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(s)+6NaOH(i)+12HF(g)2Na3AlF6+9H2O(g) If 10.3kg of Al2O3(s),55.4kg of NaOH(l), and 55.4kg of HF(g) react completely, how many kilograms of cryolite will be produced? mass of cryolite produced: Which reactants will be in excess? HF NaOH Al2O5 What is the total mass of the excess reactants left over after the reaction is complete? total mass of excess reactants
