Many metals occur naturally as sulfide compounds, including CuS 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 smelting. Consider the reaction of zinc sulfide with oxygen to form zinc oxide and sulfur dioxide. First write an unbalanced equation for this reaction. Then, how many kilograms of zinc sulfide are reacted when 256 kilograms sulfur dioxide of is processed by this process? How many kilomoles of oxygen are used up?

ZnS + O2 -> Zn + SO2
Molar mass of SO2 = 64
Molar mass of ZnS = 97
64 g of SO2 are produced by 97 g of ZnS
so, 256 kg of SO2 comes from = 388 kg of ZnS
4 kilomoles of O2 are used up.
