Total: 36
Name the substance oxidised and the substance reduced, and also identify the oxidising agent and reducing agents in the following reaction :
(a) 3MnO2+4Al3Mn+2Al2O3
(b) Fe2O3+3CO2Fe+3CO2
(c) SO2+2H2S3S+2H2O
Solution:  
Substance oxidised =Al
Substance reduced =MnO2
Oxidising agent =MnO2
Reducing agent =Al
Substance oxidised =CO
Substance reduced =Fe2O3
Oxidising agent =Fe2O3
Reducing agent =CO
Substance oxidised =H2S
Substance reduced =SO2
Oxidising agent =SO2
Reducing agent =H2S
