    Ans. Both of these compounds are ferrous oxides. Therefore, Fe₂O₃ can be given as a simple oxide, where Fe in Ferric oxide results only +3 in the oxidation state, and hence, Fe₃O₄ is a mixed oxide, where the Fe in Ferrous oxide exists in both +2 and +3 oxidation states. Although, we can compose Fe₃O₄ as FeO. And, Fe₂O₃ can be written as iron oxide (II), whereas, Fe₃O₄ can
