Giúp mik nha xin luôn ó

Em tham khảo nha:

\(\begin{array}{l}
1)\\
2{C_x}{H_y} + \dfrac{{4x + y}}{2}{O_2} \xrightarrow{t^0} 2xC{O_2} + y{H_2}O\\
2)\\
2F{e_x}{O_y} + \dfrac{{3x - 2y}}{2}{O_2} \xrightarrow{t^0} xF{e_2}{O_3}\\
3)\\
F{e_x}{O_y} + y{H_2} \xrightarrow{t^0}xFe + y{H_2}O\\
4)\\
3F{e_x}{O_y} + 2yAl \xrightarrow{t^0} 3xFe + yA{l_2}{O_3}\\
5)\\
2F{e_x}{O_y} + (y - x)C \xrightarrow{t^0} 2xFeO + (y - x)C{O_2}\\
6)\\
3F{e_x}{O_y} + (y - x)Al \xrightarrow{t^0} 3xFeO + (y - x)A{l_2}{O_3}
\end{array}\)
