Step-by-step explanation:
a) The balanced chemical reaction equation is;
2 LiOH + K2S ------> Li2S + 2 KOH
b) If we include the states of matter then we have;
2 LiOH(aq) + K2S(aq) -----> Li2S(s) + 2 KOH(aq)
c) Complete ionic equation;
2Li^+(aq) + 2OH^-(aq) + 2K^+(aq) + S^+(aq) ----> Li2S(s) + 2K^+(aq) + 2OH^-(aq)
Net ionic equation;
2Li^+(aq) + S^2-(aq) -----> Li2S(s)
