In order for a chemical reaction to occur, mass needs to be conserved as reactants are transformed into products. This means the atoms that start a reaction must end the reaction. The mass of these atoms is the same on both sides of the equation because the amount of atoms on both sides of the reaction is equal. This is shown in a chemical equation. A balanced chemical equation represents the substances involved in the reaction. The amounts are balanced with the use of coefficients. Balancing the equation ensures that the law of conservation of mass is upheld.
