How does a balanced chemical equation demonstrate the Law of Conservation of Mass?

Question

A. it shows that only physical changes follow the Law of Conservation of Mass
B. it shows that the properties of the elements stay the same after the reaction
C. it shows that no atoms have been gained or lost during a reaction
D. it shows that all compounds remain bounded after the reaction

Answer 1

C. it shows that no atoms have been gained or lost during a reaction

A balanced chemical equation demonstrates the Law of Conservation of Mass by showing that the number of atoms of each element is the same on both the reactant and product sides of the equation. This indicates that no atoms are created or destroyed in a chemical reaction, thereby illustrating that mass is conserved.
