What is the mole ratio between CuCl2 and NaNO3?

If this is a double replacement reaction or salt metathesis, then I have taken the liberty of including the symbol representing an aqueous solution, (aq), to the formulas in the equation written as CuCl2 (aq) + 2NaNO3 (aq) →Cu (NO3) 2 (aq) + 2NaCl (aq).

In order for a double replacement reaction to occur, one of the products must be a solid precipitate (a salt), an insoluble gas, or water. Since all species are in aqueous solution, none of these products occur, which means there is no reaction. The result is an aqueous solution containing Cu2+, Cl-, Na+, and NO3 - ions.

The equation should be written as CuCl2 (aq) + 2NaNO3 (aq) →No Reaction
