Many metals occur naturally as sulfide compounds: examples include ZnS and CoS. Air pollution often accompanies the processing of these ores, because toxic sulfur dioxide is released as the ore is converted from the sulfide to the oxide by roasting (smelting). For example, consider the unbalanced equation for the roasting reaction for zinc:

:math> ZnS ( s ) + O 2 ( g ) ZnO ( s ) + SO 2 ( g )

w many kilograms of sulfur dioxide are produced when 1.0 × 10 2 kg of ZnS is roasted in excess oxygen by this process?

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:

ZnS(s)+O2(g)ZnO(s)+SO2(g)

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.

Explanation

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

ZnS(s)+O2(g)ZnO(s)+SO2(g)

Balance the above reaction as follows:

2ZnS(s)+3O2(g)2ZnO(s)+2SO2(g)

From the above balanced chemical reaction, 2 moles of ZnS on reaction with oxygen gives 2 moles of SO2. Here, oxygen is in excess thus, ZnS will be the limiting reactant.

Thus, 1 mol of SO2 gives 1 mol of SO3. The mass of ZnS is given 1×102 kg, number of moles of ZnS can be calculated as follows:

n=mM

Here, m is mass and M is molar mass.

Molar mass of ZnS is 97.47 g/mol, number of moles will be:

n=1×102 kg(1000 g1 kg)97
