Cân bằng PTHH:

\(C_xH_yO_z+O_2\underrightarrow{t^o}CO_2+H_2O\)

\(C_xH_yO+O_2\underrightarrow{t^o}CO_2+H_2O\)

\(Fe_xO_y+H_2SO_{4\left(đ\right)}\underrightarrow{t^o}Fe_2\left(SO_4\right)_3+S+H_2O\)

\(Fe_xO_y+HNO_3\rightarrow Fe\left(NO_3\right)_3+N_2O+H_2O\)

P/s: Ai chỉ em cách cân bằng \(x;y\) zới:(( mẹo cân bằng ý m.n:((
