Chapter 9, Problem 83AP

Interpretation Introduction

Interpretation:

The mass of sulphur dioxide produced should be calculated.

Concept Introduction:

The unbalanced equation for roasting reaction of zinc is as follows:

$\text{ZnS}\left(\text{s}\right)+{\text{O}}_{\text{2}}\left(\text{g}\right)\to \text{ZnO}\left(\text{s}\right)+{\text{SO}}_{\text{2}}\left(\text{g}\right)$

The mass of sulphur dioxide produced can be calculated from its number of moles and the number of moles produced depends on the number of moles of ZnS react in the chemical reaction.
