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) + naoh(l) + hf(g) > na3alf6 + h2o(g)
1. if 15.8 kg of al2o3(s), 55.4 kg of naoh(l), and 55.4 kg of hf(g) react completely, how many kilograms of cryolite will be produced?
