Help please! I need the Molecular equation, the Complete ionic equation and the Net ionic equation for these 5 chemical reactions. ?

5. cadmium chloride + sodium sulfide

4. potassium chloride + sodium phosphate

3. copper (II) sulfate + sodium phosphate

2. nickel (II) chloride + sodium hydroxide

1. cadmium chloride + silver nitrate

    5. cadmium chloride + sodium sulfide

    CdCl2(aq) + Na2S(aq) --> CdS(s) + 2NaCl(aq)

    Cd^2+ + 2Cl- --> 2Na+ + S^2- --> CdS(s) + 2Na+ + 2Cl-

    Cd^2+ + S^2- --> CdS(s)

    4. potassium chloride + sodium phosphate

    No reaction .... unless you count the formation of KH2PO4 and K2HPO4, but that's a bit more advanced than the elementary reactions you seem to have been given.

    3. copper (II) sulfate + sodium phosphate

    3CuSO4(aq) + 2Na3PO4(aq) --> Cu3(PO4)2(s) + 3Na2SO4(aq)

    3Cu^2+ + 3SO4^2- + 6Na+ + 2PO4^3- --> Cu3(PO4)2(s) + 6Na+ + 3 SO4^2-

    3Cu^2+ + 2PO4^2- --> Cu3(PO4)2(s)

    2. nickel (II) chloride + sodium hydroxide

    Get the idea?  Ni(OH)2 is the insoluble product

    1. cadmium chloride + silver nitrate

    AgCl is the insoluble product

    I will do ONE ---  these are to help you learn solubility rules  ....  give it a try,

    1. cadmium chloride + silver nitrate

         CdCl2  +  2AgNO3  -->  Cd(NO3)2 +  2AgCl

        Cd(2+) aq  +  2Cl(-)aq  +  2Ag(+)aq  +  2NO3(-)aq

          ===>   Cd(2+) aq + 2NO3(-)aq   +  2AgCl(s)

       Cl(-)aq + Ag(+)aq   ==>  AgCl(s)

    Tell me, are you having chemists on YA do your homework so that you can go to some stupid protest?
