Chlorine gas can be made from the reaction of manganese dioxide with hydrochloric acid. What is the theoretical yield of \( \mathrm{Cl}_{2} \) when \( 28 \mathrm{~g} \) of \( \mathrm{MnO}_{2} \) are mixed with \( 42 \mathrm{~g} \) of \( \mathrm{HCl} \) ? \( \mathrm{MnO}_{2}(\mathrm{~s})+4 \mathrm{HCl}(\mathrm{aq}) \rightarrow \mathrm{MnCl}_{2}(\mathrm{aq})+2 \mathrm{H}_{2} \mathrm{O}(\mathrm{I})+\mathrm{Cl}_{2}(\mathrm{~g}) \) \( 5.40 \mathrm{~g} \) \( 20.42 \mathrm{~g} \) \( 21.60 \mathrm{~g} \) \( 22.83 \mathrm{~g} \) \( 34.33 \mathrm{~g} \) \( 81.67 \mathrm{~g} \) \( 86.39 \mathrm{~g} \)
