Giái giúp mình bài này với .

Em tham khảo nha:

\(\begin{array}{l}
6)\\
(1)\,2Cu + {O_2} \to 2CuO\\
(2)\,CuO + 2HCl \to CuC{l_2} + {H_2}O\\
(3)\,CuC{l_2} + 2NaOH \to Cu{(OH)_2} + 2NaCl\\
(4)\,Cu{(OH)_2} \to CuO + {H_2}O\\
(5)\,CuO + {H_2}S{O_4} \to CuS{O_4} + {H_2}O\\
8)\\
(1)\,Zn + 2HCl \to ZnC{l_2} + {H_2}\\
(2)ZnC{l_2} + 2NaOH \to Zn{(OH)_2} + 2NaCl\\
(3)\,Zn{(OH)_2} + {H_2}S{O_4} \to ZnS{O_4} + 2{H_2}O\\
(4)\,ZnS{O_4} + Ba{(N{O_3})_2} \to Zn{(N{O_3})_2} + BaS{O_4}\\
(5)\,Zn{(N{O_3})_2} + Mg \to Mg{(N{O_3})_2} + Zn
\end{array}\)
