A) \[C{{O}_{2}}\] and \[CO\]
B) \[CO\] and \[C{{O}_{2}}\]
C) \[CO\] and \[CO\]
D) \[C{{O}_{2}}\] and \[C{{O}_{2}}\]
Correct Answer: D
Solution :
According to the equation, \[Ca{{(OH)}_{2}}+C{{O}_{2}}\xrightarrow{\Delta }CaC{{O}_{3}}+{{H}_{2}}O\] \[CaC{{O}_{3}}+{{H}_{2}}O+C{{O}_{2}}\xrightarrow{{}}Ca{{(HC{{O}_{3}})}_{2}}\] \[Ca{{(HC{{O}_{3}})}_{2}}\xrightarrow{\Delta }CaO+{{H}_{2}}O+2C{{O}_{2}}\] Hence, the gas A and B are \[C{{O}_{2}}\]and \[C{{O}_{2}}\] respectivelyYou need to login to perform this action.
