Which one is a FALSE statement? O Balancing a chemical equation is operated on the principle of a mass balance. O If there is no coefficient or subscript, a one is implied. Coefficients are added to compounds to ensure both sides of the reaction have equal numbers of each atom. When coefficients are added, the type of compounds is changed in the chemical reaction.
