A) \[C{{a}_{3}}{{N}_{2}},N{{H}_{3}}\]
B) \[N{{H}_{3}},C{{O}_{2}}\]
C) \[Ca{{(OH)}_{2}},CaC{{O}_{3}}\]
D) \[N{{H}_{3}},CaC{{O}_{3}}\]
Correct Answer: D
Solution :
\[A=N{{H}_{3}}\]and\[B=CaC{{O}_{3}}\] The reactions are as follows \[3Ca+{{N}_{2}}\xrightarrow{{}}~\underset{calcium\text{ }nitride}{\mathop{C{{a}_{3}}{{N}_{2}}}}\,\] \[C{{a}_{3}}{{N}_{2}}+6{{H}_{2}}O\xrightarrow{{}}3Ca{{(OH)}_{2}}+\underset{(A)}{\mathop{2N{{H}_{3}}}}\,\] \[Ca{{(OH)}_{2}}+\underset{from\,air}{\mathop{C{{O}_{2}}}}\,\xrightarrow{{}}\underset{(B)}{\mathop{CaC{{O}_{3}}}}\,+{{H}_{2}}O\] (Solid layer is due to\[CaC{{O}_{3}}\].)You need to login to perform this action.
