Answer 2

Answer:

Exothermic Reaction :- Reaction in which heat is released out.

Example :-

Combustion of fossil fuel

CH4 + O2 -> CO2 + H2O + Heat

Thermite Reaction

Al + Fe2SO4 -> Fe + Al2O3 + Heat

Endothermic Reaction :- Reaction in which energy is absorbed.

Example:-

CaCO3 + CaO + CO2

Photosynthesis process :-

CO2 + H2O -> C6H12O6 + O2
