When iron metal reacts with oxygen, the reaction can form fe2o3. write a balanced chemical equation for this reaction, and find the number of moles of oxygen that are needed to form 6 mol of fe2o3. show your work.

Balanced equation: 4Fe + 3O₂ → 2Fe₂O₃

Moles of oxygen gas = 9 moles

To answer the question;

4Fe + 3O₂ → 2Fe₂O₃

We are required to determine the number of moles of oxygen needed to form 6 moles of Fe₂O₃.

Therefore; Moles of O₂ = Moles of Fe₂O₃ × 3/2

Hence, moles of oxygen = 6 moles × 3/2

                                         = 9 moles

Thus, Moles of Oxygen needed is 9 moles
