A) \[N{{a}_{2}}C{{O}_{3}}\]
B) \[{{K}_{2}}C{{O}_{3}}\]
C) \[Ca{{(HC{{O}_{3}})}_{2}}\]
D) \[CaC{{O}_{3}}\]
Correct Answer: D
Solution :
The given compound x must be \[CaC{{O}_{3}}\]. It can be explained by following reactions, \[\underset{\text{(x)}}{\mathop{CaC{{O}_{3}}}}\,\xrightarrow{\Delta }\underset{\text{Residue}}{\mathop{CaO}}\,+C{{O}_{2}}\uparrow \]; \[CaO+{{H}_{2}}O\to \underset{\text{(y)}}{\mathop{Ca{{(OH)}_{2}}}}\,\] \[Ca{{(OH)}_{2}}+C{{O}_{2}}+{{H}_{2}}O\to \underset{\text{z}}{\mathop{Ca(HC{{O}_{3}})}}\,\] \[Ca{{(HC{{O}_{3}})}_{2}}\xrightarrow{\Delta }\underset{\text{(x)}}{\mathop{CaC{{O}_{3}}}}\,+C{{O}_{2}}\uparrow +{{H}_{2}}O\]You need to login to perform this action.
