  • question_answer \[BaS{{O}_{4}}\] and carbon on heating reacts to produce [Pb. PMT 2004]

    A) \[Ba+S{{O}_{2}}+C{{O}_{2}}\]

    B) \[BaS+CO\]

    C) \[BaS+{{O}_{2}}+S{{O}_{2}}\]

    D) \[BaC{{O}_{3}}+S+{{O}_{2}}\]

    Correct Answer: B

    Solution :

    \[BaS{{O}_{4}}+4C\xrightarrow{\text{Heat}}BaS+4CO\] Thus, on heating they produce\[BaS+4CO\].
