An exothermic reaction is a chemical reaction in which the heat energy of the surroundings increases, due to the release of energy from chemical bonds. The opposite of an exothermic reaction is an endothermic reaction in which the heat energy is taken in as opposed to given out. An exothermic reaction can be called a 'heat giving' reaction. Exothermic reactions are associated with the making of stronger chemical bonds.
Examples of Exothermic Reactions:Combustion reactions of fuels or a substance
Neutralization
Deposition of dry ice (carbon dioxide) from the gaseous state
Adding water to anhydrous copper(II) sulfate
The thermite reaction
Reactions taking place in a self-heating can based on lime aluminium
Many corrosion reactions such as oxidation of metals
Decomposition of vegetable matter into compost
Solution of sulfuric acid into water
Dehydration of sugars upon contact with sulfuric acid
Detonation of nitroglycerin
Nuclear fission of uranium-235
