Question

What happens when heavy water is added to calcium carbide?

Answer 1

This reaction was the basis of the industrial manufacture of acetylene, and is the major industrial use of calcium carbide. At high temperatures, CaC2 reacts with water vapor to give calcium carbonate, carbon dioxide and hydrogen.
CaC2(s) + 2H2O(l) = C2H2 (acetylene gas) + Ca(OH)2(s)

Answer 2

Answer;c2d2 is formed

Explanation:
