What are the new substances formed after a chemical reaction?

Explanation:
When a chemical reaction happens, atoms are rearranged to form new substances. These new substances are called products. The starting materials are the reactants. For example, hydrogen gas and oxygen gas react to form water, a substance with different properties than the original gases. Mass is conserved because all the atoms in the reactants appear in the products. Inhibitors slow down or stop reactions, and catalysts speed up reactions, but they are not the new substances produced. Reactants are simply what you start with, not what is formed.
