Book Free Demo1. There are four types of reactions given
\(Fe_2O_3\) + \(2Al\) \(\xrightarrow[]{Heat}\) \(2Fe\) + \(Al_2O_3\)
\(CuO\) + \(H_2\) \(\xrightarrow[]{}\) \(Cu\) + \(H_2O\)
\(H_2S\) + \(SO_2\) \(\xrightarrow[]{}\) \(3S\) + \(2H_2O\)
\(Mg\) + \(O_2\) \(\xrightarrow[]{}\) \(MgO\)
The reducing agents in I & II and oxidizing agents in III & IV are
