All of these are solubility equilibria, in the first case driven by the formation of insoluble #AgCl#.....

#NaCl(aq) +AgNO_3(aq)rarrAgCl(s)darr + NaNO_3(aq)# The precipitate of silver chloride is a white, curdy solid. #Ba(NO_3)_2(aq) + 2KCl(aq) rightleftharpoons BaCl_2(aq) + 2KNO_3(aq)# Here, the equilibrium mixture would simply contain #Ba^(2+)#, #K^+#, #NO_3^-#, and #Cl^-# ions...... The same goes for the previous response. #Li_2SO_4(aq) + 2NH_4NO_3(aq) rarr 2LiNO_3(aq) + (NH_4)_2SO_4(aq)# Here, there is no precipitation of an insoluble substance and the equilibrium mixture comprises lithium, ammonium, nitrate, and sulfate ions in solution.

undefined Yes, a double displacement reaction can occur even if both products are aqueous. It depends on whether the reactants form new compounds with each other, regardless of whether those compounds remain in solution or form precipitates, gases, or other products.
