Front

What happens to atoms during a chemical reaction?

Back

Atoms are rearranged to form new substances; they are neither created nor destroyed.

Front

What is the Law of Conservation of Mass?

Back

In a chemical reaction, the mass of the reactants equals the mass of the products.

Front

What is a Reactant?

Back
