Complete ionic equation:
Ba(NO3)2 (aq) + Na2CrO4 (aq) => 2NaNO3 (aq) + BaCrO4 (s) (Now just break up all of the aqueus compounds)
Ba2+ + 2NO3- + 2Na+ + CrO42- => 2Na+ + 2NO3- + BaCrO4
The spectator ions are Na+ and NO3-.
Net ionic equation:
Ba 2+ (aq) + CrO4 2- (aq) => BaCrO4 (s)

Ba(NO3)2 + Na2CrO3 ===> BaCrO3 + 2 NaNO3
The ionic equation is:
Ba+2 + 2 NO3- + 2 Na+ + CrO3-2 ====>
BaCrO3 + 2 Na+ + 2 NO3-
but the sodium nitrate is soluble, so it remains as sodium ions and nitrate ions (these are your spectator ions), so the net ionic reaction is:
Ba+2 + CrO3-2 ====> BaCrO3 (s)

Ba +2NO3 + 2Na + CrO4 ----> Ba + CrO4 + 2Na +NO3
spectator ions are those that don't participate. They are those that don't precipitate......... Na, and NO3
Net Ionic equation is........ Ba + CrO4 ----> BaCrO4
