Em tham khảo nha:

\(\begin{array}{l}
a)\\
(1)\,2Na + 2{H_2}O \to 2NaOH + {H_2}\\
(2)\,2{H_2} + {O_2} \xrightarrow{t^0}  2{H_2}O\\
(3)\,CaO + {H_2}O \to Ca{(OH)_2}\\
(4)\,CuO + CO \xrightarrow{t^0} Cu + C{O_2}\\
(5)\,2Cu + {O_2}\xrightarrow{t^0} 2CuO\\
b)\\
(6)\,CuO + {H_2} \xrightarrow{t^0} Cu + {H_2}O\\
(7)\,3S + 2{H_2}O \to 2{H_2}S + S{O_2}\\
(8)\,2S{O_2} + {O_2} \xrightarrow{t^0,V_2O_5} 2S{O_3}\\
(9)\,S{O_3} + {H_2}O \to {H_2}S{O_4}\\
(10)\,Zn + {H_2}S{O_4} \to ZnS{O_4} + {H_2}
\end{array}\)
