giúp mình giải bài này vs ạ mình c.on trc nhé

Em tham khảo nha:

\(\begin{array}{l}
13)\,CaC{l_2} + 2AgN{O_3} \to Ca{(N{O_3})_2} + 2AgCl\\
14)\,4P + 5{O_2} \to 2{P_2}{O_5}\\
15)\,{N_2}{O_5} + {H_2}O \to 2HN{O_3}\\
16)\,Zn + 2HCl \to ZnC{l_2} + {H_2}\\
17)\,2Al + 3CuC{l_2} \to 2AlC{l_3} + 3Cu\\
18)\,C{O_2} + Ca{(OH)_2} \to CaC{O_3} + {H_2}O\\
19)\,S{O_2} + Ba{(OH)_2} \to BaS{O_3} + {H_2}O\\
20)\,2KMn{O_4} \to {K_2}Mn{O_4} + Mn{O_2} + {O_2}
\end{array}\)
