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

Question

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)

Answer 1

Na2CO3 ( ) + Co(NO3)2 ( ) --> 2NaNO3 ( ) + CoCO3 ( ) complete ionic equation And net ionic equation
