Hydrofluoric acid solutions cannot be stored in glass containers because hf reacts readily with silica dioxide in glass to produce hexafluorosilicic acid (h2sif6).
sio2(s) + 6 hf(aq) h2sif6(aq) + 2 h2o(l)
21.0 g sio2 and 70.5 g of hf react to yield 45.8 g h2sif6.
(a) what is the limiting reactant?
hf
or
sio2
(b) what is the mass of the excess reactant?
g
(c) what is the theoretical yield of h2sif6?
g
(d) what is the percent yield?
%
