(e) K= [Fe2O3][SO3]^2 all divided by [O2]^9/2 [FeS]^2
3. 0.000042
(b) 116.3g (there is supposed to be 1.00g of unknown base to start with, but this was unfortunately left out of the question)
4. BaS is 0.00075. Cs in Cs2S is 0.010. S in Cs2S is 0.0052

(c) Temperature up, catalyst present. Increase conc. if solution. Increase pressure if gas. Increase surface area if solid.
8. (a) 2.77
(b) H+ + F- --> HF, OH- + HF --> H2O + F-
(c) Na+ + H2O --> NaOH + H+ but this reaction lies infinitely to the left because NaOH, being a strong base, will never form.
