What is the balanced equation describing the following chemical reaction Solid aluminum metal reacts with solid diatomic iodine to form solid \( \mathrm{Al}_{2} \mathrm{I}_{6} \) Note: Please include state of matter \[ \begin{array}{l} \mathrm{Al}^{3+}(\mathrm{aq})+\mathrm{I}^{\prime}(\mathrm{aq}) \rightarrow \mathrm{All}_{3}(\mathrm{aq}) \\ \mathrm{Al}(\mathrm{s})+\mathrm{I}_{2}(\mathrm{~s}) \rightarrow \mathrm{Al}_{2} \mathrm{I}_{6}(\mathrm{~s}) \\ 2 \mathrm{Al}(\mathrm{s})+6 \mathrm{I}(\mathrm{s}) \rightarrow \mathrm{Al}_{2} \mathrm{I}_{6}(\mathrm{~s}) \\ \mathrm{Al}(\mathrm{s})+\mathrm{I}_{6}(\mathrm{~s}) \rightarrow \mathrm{Al}_{2} \mathrm{I}_{6}(\mathrm{~s}) \\ 2 \mathrm{Al}(\mathrm{s})+3 \mathrm{I}_{2}(\mathrm{~s}) \cdots \mathrm{Al}_{2} \mathrm{I}_{6}(\mathrm{~s}) \end{array} \] Which of the following equations is not balanced? \[ \begin{array}{l} 2 \mathrm{NaHCO}_{3} \rightarrow \mathrm{Na}_{2} \mathrm{CO}_{3}+\mathrm{CO}_{2}+\mathrm{H}_{2} \mathrm{O} \\ 4 \mathrm{NH}_{3}+14 \mathrm{O}_{2} \rightarrow 4 \mathrm{NO}_{2}+6 \mathrm{H}_{2} \mathrm{O} \\ \mathrm{Cr}_{2}\left(\mathrm{SO}_{4}\right)_{3}+6 \mathrm{KOH} \rightarrow 2 \mathrm{Cr}(\mathrm{OH})_{3}+3 \mathrm{~K}_{2} \mathrm{SO}_{4} \end{array} \] none of the other possible answers \[ 2 \mathrm{Cr}+6 \mathrm{HCl} \rightarrow 2 \mathrm{CrCl}_{3}+3 \mathrm{H}_{2} \]
