CaC(2) + N(2) to...

`CaC_(2) + N_(2) to`

A

`CaCN_(2)`

B

`CaCN_(2)` and C

C

`CaCN_(2)+N_(2)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
When calcium carbide reacts with nitrogen at `1000^(@)C`, calcium cyanide and carbon is formed.
`CaC_(2) +N_(2) overset(1000^(@)C)to underset("Calcium cyanide")(CaCN_(2)+C)`
