Chemical Reactions and Energy All chemical changes are accompanied by a change in energy Energy is either absorbed or released as the chemical change takes place. Energy is the ability to do work.
Chemical Reactions and Energy Energy is primarily released in the forms of heat and/or light Chemical reactions that release heat energy are called exothermic reactions. Chemical reactions that absorb heat energy are called endothermic reactions.
Fundamental Chemical Laws—Law of Conservation of Mass The Law of Conservation of mass says that in a chemical change, matter is neither created nor destroyed. It would be equally correct to call this the law of conservation of matter.
