Question

Cryolite, Na3AlF6 can be synthesized using aluminum oxide. balance karro equation Al2O3(s) + NaOH(l) + HF(g) -> Na3AlF6 + H2O(g) if 12.2 kg of Al2O3(s), 60.4kg of NaOH(l) and 60.4 kg of HF(g) react completely, how many ilograms of cryolite are produced? which reactants are in excess? HF Al2O3 NaOH what is the total mass of the excess reactants left over after the reaction is complete?

Answer 1

50.24 kg of cryolite produced; NaOH and HF are in excess; total mass of excess reactants is 63.38 kg

Answer 2

The balanced equation is: Al2O3(s) + 6NaOH(l) + 12HF(g) → 2Na3AlF6 + 9H2O(g). Al2O3 is the limiting reagent, and the calculations show the amounts of excess reactants and the mass of cryolite produced.
