Answer:

Both #Na^+# and #NO_3^-# will be spectators.

Explanation:

We go back to simple solubility rules. All alkali metals salts are soluble. All nitrates are soluble. All halides are soluble (except for those of #Ag^+# and #Hg_2^(2+)#). All hydroxides are insoluble (except for previous).

So the net ionic equation representing the reaction is:

#Ag^+ + OH^(-) rarr AgOH(s)darr#

Silver hydroxide is not a well-characterized species. Its likely formulation is #Ag_2O*(OH_2)#, a hydrous oxide of silver, but you don't need to know this in 6th form.
