4 Fe (S) + 3 O2 (g) ---------> 2Fe2O3 (s),
In this reaction the Fe has 0 oxidation state, and in Fe2O3 IRON HAS +3 oxidation state , that is Fe is oxidised here and O2 has oxidation state of 0 and which has changed in Fe2o3 to -2 , that is oxygen is reduced here.
The reaction is oxidising reaction , here the oxygen is oxidising agent( itself reduced), and Fe is reducing agent (itself oxidised).
4 Fe (S) + 3 O2 (g) ---------> 2Fe2O3 (s),
0 0 +3 -2
