Write the balanced net ionic equations for the reactions that occur in each of the given cases as. Cr2(SO4)3(aq) + 3(NH4)2CO3 (aq) = Cr2(CO3)3 ( s) + 3(NH4)2SO4 ( aq) , Ba(NO3)2 (aq)+ k2SO4(aq)=BaSO4(s) + 2KNO3(aq), Fe(NO3)2 (aq) + 2KOH(aq)=2KNO3(aq) + Fe(OH)2 (s)and also Identify the spectator ion or ions in each reaction.
