What are the two main components of a voltaic cell
Electrode
Electrolyte

14. Difference between a dry and wet cell
Category 3: $200
Difference between a dry and wet cell
Liquid vs. paste

15. Explain the function of an electrolyte in a cell
Category 3: $300
Explain the function of an electrolyte in a cell
Allows ions to flow between electrodes, interacts with electrodes releasing electrons and ions.

16. Category 3: $400
When does a battery die?
When no more chemical reactions can take place (the electrode is used up)

17. Category 3: $500
Describe how a solar cell works and why it is better for the environment
