Chemical energy is defined as:

Explanation:
Chemical energy is energy stored in chemical bonds that can be released during reactions. This energy sits in the way atoms are arranged and bonded, so when bonds are broken and new bonds form, energy can be released as heat, light, or used to do work in the cell or environment. For example, burning fuel breaks chemical bonds and forms new, more stable bonds in the exhaust, releasing energy that heats or powers engines. In your body, food is broken down to release stored chemical energy that your cells use to make ATP and drive cellular processes, and plants capture energy from sunlight to store it in glucose through photosynthesis. The other ideas describe different kinds of energy. The rate at which electric charges move describes electrical current, not chemical energy. The energy due to an object's position in a field describes potential energy from gravity or electric fields, not chemical bonds. The energy stored in a magnetic field is magnetic energy, another separate form.
