When Calcium ethynide is decomposed by water, the gas produced is
- CO
- H\(_2\)
-
C\(_2\)H\(_2\)
- CH\(_4\)
The correct answer is: C
Explanation
In contact with water, calcium carbide instantly decomposes hydrolytically, yielding acetylene gas and calcium hydroxide.
Calcium ethynide is also known as calcium carbide.
CaC\(_2\) + 2H\(_2\)O → Ca(OH)\(_2\) + C\(_2\)H\(_2\)
