    Heating mixture of \[{{\operatorname{Cu}}_{2}}O and C{{u}_{2}}S\]will give:

    A) \[\operatorname{Cu} + S{{O}_{2}}\]                

    B) \[\operatorname{Cu} + S{{O}_{3}}\]

    C) \[\operatorname{CuO} + CuS\]

    D) \[{{\operatorname{Cu}}_{2}}S{{O}_{3}}\]

    Correct Answer: A

    Solution :

    \[\operatorname{Cu}+S{{O}_{2}}\] \[2C{{u}_{2}}O + C{{u}_{2}}S\xrightarrow{\Delta }6Cu + S{{O}_{2}}\] On heating mixture of\[C{{u}_{2}}O and C{{u}_{2}}S\]will \[\operatorname{give}6U+S{{O}_{2}}\]
