Chemical energy

If energy cannot be destroyed, what happens to the energy that is absorbed in an endothermic reaction?

The energy is stored in the chemical bonds of the products. This form of energy is called chemical energy.

In an endothermic reaction, the products have more stored chemical energy than the reactants.

So option 3 is correct.
