Answer:
exothermic reaction: heat is released along with the formation of products in chemical reactions
eg: 1. all combustion reactions are exothermic.
2. mixing water with quick lime(CaO) to form slaked lime [Ca(OH)2]
3. respiration
(all combination reactions)
endothermic reaction: chemical reaction in which heat is absorbed
eg: 1. photosynthesis
2. manufacturing of Cement- heating calcium carbonate to form calcium oxide and carbon dioxide
(all decomposition reactions)
