Question

what happens to energy during a chemical change

Answer 1

Energy is used to break bonds in reactants, and energy is released when new bonds form in products. Endothermic reactionsabsorb energy, and exothermicreactions release energy. ... Whether a chemical reactionabsorbs or releases energy, there is no overall change in the amount of energy during thereaction.

Answer 2

As the law of conservation of energy states Energy can neither be created nor be destroyed. So during a chemical reaction the energy gets converted to heat and light energy.
