Question

multiple choice question
how is chemical energy defined?
potential energy stored in the bonds of molecules
energy required for a chemical reaction to occur
energy released by the decay of atomic nuclei
kinetic energy due to the movement of molecules

Explanation:

Chemical energy is the potential energy stored in the bonds of molecules. The energy required for a chemical - reaction to occur is activation energy. Energy released by the decay of atomic nuclei is nuclear energy. Kinetic energy due to the movement of molecules is related to thermal energy.

Answer:

Potential energy stored in the bonds of molecules
