A) \[Ca{{(HC{{O}_{3}})}_{2}}\]
B) \[CaC{{O}_{3}}\]
C) \[N{{a}_{2}}C{{O}_{3}}\]
D) \[{{K}_{2}}C{{O}_{3}}\]
Correct Answer: B
Solution :
[b] \[Ca\underset{(X)}{\mathop{C{{O}_{3}}}}\,\to CaO+C{{O}_{2}}\] |
\[CaO+{{H}_{2}}O\to Ca\underset{(Y)}{\mathop{{{(OH)}_{2}}}}\,\] |
\[Ca{{(OH)}_{2}}+2C{{O}_{2}}\to \underset{(Z)}{\mathop{Ca{{(HC{{O}_{3}})}_{2}}}}\,\] |
\[Ca{{(H\underset{(Z)}{\mathop{C}}\,{{O}_{3}})}_{2}}\xrightarrow{\Delta }Ca\underset{(X)}{\mathop{C}}\,{{O}_{3}}+{{H}_{2}}O\] |
