Hydrofluoric acid solutions cannot be stored in glass containers because HF reacts readily with silica dioxide in glass to produce hexafluorosilicic acid ( H2 SiF6 ). SiO2( s) 6 HF(aq) →H2 SiF6(aq) 2 H2 O(l) 40.0  g SiO2 and 40.0  g HF react to yield 45.8  g H2 SiF6 a. What is the limiting reactant? b. What is the mass of the excess reactant? c. What is the theoretical yield of H2 SiF6 ? d. What is the percent yield? | Numerade
