Answer:

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

Explanation:

#NaCl(aq) +AgNO_3(aq)rarrAgCl(s)darr + NaNO_3(aq)#

Silver chloride precipitates as a curdy, white 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......

And likewise for the last reaction.....

#Li_2SO_4(aq) + 2NH_4NO_3(aq) rarr 2LiNO_3(aq) + (NH_4)_2SO_4(aq)#

And here the equilibrium mixture contains, lithium, ammonium, nitrate, and sulfate ions in solution, with no precipitation of an insoluble material.
