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

Hydrofluoric acid, HF (a q), cannot be stored in glass bottles because compounds called silicates in the glass are attacked by the HF(a q). Sodium silicate (Na2 SiO3), for example, reacts as follows: Na2 SiO3(s) 8 HF(a q) ⟶(a q) 2 NaF(a q) 3 H2 O(l) (a) How many moles of HF are needed to react with 0.300  mol of Na2 SiO3 ? (b) How many grams of NaF form when 0.500  mol of HF reacts with excess Na2 SiO3 ? (c) How many grams of Na2 SiO3 can react with 0.800  g of HF ? | Numerade
