half equations are
Cu ==> Cu^2+ + 2e
Ag^+ e ==>Ag
--------------------------
then
Cu ==> Cu^2+ + 2e
2(Ag^+ e ==>Ag)
------------------------
Cu + 2Ag^+ + 2e ==> Cu^2+ + 2e + 2Ag
then cancel 2e and add NO3^-
Cu + 2Ag^+ + 2e ==> Cu^2+ + 2e + 2Ag
NO3^- ==> NO3^-
----------------------------------
Cu + 2AgNO3 ==> Cu(NO3)2 + 2Ag
Write half equation s for the following reaction.
Cu(s)+2AgNO3(aq) produces Cu(NO3)2(aq)+2Ag.
