Cells

Question 1

How does a simple cell work?

Answer 1

.Set up similar to electrolysis
.Two electrodes must be able to conduct electricity
.Electrolyte must contain ions that conduct
.This sets up a potential difference so electricity can flow through the wire

Question 2

How does a rechargeable battery work?

Answer 2

Electricity reverses the reaction

Question 3

hydrogen-oxygen fuel cell anode half-equation

Answer 3

H2 –> 2H+ + 2e-

Question 4

hydrogen-oxygen fuel cell cathode half-equation

Answer 4

O2 + 4H+ + 4e- –> 2H2O
