The Law of Conservation of Mass.

Work Step by Step

The Law of Conservation of Mass states that atoms are neither created nor destroyed during the course of a reaction. This means the number of each type of atom on the right side of the equation must match the number of each type of atom on the left side of the equation. This is the guiding principle for balancing chemical equations.
