Answer 2

Hello Dost ☺

Answer : oxidation may be exothermic n endothermic.. defend on what reaction going on.. heat is produced or heat absorb.

more info :

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
