Lead and silver nitrate will react to produce silver and lead nitrate. Pb(s) + AgNO3(aq) --> Ag(s) + Pb(NO3)2(aq) We can know this by referring to an activity (also called reactivity) series for metals, which lists metals in a vertical list such that any metal will replace any metal below it on the list. Lead is above silver, therefore, the lead will replace the silver in the silver nitrate compound. For an activity series from Wikipedia, refer to the related link below.
