Question

hydrogen fluoride is one of the few substances that react with glass (which is made of silicon dioxide, sio2 ).

4hf (g) + sio2 (s) → sif5 (g) + 2h2 o (l) .

what mass of hf will react completely with 2.80 mol of sio2 ?

data: mr (hf) = 20.01; mr sio2 = 60.08; mr sif5 = 123.08; mr (h2 o) = 18.01

Hydrogen fluoride is one of the few substances that react with glass (which is made of silicon dioxide,
SiO₂).
4HF (g) + SiO₂ (s) → SiF5 (g) + 2H₂O (1) .
What mass of HF will react completely with 2.80 mol of SiO₂?
Data: Mr (HF) = 20.01; Mr SiO₂ = 60.08; Mr SiF5 = 123.08; Mr (H₂O) = 18.01.
