Question

Why reaction of calcium carbide with water is exothermic?

Answer 1

hey ❕ here's your answer

CaC2 reacts exothermically with waterforming calcium hydroxide and acetylene, an extremely flammable gas.hope this is the which which u wnt
hope it helps you

Answer 2

CaC2 reacts exothermically with waterforming calcium hydroxide and acetylene, an extremely flammable gas. The heat of the reaction can be sufficient to raise the temperature above the ignition point for acetylene (305 °C) whereupon the mixture of acetylene with air is likely to explode.

hope it clarifies ur doubt dear friend ...
