A black precipitate of copper sulfide, CuS, is formed when a solution of Cu(II) chloride, CuCl2, is added to a solution of potassium sulfide, K2S. Which of the following ionic equations for this reaction includes the spectator ions as well?
A) CuCl2(aq) + K2S(aq) → CuS(s) + 2KCl(aq)
B) Cu2+(aq) + Cl22-(aq) + K22+(aq) + S2-(aq) → CuS(s) + K22+(aq) + Cl22-(aq)
C) Cu2+(aq) + 2Cl-(aq) + 2K+(aq) + S2-(aq) → CuS(s) + 2K+(aq) + 2Cl- (aq)
D) Cu2+(aq) + S2-(aq) → CuS(s)
