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

equation:
Al2O3(s)+NaOH(l)+HF(g)⟶Na3AlF6+H2O( g)

If 17.6 kg of Al2O3(s), 58.4 kg of NaOH(l), and 58.4 kg of HF(g) react completely, how many kilograms of cryolite will be produced?
mass of cryolite produced: kg Na3AlF6

Which reactants will be in excess?
-Al2O3Al2O3
-NaOHNaOH
-HFHF

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