    Answer:

    2 ZnS + 3O2 —> 2ZnO + 2 SO2

    Explanation:

    2 ZnS + 2O2 —> 2ZnO + SO2

    There are 2 Zn atom on the LHS and 2 Zn on the RHS. Hence the Zn is balanced on both sides of the equation.

    There are two S atom on the LHS but there is only one S atom on the RHS.

    Hence we will balance the S atoms

    2 ZnS + 2O2 —> 2ZnO + 2 SO2

    Now the oxygen is unbalanced as there are three oxygen molecule on the RHS but only two on the LHS.

    Hence, the balanced equation would be

    2 ZnS + 3O2 —> 2ZnO + 2 SO2
