Answer 2

Answer:

Exothermic reactions convert chemical energy (enthalpy) inside chemical substances into heat energy. The chemical energy decreases, and the heat energy increases (total energy is conserved). ... BOND MAKING RELEASES ENERGY, RATHER THAN NEEDING IT TO BE SUPPLIED, so as a result of the bond making, heat energy is released.
