Answer:
Step-by-step explanation:
The balanced chemical equation for the formation of Fe₂O₃ from iron is:
4Fe + 3O₂ → 2Fe₂O₃
From the equation, we can see that 4 moles of Fe reacts with 3 moles of O₂ to form 2 moles of Fe₂O₃. This means that the mole ratio of Fe to Fe₂O₃ is 4:2, or simply 2:1.
Therefore, for every 2 moles of Fe used in the reaction, 1 mole of Fe₂O₃ is formed. We can use this information to find the number of moles of Fe₂O₃ that can be formed from 3.2 moles of Fe:
3.2 moles Fe x (1 mole Fe₂O₃ / 2 moles Fe) = 1.6 moles Fe₂O₃
Therefore, 1.6 moles of Fe₂O₃ can be formed by reacting 3.2 moles of iron.
