Cryolite, Na3AlF6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide.
THe Balanced equation is:
Al2O3(s) +6 NaOH(l) +12 HF(g) ->2 Na3AlF6 +9H2O(g)
If 11.5 kilograms of Al2O3(s), 50.4 kilograms of NaOH(l), and 50.4 kilograms of HF(g) react completely, how many kilograms of cryolite will be produced?
Which reactants will be in excess?
-Al2O3
-NaOH
-HF
What is the total mass of the excess reactants left over after the reaction is complete?
