Question

Give an example of endothermic and exothermic with chemical equation

Answer 1

Exothermic reaction = reaction of quick  lime  with water to form slaked lime

Cao + H2o → Ca(OH)2

Endothermic reaction = Ferrous sulfate crystals heated to get ferrous and water

FeSo4.7H2o on heating → FeSo4 +7H2O

Answer 2

Exothermic reaction-

C + O2 ----> CO2 + heat

CH4 + 2O2---> CO2 + H2O + heat

Endothermic reaction-

N2 + O2 ----> 2NO (on heating)

CaCO3 ----> CaO + CO2  (on heating)
