Verified step by step guidance1
Understand that energy can exist in various forms such as electrical, kinetic, thermal, and chemical energy.
Recognize that chemical compounds store energy within the bonds between atoms; this energy is called chemical energy.
During a chemical reaction, these bonds are broken and new bonds are formed, which results in the release or absorption of energy.
Identify that the energy released during chemical reactions comes specifically from the chemical energy stored in the bonds of the compounds.
Conclude that the correct type of energy stored in chemical compounds and released during chemical reactions is chemical energy.
