Multiple Choice

All chemical reactions, absorb or release __________.

Explanation:
Chemical reactions involve changes in energy. When bonds are broken, energy must be put in; when new bonds form, energy is released. This means reactions can either absorb energy from the surroundings (endothermic) or release energy to the surroundings (exothermic). Because every chemical reaction involves some change in energy, energy is what gets absorbed or released. Light or sound emission can happen in some reactions, but they are not universal outcomes, and matter is rearranged rather than simply absorbed or released.
