The product obtained a result of a reaction of nitrogen with `CaC_(2)` is

Options

A. `Ca_(2)CN`
B. `CaCN_(2)`
C. `CaCN`
D. `CaCN_(3)`

Answer

2

Explanation

Calcium cyananmide `[Ca^(2+)N^(-)=C=N^(-)]` is formed :
`CaC_(2)+N_(2) overset(1273K)rarrCaCN_(2)+C`
since calcium cyanamide reacts with water to yield ammonia it is used as a fertilizer under the name nitrolim `(CaCN_(2)+C)`
