    Question

    Which reaction represents the correct method of

    extracting iron from its ore in a blast furnace?
    A Fe₂O₃ + 3C → 2Fe + 3CO Correct Answer Incorrect Answer
    B Fe₂O₃ + 3CO → 2Fe + 3CO₂ Correct Answer Incorrect Answer
    C FeO + CO₂ → Fe + CO Correct Answer Incorrect Answer
    D FeS + O₂ → Fe + SO₂ Correct Answer Incorrect Answer

    Solution

    n a blast furnace, iron(III) oxide (Fe₂O₃ ) is reduced by carbon monoxide (CO) to produce iron (Fe) and carbon dioxide (CO₂ ): Fe₂O₃  + 3CO → 2 Fe + 3CO₂ This is the main reduction reaction in the extraction of iron. CO is generated in the furnace from the combustion of coke (carbon).
