When an equation of a chemical reaction is written, it is “balanced” to show this. A balanced chemical equation shows that no atoms are destroyed and no new atoms are created in the chemical reaction.

Chemical equations must be balanced so that the quantities of reactants and products match. For an equation to be balanced there must be an equal numbers of atoms on each side.
