(i) Determine whether each species in the following equations is acting as a Bronsted acid or base, and label it. (ii) Indicate whether the equilibrium lies to the left or to the right, (iii) Estimate K for each equation if possible.
(a) H2O + HCN ⇌ H3O+ + CN-
(b) CH3O- +NH3 ⇌ CH3OH + NH2-
(c) HF + CH3COO- ⇌ F- + CH3COOH
(d) CH3- + NH3 ⇌ CH4 + NH2-
(e) H3O+ + CI- ⇌ H2O + HCI
(f) CHCOOH + CH3S ⇌ CH3COO- + CH3SH
