Question

$CaC_{2}+N_{2} \, \rightarrow A, \, product \, A \, is$

• A. $CaCN_{2}$
• B. $CaCN_{2} \, and \, C$
• C. $CaCN_{2}+N_{2}$
• D. None of these

Answer 1

Answer: (B)

When calcium carbide reacts with nitrogen at $1000\text{℃},$ calcium cyanamide and Carbon are formed.
$\text{CaC}_{2} + \text{N}_{2} \overset{ \, 1000 ℃ \, }{ \rightarrow } \, \underset{\text{calcium cyanamide}}{\text{CaCN}_{2}} + \text{C}$
