1. (10) The separation of zinc metal from its parent rock requires that it be heated. Sulphide contaminants in these rocks are also combusted and form sulphur dioxide. Sulphur dioxide then reacts with water in the atmosphere to produce $${\mathrm{H}}_2{\mathrm{SO}}_4$$, the main cause of acid rain. Using the equations below (unbalanced), how many moles of sulphuric acid are produced if $$12,500\mathrm{kg}$$ of the original sulphide are combusted? $$\begin{array}{c}\mathrm{ZnS}(\mathrm{s})+\dots {\mathrm{O}}_2(\mathrm{g})?\_\mathrm{ZnO}(\mathrm{s})+\dots {\mathrm{SO}}_2(\mathrm{g})\\ ?{\mathrm{SO}}_2(\mathrm{g})+\_{\mathrm{H}}_2\mathrm{O}(\mathrm{l})?\_{\mathrm{H}}_2{\mathrm{SO}}_3(\mathrm{aq})\\ {\mathrm{H}}_2{\mathrm{SO}}_3(\mathrm{aq})+\_{\mathrm{O}}_2(\mathrm{g})?\_{\mathrm{H}}_2{\mathrm{SO}}_4(\mathrm{aq})\end{array}$$
