When Mixed, Solutions of Aluminum Nitrate, Al(NO₃)₃, and Ammonium Carbonate $\rightarrow$

Multiple Choice

When mixed, solutions of aluminum nitrate, Al(NO₃) ₃, and ammonium carbonate, (NH₄) ₂CO₃, will form a precipitate of aluminum carbonate, Al₂(CO₃) ₃.The balanced equation is 2Al(NO₃) ₃(aq) + 3(NH₄) ₂CO₃(aq) $\rightarrow$ Al₂(CO₃) ₃ (s) + 6NH₄NO₃(aq) Which of the following statements regarding this reaction is incorrect?

A) 2 moles of Al(NO₃) ₃ will react with 3 moles of (NH₄) ₂CO₃.
B) If 6 moles of (NH₄) ₂CO₃ react with sufficient Al(NO₃) ₃, 2 moles of Al₂(CO₃) ₃ should form.
C) If 0.5 mole of (NH₄) ₂CO₃ react with sufficient Al(NO₃) ₃, 3 moles of Al₂(CO₃) ₃ should form.
D) If 1.5 moles of Al₂(CO₃) ₃ are formed, given sufficient starting materials, then 9 moles of NH₄NO₃ should also form.
E) 4 moles of Al(NO₃) ₃ will react with 6 moles of (NH₄) ₂CO₃.
