Question

An endothermic reaction is one that uses which form of energy? nuclear fusion sound energy chemical energy electrical energy

Answer 1

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.

Answer 2

An endothermic reaction is the one that use : Chemical energy

Chemical energy refer to the energy that is stored within the bound of the compound (endothermic reaction absorb heat to produce energy)

hope this helps
