Question

I just need to know the net ionic equation and balance them. I figured the equation. but the net and balance is harder.

Co(NO3)2 (aq) + NaOH (aq) = CoOH (s) + Na(NO3)2 (aq)

Co(NO3)2 (aq) + Na2CO3 (aq) = CoCO3 (s) + Na2(NO3)2 (aq)

Co(NO3)2 (aq) + Na3PO4 (aq) = CoPO4 (s) + Na3(NO3)2 (aq)

Cu(NO3)2 (aq) + NaOH (aq) = CuOH (s) + Na(NO3)2 (aq)

Cu(NO3)2 (aq) + NaI (aq) = CuI (s) + Na(NO3)2 (aq)

Cu(NO3)2 (aq) + Na3PO4 (aq) = CuPO4 (s) + Na3(NO3)2 (aq)

Fe(NO3)3 (aq) + NaOH (aq) = FeOH (s) + Na(NO3)3 (aq)

Fe(NO3)3 (aq) + Na2CO3 (aq) = FeCO3 (s) + Na2(NO3)3 (aq)

Fe(NO3)3 (aq) + NaI (aq) =FeI (s) + Na(NO3)3 (aq)

Ba(NO3)3 (aq) + Na3PO4(aq) = BaPO4 (s) + Na3(NO3)3 (aq)
