Explain the difference between the reactants and products of a chemical reaction.
Reactants are the starting substances and products are the ending substances in a chemical reaction. The atoms in reactants are arranged one way and are rearranged in a different way to form the products (in other words, reactants are chemically different from products). The properties of reactants differ from the properties of products.
