Answered by admin @



Answer:

Must be put in to break the bonds in the reactants and the energy that is released upon making the bonds in the products.

Explanation:

The heat energy is absorbed to break the chemical bonds, which are responsible for the attractive interactions between atoms and molecules, and which gives stability to chemical compounds. While the heat energy is released upon making the bonds in the chemical compounds.
