Question 3 1 pts

Write the complete ionic equation for:Pb(NO₃)₂(aq) + 2KCl(aq)-->PbCl₂(s) + 2KNO₃(aq)

Pb2+(aq) + 2NO3-(aq) + 2K+(aq) + 2Cl-(aq) -> PbCl2(s) +2K+(aq) + 2NO3-(aq)

Pb2+(aq) + 2NO3-(aq) + 2K+(aq) + 2Cl-(aq) -> Pb2+(aq) +2NO3-(aq) + 2KCl(aq)

Pb2+(aq) + 2NO3-(aq) + 2K+(aq) + 2Cl-(aq) -> Pb2+(aq) +2Cl-(aq) + 2KNO3-(aq)

Pb2+(aq) + 2NO3-(aq) + 2K+(aq) + 2Cl-(aq) -> Pb2+(aq) +2Cl-(aq) + 2K+(aq) + 2NO3-(aq)
