Nitrolim is a mixtrue of

A

`CaCN_(2)+N_(2)`

B

`CaCN_(2)+` graphite

C

`CaCN_(2)+` diamond

D

`CaC_(2)+` graphite

Text Solution

Verified by Experts

The correct Answer is:
2
The mixture of calcium cyanamide,`CaCN_(2)` and graphite ,`C`, is technically known as nitrolim.
Calcium cyanamide a black crystalline power made by heating calcium dicarbide `CaC_(2)` in nitrogen at `1000^(@)C`
`CaC_(2)+N_(2)overset(1000^(@)C)rarrCaNCN+C`
It is used in large amounts as a nitrogenous fertillizer as it is converted by water in the soil into ammonia.
`CaNCN+5H_(2)OrarrCaCO_(3)+2NH_(4)OH`
It is used as a source of organic chemicals such as melamine.
