    Question

    Which reaction represents the correct method of

    extracting iron from its ore in a blast furnace?
    A FeтВВOтВГ + 3C тЖТ 2Fe + 3CO Correct Answer Incorrect Answer
    B FeтВВOтВГ + 3CO тЖТ 2Fe + 3COтВВ Correct Answer Incorrect Answer
    C FeO + COтВВ тЖТ Fe + CO Correct Answer Incorrect Answer
    D FeS + OтВВ тЖТ Fe + SOтВВ Correct Answer Incorrect Answer

    Solution

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