factors of a chemical reaction affect the rate of reaction. This experiment focused on how temperature affects the rate of reaction for the reaction of alka-seltzer and water. The rate of a reaction is a value calculated to figure out how fast a chemical reaction occurs. There are three factors that can be changed that will affect the rate of a chemical reaction: surface area‚ concentration‚ and temperature. Temperature specifically affects the rate of a chemical reaction‚ because when the temperature

Aim It is to tell how the reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid. Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. The balanced formula for this is: Mg(s) + 2HCL(aq) MgCl2(aq) + H2(g) Magnesium + hydrochloric acid Magnesium Chloride + Hydrogen Magnesium will react with hydrochloric acid‚ because it is higher in the reactivity series than hydrogen

Chemical Reactions The idea of chemical reactions was investigated about two hundred and fifty years ago‚ when a man named Antoine Laurent Lavoisier wanted to know about the importance of chemical changes. Also‚ in the 19th century‚ John Dalton made the atomic theory. Dalton said that bonding atoms together makes new substances‚ which is a chemical reaction (History of chemical reactions). The definition of chemical reaction is‚ “the processes in which substances undergo chemical changes‚ which

This experiment involved a substitution reaction to perform synthesis of 2-phenylethanol to get (2-bromoethyl)benzene. Using NaBr in an acidic solvent of H2SO4 with H2O present‚ this synthesis was possible. Subsequent evaluations using TLC and then analyzed samples by Gas Chromatography were done to evaluate the results. Using SN2 reactions‚ primary alcohol is going to be converted to alkyl halide. Since the reaction can be reversed‚ the strong sulfuric acid was to make sure the product would indeed
