I really need these answers to balance the net ionic equation or make it into one. 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) +

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)
