A) \[CaC{{N}_{2}}\]
B) \[CaC{{N}_{2}}\]and\[C\]
C) \[CaC{{N}_{2}}+{{N}_{2}}\]
D) None of these
Correct Answer: B
Solution :
When calcium carbide reacts with nitrogen at\[{{1000}^{o}}C\], calcium cyanamide and carbon is formed. \[Ca{{C}_{2}}+{{N}_{2}}\xrightarrow{{{1000}^{o}}C}\underset{calcium\,\,cyanamide}{\mathop{CaC{{N}_{2}}}}\,+C\]
