You're right. Since Ag is below Cu in the activity series, Ag will not displace Cu ions. Here is the way you write that.
Ag(s) + Cu(NO3)2(aq) ==> no reaction [or you can write NR and most chemists understand that means no reaction.]
If a silver wire is placed in a beaker containing 1 M Cu(NO3)2, what will happen?
I don't think anything will happen, but what is the right way to explain this is chemical terms?

Thank you!
Can you further explain the significance of the placement of Ag relative to Cu in the activity series and the effect on displacing the Cu^(2+) ions in the Cu(NO3)2 solution? Or where could I find information regarding this topic?

Here is a fairly complete list of the activity series. As you can see it is simply a listing of metals with the most active at the top and the least active at the bottom. Here's how it works. But first, here is the table.

Any metal will displace a metal ion from solution if the metal is above the metal ion. For example,
Al(s) + Cu(NO3)2(aq) ==> Ag(NO3)2(aq) + Cu(s) (you balance) OR
Na(s) + H2O(l) ==> NaOH(aq) + H2(g) (you balance; also, I know H in H2O is not a metal but H is placed in this table so one can tell which metals will generate hydrogen gas from an acid.) Like this,
Zn(s) + 2HCl(aq) ==> ZnCl2(aq) + H2(g)
BUT
Cu + HCl ==> no reaction because Cu is below H in the activity series.and
Cu(s) + Hg(NO3)2(aq) ==> Hg(l) + Cu(NO3)2(aq)
but
Hg(l) + Cu(NO3)2(aq) ==> NR

DrBob, for your first example should that be Al(NO3)2 or Ag(NO3)2? Because you have Al on the reactant side.
