Chemical reaction

optimal for enzyme functionality and how they affect enzyme functionality. Enzymes help speed up chemical reactions in the body and lower the activation energy to do so. Enzymes can also aid with metabolism and digestion. They can break down larger molecules to smaller molecules that are more easily absorbed by the body. A substrate is the reactant that is acted upon by an enzyme in a chemical reaction. The substrate attaches itself to the active site, the place where the enzyme catalyzes. The…

yield to the theoretical yield. The actual yield is the amount or mass of product actually collected during an experiment or industrial process, while the theoretical yield is the amount or mass of product predicted based on the stoichiometry of the chemical equation. In order to calculate the theoretical yield, the number of moles (the amount of substance containing 6.02x1023 entities) of each compound should be calculated according to the formula: n = m/M Where n is the number of moles, m is…

of plants and animals. There are called catalysts, which are substances that control how quickly chemical reactions occur without interfering at the reaction products (Daja and Treska 2015). Structure of both the enzyme and substrate, the substance on which an enzyme acts; provides clues as to how an anticipated reaction can be favored by the alignment of catalytic residues (Johnson 2008). The reaction of an enzyme is represented as: In this equation, when there is enough substrate (S) to…

carbon dioxide escaping from the solution. White foam overflowed over the rim of the container. I felt the cup dropping temperature slightly as the reaction took place. The temperature dropped about 6 degrees Celsius. The remaining solution was a filmy and diluted. The result was sodium acetate dissolved in water. This reaction was a double displacement reaction. The sodium bicarbonate reacted with the acetic acid vinegar and produced sodium acetate, water, and carbon dioxide. The carbon dioxide…

equilibrium. A molecular explanation for the results in figure 1 is that polyphenol oxidase is a catalyst that lowers the activation energy, which speeds up chemical reaction, to reach a transitional state leading to the formation of pink/gold melanin (Brooker (2014). If the activation energy is not lowered it will act as a barrier that will slow the reaction of products, which in this case is pink/gold melanin. By polyphenol oxidase lowering the activation energy, the…

the Industrial Revolution, hydrochloric acid is used in the chemical industry as a chemical reagent in the large-scale production of PVC plastic, and MDI/TDI for polyurethane. It has numerous smaller-scale applications, including household cleaning, production of gelatine and other food additives, descaling, and leather processing. About 20 million tonnes of hydrochloric acid are produced worldwide annually. Chemical properties and reactions: Hydrogen chloride (HCl) is a monoprotic acid, which…

the empirical formula of a compound when the amount of it is known. By dehydrating the copper chloride hydrate sample and using it for an elemental copper-producing chemical reaction, one can isolate the masses of the water, copper, and chloride and determine their mole ratios. Since the Law of Definite Proportions states that a chemical compound always contains fixed proportions of its constituent elements by mass, the mole ratios can be used to find the empirical formula of the copper chloride…

Chemistry and the Diels-Alder Reaction Purpose The purpose of this reaction is to bring about the movement of green chemistry which is a safer, more sustainable chemistry to all levels of chemistry. The use of 12 principles can make in principle a reaction greener with the use of modifications. In this lab, the Diels-Alder reaction will be performed by reacting (E,E)-2,4-hexadien-1-ol with maleic anhydride without the use of a solvent to make the reaction more greener. The reaction will be…

Combustion is a chemical reaction between substances, according to www.scienceterms.com, "[Combustions processes] usually including oxygen and usually accompanied by the generation of heat and light in the form of flame. The rate or speed at which the reactants combine is high, in part because of the nature of the chemical reaction itself and in part because more energy is generated than can escape into the surrounding medium, with the result that the temperature of the reactants is raised to…

Frame: The purpose of this lab is to determine if the iron given in the experiment is Fe (II) or Fe (III). Knowing what chemicals are present in a reaction and what chemicals are produced is significant information that can be applied to real world situations. An example of this is rust. Rust usually occurs when iron reacts with water. By being aware of this, substances can be made to remove unwanted rust. The mass of the collected samples will decrease as it is dried due to evaporation. Excess…
