a . Silica is a name for silicon dioxide, SiO2(s), a chief compo- nent of glass. Silica can react with hydrofluoric acid, HF (aq) to produce silicon tetrafluoride, SiF4(g)" which is a gas at room temperature: SiO268) + 4 HFaq) → SiF.(g) + 2 H,00) ( 4 (a) What mass of silicon tetrafluoride can be produced from 6.80 g of silica? (b) What mass of hydrofluoric acid is required to com- pletely react with 53.2 g of silica? (c) What mass of water is produced when 10.6 g of silica completely reacts in this reaction? CM
