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

Before a vaccine is licensed in the USA, the Food and Drug Administration (FDA) reviews it for safety and effectiveness. The CDC then reviews all studies again, as well as the American Academy of Pediatrics and the American Academy of Family Physicians.
