D.? my notes say
When you mix certain substances, a reaction can occur and form new substances. Reactants are the substances that are mixed to react with each other. Products are the substances produced by the chemical reaction. Energy is always involved in chemical reactions. An exothermic is the name for a chemical reaction that releases energy. An endothermic is the name for a chemical reaction that absorbs energy. There are many different types of chemical reactions. Decomposition is t breaks down into different products. Precipitation is the name for the process in which a solid product forms during a reaction involving a liquid reactant.
