Question

Please give differences and similarities between endothermic and exothermic 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.

Answer 2

exothermic- release heat,generally combination reactions
endothermic- absorb heat, generally decomposition reactions

similarities

both are chemical reactions
chemical change take place
involves energy
can't be reversed
