Question

write differences between exothermic and endothermic reactions

Answer 1

The difference between endothermic and exothermic reactions lies in the words themselves. "Thermic" refers to heat, just as in the word "thermometer." "Exo" means "outside" and "endo" means "inside." Thus, an endothermic reaction pulls heat into an object or area, while an exothermic reaction expels heat. From this basic definition of the terms, you can understand a variety of other facts about these two types of chemical reaction.

Answer 2

exothermic reaction- reaction which produce heat
endothermic reaction - reaction which recieve heat
