Answer 1

hola mate

here is ur answer

hope this helps

❤❤❤

Endothermic reaction is such which occurs only on absorption of heat energy .

Exothermic reaction is such which liberates heat energy.

An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.”

mixing water with calcium chloride is exothermic

evaporation of water is endothermic

Answer 2

Hello Dost ☺

Answer :

Exothermic reaction and endothermic reaction:

On the basis of energy changes during chemical reaction, they can be classified as

i) Exothermic reaction: A chemical reaction in which heat energy is produced.

Eg : C + O2 → CO2 (g) + heat

ii) Endothermic reaction: A chemical reaction in which heat energy is absorbed.

Eg : CaCO3 + Heat → CaO + CO2
