transformation into one or more new substances is called a chemical reaction.<\/li>\n<li><strong>Chemical Equations\u2014<\/strong>A chemical equation is the symbolic representation of a chemical reaction using the symbols and the formulae of the substances involved in the reaction.<\/li>\n<li>The substances that react with one another are called <strong>reactants<\/strong>, and the new
