4. which metals will be able to reduce copper ions in solution?
5. will copper or lead be able to replace zinc ions in solution? why?
6. which metal will not be able to be oxidized by any of the other metals listed?

4. hydrogen, lead, tin, nickel, iron, zinc, aluminum, magnesium, sodium, calcium, potassium, silver, gold, copper, and lithium

5. iron because copper is more easily oxidized and therefore can rust faster. also iron is higher than copper on the activity series table.

6. gold

7. zinc would oxidize faster and this would be desirable because it forms a protective layer much like aluminum and this prevents furthur corrosion for alonger period of time.

8. copper might go into water you drink to clean you would be unable to drink the water.

9. reactivity increases the furthur down you go in the periodic table

10. the reactivity in group 17 (halogens) decreases as you go down the column of the elements in the group.
