Acetylene gas is produced from reacting calcium carbide with what?

Explanation:
Calcium carbide reacts with water in a hydrolysis reaction to release acetylene gas and form calcium hydroxide. The balanced equation is CaC2 + 2 H2O → Ca(OH)2 + C2H2. Water provides the hydrogen needed to form the acetylene molecule, and the calcium ends up as calcium hydroxide. Oxygen, hydrogen, or nitrogen wouldn’t produce acetylene from calcium carbide in this way, so water is the reagent that generates acetylene. This is a common method for producing acetylene on demand, often used in welding and lighting.
