2. a) Balance the equation below and use it to calculate the moles of Fe formed from \(0.50\) moles of \(\mathrm{Fe}_{2} \mathrm{O}_{3}:\)
$$ \mathrm{Fe}_{2} \mathrm{O}_{3}(\mathrm{~s})+\mathrm{CO}(\mathrm{g}) \stackrel{\Delta}{\rightarrow} \mathrm{Fe}(\mathrm{s})+\mathrm{CO}_{2}(\mathrm{~g}) $$
3. Balance the equation below then calculate the mass of \(\mathrm{ZnCl}_{2}\) by obtained by reacting \(10.0 \mathrm{~g}\) of zinc metal with an excess (more than is required) of hydrochloric acid
$$ \mathrm{Zn}(\mathrm{s})+\mathrm{HCl}(\mathrm{aq}) \rightarrow \mathrm{ZnCl}_{2}(\mathrm{aq})+\mathrm{H}_{2}(\mathrm{~g}) $$
