The balanced chemical equation for this reaction is 4 Fe + 3 O 2 --> 2 Fe2O3 Now from the balanced chemical equation we see There are 4 moles of Fe. We also see there are 2 moles of Fe2O3. So their ratio is Fe : Fe2O3 = 4 : 2. Simplifying by diving by 2, we get Fe : Fe2O3 = 2 : 1 dessin de rainbow high a imprimer
