Sulfur can be separated from lead in the mineral galena, PbS(s), by “roasting” the ore in the presence of oxygen as shown in the following reaction:
         2PbS(s) + 3O2(g) → 2PbO(s) + 2SO2(g)
Calculate ΔS° for this reaction using the thermodynamic data provided below.
         
 
S°(J/K·mol)
PbS(s)  
     91.2
O2(g)  
   205.0
PbO(s)  
     69.45
SO2(g)  
   248.5
 

◦ –410 J/K·mol
◦ –161.5 J/K·mol
◦ –47.7 J/K·mol
◦ 21.8 J/K·mol
◦ 43.5 J/K·mol

Did you know?

It is believed that the Incas used anesthesia. Evidence supports the theory that shamans chewed cocoa leaves and drilled holes into the heads of patients (letting evil spirits escape), spitting into the wounds they made. The mixture of cocaine, saliva, and resin numbed the site enough to allow hours of drilling.

Did you know?

The first war in which wide-scale use of anesthetics occurred was the Civil War, and 80% of all wounds were in the extremities.

There are approximately 3 million unintended pregnancies in the United States each year.
