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. for example consider the unbalanced equation : ZnS(s)+O2 (g)= ZnO(s)+ SO2 (g). how many kilograms of sulfur dioxide are produced when 610 kg of ZnS is roasted in excess oxygen by this process?
