This document contains notes from chemistry lessons on 23/09/15 covering reactions of metals, metal compounds, carbonates, and oxides with acids. It includes example reactions and spaces for students to write out additional reactions, such as calcium + hydrochloric acid yields calcium chloride + hydrogen. The document also covers testing for hydrogen gas and carbon dioxide gas, as well as neutralization reactions between acids and bases.
