Our mission is to provide a free, world-class education to anyone, anywhere. A chemical equation describes what happens in a chemical reaction.The equation identifies the reactants (starting materials) and products (resulting substances), the formulas of the participants, the phases of the participants (solid, liquid, gas), the direction of the chemical reaction, and the amount of each substance. In writing chemical equations, the number in front of the molecule's symbol (called a coefficient) indicates the number of molecules participating in the reaction.If no coefficient appears in front of a molecule, we interpret this as meaning one.
