    Flux is often added to remove impurities from an iron ore in a blast furnace. In the reactions slag and flux are

    A) \[CaSi{{O}_{3}}\] and \[Si{{O}_{2}}\]

    B) \[CaO\] and \[Si{{O}_{3}}\]

    C) \[CaSi{{O}_{3}}\] and \[CaO\]

    D) \[Si{{O}_{2}}\] and \[CaSi{{O}_{3}}\]

    Correct Answer: C

    Solution :

    [c] \[CaC{{O}_{3}}\to CaO+C{{O}_{2}}\] \[\underset{(flux)}{\mathop{CaO}}\,+\underset{(impurity)}{\mathop{Si{{O}_{2}}}}\,\to \underset{(slag)}{\mathop{CaSi{{O}_{3}}}}\,\]
