Cryolite, Na3AlF6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide.

Balance the equation:

Al2O3(s) + NaOH(l) + HF(g) -> Na3AlF6 + H2O(g)

If 14.0 kilograms of Al2O3(s), 57.4 kilograms of NaOh(l), and 57.4 kilograms of HF(g) react completely, how many kilograms of cryolite will be produced?


Which reactants will be in excess?
-Al2O3
-NaOH
-HF

What is the total mass of the excess reactants left over after the reaction is complete?
