text: pb(no3)2 + agno3  can someone please tell me the formula product and formula name?   !{¤©¤}! is pulling your leg when he calls it a double replacement.  actually, no reaction takes place. nitrate has already combined with both metals (lead and silver). in solution, the ions will dissociate, but there will be no chemical reaction. everything is already chemically combined, and there are no imbalances that will lead to a reaction.
