Name: Keziah V. Cuyom Section: 9 - Malaya Topic: Types of Chemical Reaction A chemical reaction is a process that is usually characterized by a chemical change in which the starting materials (reactants) are different from the products. Chemical reactions tend to involve the motion of electrons‚ leading to the formation and breaking of chemical bonds. There are several different types of chemical reactions and more than one way of classifying them. Here are some common reaction types. However‚ if

Lab #3 Separating Metal Cations by Paper Chromatography Introduction/Purpose: In chemistry‚ it is important to effectively analyze the components in a given mixture. In order to do so‚ chemists will analyze a mixture either qualitatively or quantitatively using different methods and equipment. Qualitative analyses are subjective‚ and only gather “non-numerical” data such as the color‚ appearance‚ and smell of the components. This data

(Friday->1:35-5:35pm) | Objective: 1 mark (What is the purpose of this experiment?) In this lab‚ spectrochemical technique was used to determine qualitively the product of a reaction. The purpose was to learn what a SN1 reaction was with combining 2‚5-dimethyl-2‚5-hexanediol and HCl and to learn how to use an infrared spectrum for analyzing the reaction. The infrared spectrum determined the alcohol content present in the final product. If the IR of a molecule with an alcohol is present‚ there will
