Chemical equations are illustrations of the reactants and products in a chemical reaction. Chemical equations are expressed as A + B - C, where A and B are the reactants, and C is the product. More »

The chemical equation for the combustion of hydrogen is 2H2 + O2 → 2H2O. During hydrogen combustion, the heat from burning makes hydrogen chemically react with oxygen gas, O2, in the air to form water. More »

Chemical equations are balanced to satisfy the law of the conservation of mass. Since the law states that matter cannot be created or destroyed, a balanced equation is necessary to ensure the same amount of matter in bot... More »

A chemical reaction occurs when the reactants break into constituent ions and recombine to form different products. In this case, lead nitrate and potassium chromate recombine to form lead chromate and potassium nitrate.... More »

Skeleton equations are created by placing the reactants, separated by plus signs, on the left-hand side, and the products on the right-hand side. These skeleton equations are generally unbalanced because they imply that ... More »

Stoichiometry is a branch of chemistry that deals with the relationship between reactants and products involved in a chemical reaction. In other words, it deals with calculations of masses or volumes of relative quantiti... More »
