B)  \[2NaHC{{O}_{3}}\xrightarrow{\Delta }N{{a}_{2}}C{{O}_{3}}+{{H}_{2}}O+C{{O}_{2}}\]

C)  \[\begin{align}   & 2NaHC{{O}_{3}}+{{H}_{2}}S{{O}_{4}}\xrightarrow{{}}N{{a}_{2}}S{{O}_{4}} \\  & +2{{H}_{2}}O+2C{{O}_{2}} \\ \end{align}\]

D)  \[\begin{align}   & \text{CaC}{{\text{O}}_{\text{3}}}\text{+}{{\text{H}}_{\text{2}}}\text{S}{{\text{O}}_{\text{4}}}\xrightarrow{{}}\text{CaS}{{\text{O}}_{\text{4}}} \\  & \text{+}{{\text{H}}_{\text{2}}}\text{O+C}{{\text{O}}_{\text{2}}} \\ \end{align}\]
