Consider the reaction of gold with aqua regia. \[ -\mathrm{Au}(\mathrm{s})+_{-} \mathrm{NO}_{3}^{-}(\mathrm{aq})+{ }_{-} \mathrm{Cl}^{-}(\mathrm{aq})+{ }_{-} \mathrm{H}^{+}(\mathrm{aq}) \rightarrow_{-} \mathrm{AuCl}_{4}^{-}(\mathrm{aq})+{ }_{-} \mathrm{N}_{2}(\mathrm{~g})+{ }_{-} \mathrm{H}_{2} \mathrm{O}(\mathrm{a}) \] What are the stoichiometric coefficients for this reaction? \[ \begin{array}{l} 1,2,4,12,1,1,6 \\ 2,4,8,24,2,2,12 \\ 10,6,40,36,10,3,18 \\ 12,8,48,48,12,4,24 \\ 14,8,52,48,14,4,24 \end{array} \]
