Burning coal and oil in a power plant produces pollutants such as sulfur dioxide, $${\mathrm{SO}}_2$$. The sulfi containing compound can be removed from other waste gases by the following reaction: $$2{\mathrm{SO}}_2(\mathrm{g})+2{\mathrm{CaCO}}_3(\mathrm{s})+{\mathrm{O}}_2(\mathrm{g})?2{\mathrm{CaSO}}_4(\mathrm{s})+2{\mathrm{CO}}_2(\mathrm{g})$$ $$\begin{array}{llllll}[\text{ [Molar masses: }& 64.07& 100.1& 32.00& 136.2& 44.01\end{array}]$$ (a) Name the compounds involved in the reaction. (b) What mass of $${\mathrm{CaCO}}_3$$ is required to remove $$155\mathrm{g}$$ of $${\mathrm{SO}}_2$$ ? (c) What mass of $${\mathrm{CaSO}}_4$$ is formed when $$155\mathrm{g}{\mathrm{SO}}_2$$ is consumed completely?
