Which substance is the oxidizing agent in this reaction? fe2o3+3co→2fe+3co2 express your answer as a chemical formula?
1 answer:
Equation is as follow, Fe₂O₃ + 3 CO → 2 Fe + 3 CO₂Oxidation: 3 CO → 3 CO₂ Oxidation state of C in CO is +2, and that in CO₂ is +4. So, carbon has lost 2 electrons per mole and 6 electrons per 3 moles hence, 3 CO → 3 CO₂ + 6 e⁻Reduction: Fe₂O₃ → 2 Fe Oxidation state of Fe in Fe₂O₃ is +3 per atom, and that in Fe is 0. So, Iron has gained 3 electrons per atom and 6 electrons per 2 atoms hence, Fe₂O₃ + 6e⁻ → 2 FeResult: Iron in Fe₂O₃ has been reduced in this reaction and has played a role of oxidizing agent by oxidizing carbon from +2 state to +4 state.
