounds, the ketone obtained at the end of the experiment could only be one of four products, cyclopentanone, cyclohexanone, 3-heptanone, or 2-heptanone. In order to retrieve one of these ketones, first 1.75g of unknown D was obtained.
While the absolute value of slope of the graph for the solution containing only 0.5 mL mitochondrial suspension was 4 x 10-4, the slope of the graph for the solution containing 0.5 mL of mitochondrial suspension, 0.5 mL of 100 mM succinate, and 0.5 mL of 100 mM malonate was 7 x 10-4. Although this change is not large, it does demonstrate that the addition of TCA cycle intermediates has an impact on reaction rate. The decrease in the rate of reaction of the sample containing 0.5 mL of mitochondrial suspension, 0.5 mL of 100 mM succinate, and 0.5 mL of 100 mM malonate as compared to the sample with only 0.5 mL of mitochondrial suspension and 0.5 mL of 100 mM succinate shows that the addition of malonate inhibits the reduction of
Exergonic Reaction with Catalyst First, pour about 15 ml of substrate solution into a 25 ml beaker. Then, put the substance in an hot water bath and set it to 30â€¹C. Next, add a filter paper disk soaked in yeast solution and record the time it takes for the disk to rise to the top of the solution. Repeat steps 2 and 3 2 more times for 30 â€¹C and 3 times for 40â€¹C. Finally place the solution in a ice bath for 20â€¹C and repeat steps 2 and 3 3 more times. First, pour about 15 ml of yeast solution into a 25 ml beaker. Then, add a filter paper disk soaked only in water in the substrate solution and wait until it sinks to the bottom.
The acid-catalysed dehydration of a secondary and primary alcohol revealed that the E1 mechanism undergoes and favors rearrangement for a more stable carbocation; this reaction favors a Zaitsev product, which attacks the most substituted beta hydrogen. The base-induced dehydration of a secondary and primary bromide undergoes an E2 mechanism and favors a Hoffman product because of the presence of a sterically bulky base, which attacks the least substituted beta hydrogen. The percent compositions obtained through Gas Chromatography revealed that these favored types of products were present in the highest
*The order Chelonia includes tortoises, terrapins and turtles. *They are described as ‘reptiles in boxes’ as their body is enclosed in box like dorsal carapace and ventral plastron. *Chelonians are believed to be the direct descendants of primitive cotylosaurs. *They are ectothermic, which implies that their body temperature remains close to the temperature of their environment, and they are rely completely on external sources of heat.
Because the heating block readily increased in temperature, the temperature had to be adjusted accordingly to prevent the overheating the reaction. Initially, the color of the reaction turned into a dark green color and over time became a lighter shade with a minimal solid left. The reaction process lasted for 2 hours. As the reaction heated for 2 hours, a 50 mL beaker was weighed, approximately 12 mL of 20% ethyl acetate in hexane solution was added to a 25 mL Erlenmeyer flask, and 2.0 mL of saturated NaCl solution was added to a labeled test
