Such reactions are called Exothermic reactions.
Exothermic reactions produce heat. Endothermic reactions take in heat from the surrounding area and get cold.
Energy is given off during exothermic reactions, where the system releases heat to the surroundings. Examples include combustion reactions, neutralization reactions, and some types of nuclear reactions.
Combustion reactions are exothermic.
exothermic reactions are the reactions which give out heat and endothermic reactions are the reaction which absorb heat.so combustion is an exothermic reaction.
Endothermic and exothermic reactions are similar in that both have reactants and products. They are different in that exothermic reactions release energy through reacting and endothermic reactions absorb it.
In general, exothermic reactions are faster than endothermic reactions. This is because exothermic reactions release energy, which can help drive the reaction forward more quickly.

An exothermic reaction releases heat
A reaction that gives off energy is an exothermic reaction. The reaction will give off energy in the form of either heat or light An example of an exothermic reaction would be the curing of concrete. One chemical reaction that will give off heat is the mixture of Caustic Soda and water. The water dissolves the Caustic Soda which in turn generates heat. There are two types of reactions. Exothermic reactions give off heat, and endothermic reactions require that heat be added to make them work. Be careful with exothermic reactions. A rapid, energetic exothermic reaction is called an "explosion".
Exothermic reactions can be both decomposition reactions (breaking down a compound into simpler substances) and synthesis reactions (forming a compound from simpler substances). The key factor that determines whether a reaction is exothermic is whether it releases heat to its surroundings.
The term "exothermic change" typically refers to a chemical reaction that releases energy in the form of heat. This makes me think of reactions where heat is given off to the surroundings, signifying that the reaction is exothermic.
