The statement that is true about what happens during a chemical reaction is "bonds of the reactants are broken, and bonds of the products are formed."
Chemical reactions are common under the conditions of planet Earth. When two or more molecules interact and change, that is when a chemical reaction is produced. Atoms bonds are broken and create new molecules. In chemical reactions, a large series of reactions are the product of single reactions. For instance, rust is the by-product of the combination of oxygen and iron.
