What is exothermic reaction? Give example.
This reaction are release heat.Cao+H2o:Ca(OH)+2H20
The reaction in which heat is released is called exothermic reactionExothermic reaction is generally combination reactionExample:-burning of fossil fuelsCH4+O2:-CO2+H2O+HEAT
The reaction in which heat is evolved is called an exothermic reactionCaO+H2O==>Ca(OH) 2+heat

Reactions which take place with the evolution of heat ( increase of temperature ) are caled exothermic reactions. For example, burning of natural gas:- CH4(g)+2O2(g)→CO2(g)+2H2O(g)+Heat
The reaction in which heat is evolved is called exothermic reaction.
Example : C(s) + O2(g) → CO2(g) ΔH = -393.5 kJ
