  1. H2S(aq) + 2KOH(aq) ==> 2H2O(l) + K2S(aq)
    H2S + 2K^+ + OH^- =>2H2O + 2K^+ + S^2-
    Cancel the 2K^+
    The net ionic equation is what remains.

  2. I omitted a coefficient in the overall equation. Also I didn't include aq for each. BUT do you realize you can have an OVERALL ionic equation OR you can have a net ionic equation but you can't have both in the same equation except in a few circumstances.
    H2S + 2K^+ + 2OH^- =>2H2O + 2K^+ + S^2- is the overall ionic equation. The net ionic equation is
    H2S(aq) + 2OH^&-(aq) ==> 2H2O(l) + S^2-(aq)
