How would you write an ionic equasion combining K2CrO4 with Ba(No)?

Question

As well as K2Cro4 with Ca(No3)2...

Answer 1

The complete ionic equation would be:
2 K+(aq) + CrO42-(aq) + Ca2+(aq) + 2 NO3-(aq) --> CaCrO4(s) + 2 K+(aq) + 2 NO3-(aq)

To get the net ionic equation, just remove the K+ and NO3- from both sides, since they are spectator ions.
