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
