A) \[CaC{{O}_{3}}+N{{H}_{3}}\]
B) \[CaHC{{O}_{3}}+N{{H}_{3}}\]
C) \[CaO+N{{H}_{3}}\]
D) \[Ca{{(OH)}_{2}}+N{{H}_{3}}\]
Correct Answer: A
Solution :
Calcium cyanamide and steam reacts as \[\underset{\begin{smallmatrix} Calcium \\ cyanamide \end{smallmatrix}}{\mathop{CaCN}}\,+\underset{Steam}{\mathop{3HOH}}\,\xrightarrow[{}]{{}}CaC{{O}_{3}}+2N{{H}_{3}}\] Thus,\[CaC{{O}_{3}}+N{{H}_{3}}\]is obtained.
