The correct explanation for the change in energy during chemical reactions is:
**Energy is released by the formation of chemical bonds and energy is absorbed when the bonds are broken.**
In a chemical reaction, when reactants form products, bonds are broken in the reactants and new bonds are formed in the products. Breaking bonds requires energy, while forming bonds releases energy. If the total energy released during the formation of new bonds in the products is greater than the energy required to break the bonds in the reactants, the overall reaction is exothermic (releases energy). If more energy is required to break the bonds than is released when new bonds are formed, the reaction is endothermic (absorbs energy).
