Find A, B and C in the following reactions: NH_3+ A + CO_2 →( NH_4)_2 CO_3; ( NH_4)_2 CO_3+ H_2 O + B → NH_4 HCO_3; NH_4 HCO_3+ NaCl → NH_4 Cl + C
Find $\displaystyle \mathrm{A}, \mathrm{B}$ and C in the following reactions :
$$\begin{aligned}
& \mathrm{NH}_3+\mathrm{A}+\mathrm{CO}_2 \rightarrow\left(\mathrm{NH}_4\right)_2 \mathrm{CO}_3 \\
& \left(\mathrm{NH}_4\right)_2 \mathrm{CO}_3+\mathrm{H}_2 \mathrm{O}+\mathrm{B} \rightarrow \mathrm{NH}_4 \mathrm{HCO}_3 \\
& \mathrm{NH}_4 \mathrm{HCO}_3+\mathrm{NaCl} \rightarrow \mathrm{NH}_4 \mathrm{Cl}+\mathrm{C}
\end{aligned}
$$
Official answer
(3)
