Matter cannot be created or destroyed by a chemical change. During a chemical change (reaction), the atoms of one or more substances (reactants) simply undergo some "rearrangements". The result of these rearrangements is the formation of new, different substances (products). All of the original atoms are still present. The total mass of the reactants before a chemical reaction will equal the total mass of the products after the chemical reaction.
