Cryolite, Na3AlF6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide.
AL2O3(s) + NaOH(l) + HF(g) ---> Na3 AlF6 + H2O(g)
1)Balance the equation.
2)If 15.2 kilograms of Al2O3(s), 57.4 kilograms of NaOH(l), and 57.4 kilograms of HF(g) react completely, how many kilograms of cryolite will be produced?
3)Which reactants will be in excess?
4)What is the total mass of the excess reactants left over after the reaction is complete?

The Ostwald process is used commercially to produce nitric acid, which is, in turn, used in many modern chemical processes. In the first step of the Ostwald process, ammonia is reacted with oxygen gas to produce nitric oxide and water. What is the maximum mass of H2O that can be produced by combining 71.8 g of each reactant?
4NH3(g) + 502(g) ---> 4NO(g) + 6H20(g)
4NH3(g) + 502(g) ---> 4NO(g) + 6H20(g)
