A) \[\operatorname{CaS}{{O}_{4}}-2{{H}_{2}}O\]
B) \[CaC{{O}_{3}}\]
C) \[N{{a}_{2}}C{{O}_{3}}\]
D) \[{{K}_{2}}C{{O}_{3}}\]
Correct Answer: B
Solution :
\[\underset{A}{\mathop{CaC{{O}_{3}}}}\,\,(s)\xrightarrow{\Delta }\,\,CaO\,\,+\,\,C{{O}_{2}}\uparrow \] \[CaO+{{H}_{2}}O \xrightarrow{{}} \underset{B}{\mathop{Ca{{\left( OH \right)}_{2}}}}\, \xrightarrow{2C{{O}_{2}}}\,\,\underset{C}{\mathop{Ca{{\left( HC{{O}_{3}} \right)}_{2}}}}\,\]\[\underset{C}{\mathop{\operatorname{Ca}{{\left( HC{{O}_{3}} \right)}_{2}}}}\,\,\xrightarrow{\Delta }\,\,\underset{A}{\mathop{CaC{{O}_{3}}}}\, + C{{O}_{2}} + {{H}_{2}}O\]You need to login to perform this action.
