A) \[Ca{{(CN)}_{2}}\]and graphite
B) \[Ca\,{{C}_{2}}\]and graphite
C) \[Ca\,C{{N}_{2}}\] and graphite
D) \[Ca\,C{{N}_{2}}\]and\[{{N}_{2}}\]
Correct Answer: C
Solution :
Nitrolim is a mixture of calcium cyanamide and carbon \[(CaC{{N}_{2}}+C).\] It is used as fertilizer. It is prepared when calcium carbide is heated with \[{{N}_{2}}\] at \[\text{1000}{{\,}^{\text{o}}}\text{C}\text{.}\] \[Ca{{C}_{2}}+{{N}_{2}}\xrightarrow{1000{{\,}^{o}}C}\underbrace{CaC{{N}_{2}}+C}_{\text{Nitrolim}}\]
