Please predict what will happen.
Im not very good in chem.
Iron metal and pb(NO3)
Lead metal and Mg(9NO3)2
Copper metal and AL(NO3)3
Lead metal and AgNO3
On the first, iron is more active than lead, so the iron displaces the lead.
On the last, lead is more active than silver, so silver will be displaced.
On the other two, nothing.
