Detailed explanation-1: -Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.

Detailed explanation-2: -According to the modern view of chemical reactions, bonds between atoms in the reactants must be broken, and the atoms or pieces of molecules are reassembled into products by forming new bonds. Energy is absorbed to break bonds, and energy is evolved as bonds are made.

Detailed explanation-3: -For a reaction to take place, bonds in the reactants have to be first broken. The atoms then rearrange, and bonds form to make a new product. The amount of energy change in a reaction depends on the amount of bonds broken and formed.

Detailed explanation-4: -Breaking Bonds: All chemical reactions that produce products different than the reactants requires the breaking of chemical bonds inthe reactants in order to make new chemical bonds in the products.
