Question

please help me last time i asked they didnt do anything and just marked it as solved 

Cryolite, Na, AIF,(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide.
Balance the equation for the synthesis of cryolite.
equation: Al,0,(s) + NaOH(1) + HF(g) → Na,AlF, + H,0(g)
If 15.6 kg of Al,0,(s), 57.4 kg of NaOH(1), and 57.4 kg of HF(g) react completely, how many kilograms of cryolite will
be produced?
kg Naz AIF6
mass of cryolite produced:
Which reactants will be in excess?
HF
NaOH
O Al,O3
What is the total mass of the excess reactants left over after the reaction is complete?
total mass of excess reactants:
kg
