CHEMISTRY 1414 Fall 2011 Practice Problem Set #5 Question 1 The “roasting” of metal sulfides in air yields the corresponding oxides, but is a significant source of pollution. Lead sulfide is converted to the oxide as follows: PbS ( s ) + O 2 ( g ) Æ PbO ( s ) + SO 2 ( g ) a) . If 655 g of lead(II) sulfide is used, how many grams of oxygen are required to completely consume this amount if lead(II) sulfide? b) . Again using the If 655 g of lead(II) sulfide, what yield of lead(II) oxide and sulfur dioxide will be produced? c) . The pollution from this process is acid rain, which is produced according to the following two equations: SO 2 ( g ) + O 2 ( g ) Æ SO 3 ( g ) SO 3 ( g ) + H 2 O ( l ) Æ H 2 SO 4 ( aq ) If 75.78 g of PbS is burned in excess oxygen, what is the maximum amount in grams of sulfuric acid that can be produced?
