How to use activity series to predict products of single displacement reactions?

how to use activity series

Practice questions:

1.Cu(s) + 2AgNO3(aq) -->2Ag(s) + Cu(NO3)2(aq). Check if this reaction is posible according to the activity series.

Answer: the reaction is possible because copper is above silver in the activity series(Pure metal should be above above the metal in a compound in order for the reaction to take place).

2.Zn(s) + Pb(NO3)2(aq) -->Zn(NO3)2 + Pb

The reaction is possible because Zinc is above lead in activity series.

3.Pb + Zn(C2H3O2)2-->

This reaction is not possible because lead in not aboe zinc.

4Fe + Al2O3-->

This reaction is not possible because Iron is not above aluminum.
