Cryolite, Na3AlF6(s),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)Al2O3(s)+NaOH(l)+HF(g)Na3AlF6+H2O(g)

If 10.3 kg of Al2O3(s),10.3 kg of Al2O3(s), 55.4 kg of NaOH(l),55.4 kg of NaOH(l), and 55.4 kg of HF(g)55.4 kg of HF(g) react completely, how many kilograms of cryolite will be produced?

mass of cryolite produced:

kg Na3AlF6kg Na3AlF6

Which reactants will be in excess?
