Calcium carbide reacts with water to give ethyne or acetylene gas and calcium hydroxide. Write the balanced chemical equation for this reaction.

Text Solution

Verified by Experts

The skeleton equation is
`CaC_(2) (s) + H_(2) O (l) rarr HC -= CH (g) + Ca (OH)_(2) (s)`
a. Order of selection of atoms for balancing is `O, H`,and `C`.
The number of `O` atoms on `RHS` is 2, and one `O` atom on `LHS`. So multiply `H_(2) O` with 2.
`CaC_(2) (s) +2 H_(2) O (l) 0gt HC -= CH (g) + Ca (OH)_(2) (s)`
It is a balanced chemical or atomic equation.
