Em tham khảo nha:
\(\begin{array}{l}
CaC{O_3} \xrightarrow{t^0} CaO + C{O_2}\\
A:CaO\\
P:C{O_2}\\
CaO + {H_2}O \to Ca{(OH)_2}\\
B:{H_2}O\\
C:Ca{(OH)_2}\\
Ca{(OH)_2} + 2HCl \to CaC{l_2} + 2{H_2}O\\
D:HCl\\
E:CaC{l_2}\\
CaC{l_2} + {K_2}C{O_3} \to CaC{O_3} + 2KCl\\
C{O_2} + NaOH \to NaHC{O_3}\\
X:NaOH\\
Q:NaHC{O_3}\\
2NaHC{O_3} + 2KOH \to {K_2}C{O_3} + N{a_2}C{O_3} + 2{H_2}O\\
Y:KOH\\
R:N{a_2}C{O_3}\\
N{a_2}C{O_3} + Ca{(N{O_3})_2} \to CaC{O_3} + 2NaN{O_3}\\
Z:Ca{(N{O_3})_2}
\end{array}\)
