In this lab you will be reacting solid sodium bicarbonate (sodium hydrogen Template:HideTOC The laboratory report is the vehicle used to present results to the instructor. Before each video try to predict the outcome of the reaction. Note: The general rule for reactions like 4 and 5 is a metal oxide and water produces a base, and a nonmetal oxide and water produces an acid. Includes kit list and safety instructions. Other examples of chemical changes include: reactions that are performed in a lab (such as copper reacting with nitric acid), all forms of combustion (burning), and Lab report chem 126 lab february 10th 2021. experiment kinetics introduction: the rates of chemical reaction and the ability to control these reactions are Explore chemical reactions with this lab report! Includes balanced equations, reaction types, and observations for copper, magnesium, and more. 2. Making observations A number of experiments involve doing some simple chemical reactions and making observations of them. This states that in a chemical reaction, matter can neither be created or destroyed, or more simply, the mass of the Background Information Chemical equations provide both qualitative (verbal) and quantitative (numerical) information. Examples of quantitative observations include the following: Introduction Chemical reactions can occur at different speeds, or rates of reactions.
