Chemical Reactions That Release Energy?

Answer

Chemical reactions that release energy are called exothermic reactions because they release energy in the form of heat. An exothermic reaction can be chemical or physical. Some examples of exothermic reactions are combustion reactions of fuel, adding concentrated acid to water, burning of a substance, burning of natural gas, respiration, and decomposition of vegetable matter into compost. If you wish to measure the the heat production you would need to use a reaction calorimeter, this will monitor the heat flow.
