Question

What volume of SO2, at room temperature and pressure is produced on heating 9.7g

of Zinc Sulphide (ZnS) if reaction takes place as follows
2ZnS()+ 302(g)
→2ZnO(+2SO2(g)
(A) 2.4 dm³
(B) 4.8 dm³
(C) none of these

Answer 1

C. None of these

2 volumes of zinc sulphide produces two volumes of Sulphur dioxide. So, 9.7g of ZnS will produce nothing less than 9.7g of SO2.
