Em tham khảo nha :
\(\begin{array}{l}
(1)Mn{O_2} + 4HCl \to MnC{l_2} + C{l_2} + 2{H_2}O\\
(2)KMn{O_4} + 16HCl \to 5C{l_2} + 2KCl + 2MnC{l_2} + 8{H_2}O\\
(3)C{l_2} + 2KBr \to 2KCl + B{r_2}\\
(4)B{r_2} + 2KI \to 2KBr + {I_2}\\
(5)2Al + 3{I_2} \to 2Al{I_3}\\
(6)C{l_2} + 2NaOH \to NaCl + NaClO + {H_2}O\\
(7)C{l_2} + {H_2} \to 2HCl\\
(8)HCl + AgN{O_3} \to AgCl + HN{O_3}
\end{array}\)
