Will the double displacement reactions below actually occur? Why or why not? Can a double displacement reaction occur if both products are aq???

All of these are solubility equilibria, in the first case driven by the formation of insoluble $A g C l$.....

Explanation:

$N a C l \left(a q\right) + A g N {O}_{3} \left(a q\right) \rightarrow A g C l \left(s\right) \downarrow + N a N {O}_{3} \left(a q\right)$

Silver chloride precipitates as a curdy, white solid.

$B a {\left(N {O}_{3}\right)}_{2} \left(a q\right) + 2 K C l \left(a q\right) r i g h t \le f t h a r p \infty n s B a C {l}_{2} \left(a q\right) + 2 K N {O}_{3} \left(a q\right)$

Here, the equilibrium mixture would simply contain $B {a}^{2 +}$, ${K}^{+}$, $N {O}_{3}^{-}$, and $C {l}^{-}$ ions......

And likewise for the last reaction.....

$L {i}_{2} S {O}_{4} \left(a q\right) + 2 N {H}_{4} N {O}_{3} \left(a q\right) \rightarrow 2 L i N {O}_{3} \left(a q\right) + {\left(N {H}_{4}\right)}_{2} S {O}_{4} \left(a q\right)$

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