6. Key terms chemical equation A symbolic representation of a chemical reaction; reactants are represented on the left and products on the right. coefficient A constant by which an algebraic term is multiplied. law of conservation of mass Matter cannot be created or destroyed. Therefore, in a closed system, the mass of the reactants must equal the mass of the products. product The compounds produced by a chemical reaction. reactant The starting materials in a chemical reaction.
