1
Q
identify RELATIONSHIP between DISPLACEMENT and ACTIVITY of metals
A
- active metal displaces less active metal ion from solution
- more active metals make smallest E0 and better resultant
- if metal atom active, metal ion less active
2

A
generate electricity from redox reaction where chemical energy is converted in electrical energy
3
Q
