How can I write the equations for the following acid-base reactions and predict (by checking values) which side the equilibrium prefers? Protons to be moved will be labled in parenthesis. This is for organic chemistry a) KOCH3 + HCN (H in HCN)

b) CH3OH (last H in CH3OH) + NaNH2

c) HCOOH (last H in HCOOH) + NaOH
