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 + NaOH + HF = Na3AlF6 + H2O

If 13.8 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? NaOH and/or Al2O3 and/or HF

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

total mass of excess reactants: kg
