The Law of Conservation of Mass – during a chemical reaction, the mass before the reaction must equal the mass after the reaction. We show this by writing and balancing a chemical equation. When we write a chemical equation, we use the chemical symbols for the elements and subscripts to indicate how many atoms of each element are present in the reaction.
