Explain endothermic and exothermic reaction |
|
Answer» The reaction in which energy is released in the form of heat, light and electricity is called exothermic reaction. The reaction in which energy is absorbed in the form of heat, light and electricity is called endothermic reaction. The chemical reaction in which heat is given out is known as exothermic reaction.Ex:-magnesium oxide + water = magnesium hydroxide. In this reaction a lot of heat is produced ,enough to give boles on hand.This reaction in simple language is the reaction between choona and water. The reaction in which the product formed has low temperature than the reactactants is called endothermic reaction.Eg sodium chloride + water = sodium hydroxide + hydrochloric acid. In dimple language the reaction between salt and water is an endothermic reaction. If you try then dont touch the product in exothermic but you can touch the product in endothermic.Thank you. Those reaction in which heat is evolved is called exothermic reaction and those reaction in which heat is absorbed is called endothermic reaction |
