QUESTION:

Calcium oxide (CaO) is used to remove sulfur dioxide generated by coal-burning power stations:

\(2 \mathrm{CaO}(\mathrm{s})+2 \mathrm{SO}_{2}(\mathrm{g})+\mathrm{O}_{2}(\mathrm{g}) \rightarrow 2 \mathrm{CaSO}_{4}(\mathrm{s})\)

Calculate the enthalpy change for this process if \(6.6 \times 10^{5}\ \mathrm{g}\) of \(\mathrm{SO}_{2}\) are removed by this process every day.
