Answer 1

an exothermic reaction are chemical reaction that release heat energy to the surrounding

an endothermic reaction are chemical reaction that absorbs heat energy from the surrounding

Answer 2

Answer:

endothermic reaction:- reaction in which energy is absorbed

eg:-

$caco _{3} \: + \: heat \: = \: cao \: + \: co_{2}$

exothermic reaction :- reaction in which heat is released along with the formation of products.

eg:-

$cao \: + \: h_{2}o \: = \: ca(oh) {2} \: + \: heat$

Trick:

endo means (in) "absorbing " energy

exo means (exit) "releasing " energy
