Question

Nitrolim is a:

• A. A mixture of calcium cyanide and carbon
• B. A mixture of calcium carbide and nitrogen
• C. A mixture of $N{H}_{4}CN$ and $CaCN$
• D. A mixture of calcium cyanamide and carbon

Answer 1

The correct option is D A mixture of calcium cyanamide and carbon

A mixture of calcium carbide and nitrogen forms calcium cyanamide, not nitrolim.
A blend of calcium cyanamide and carbon is known as nitrolim. At the point when nitrogen is disregarded calcium carbide at a reasonably high temperature, we get a blend called nitrolim which is nitrogenous manure. Calcium cyanamide is a glossy powder used in agriculture as manure, herbicide, pesticide, and a defoliant for cotton plants.
The blend creates a strong blend of calcium cyanamide $\left[Ca\right(CN{)}_2]$ and carbon.
$Ca{C}_2+N_2\to Ca(CN{)}_2+C$
So, the correct answer is “Option B”.
