Cryolite, Na 3 AlF 6 ( 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) + 6NaOH (l) + 12HF (g) -> 2Na3AlF6 + 9H2O (g) Al 2 O 3 ( s ) + 6 NaOH ( l ) + 12 HF ( g ) ⟶ 2 Na 3 AlF 6 + 9 H 2 O ( g ) If 15.0 kg of Al 2 O 3 ( s ) , 59.4 kg of NaOH ( l ) , and 59.4 kg of HF ( g ) react completely, how many kilograms of cryolite will be produced? mass of cryolite produced: kg Na 3 AlF 6 Which reactants will be in excess? NaOH HF Al 2 O 3 What is the total mass of the excess reactants left over after the reaction is complete? total mass of excess reactants:
