Redox Reaction

4. Electrochemical cell in which a spontaneous chemical reaction causes a flow of electrons
8. A system in which there's an electric current flowing while a chemical reaction occurs.
12. Part of a voltaic cell that connects two containers and allows flow of ions.
13. An oxidation-reduction reaction.
14. A substance that tends to bring about reduction by being oxidized and losing electrons.
15. Number assigned to keep track of electron gain or loss in redox reactions.

1. A substance that tends to bring about oxidation by being reduced and gaining electrons.
2. Reaction that shows either the oxidation or reduction portion of a redox reaction.
3. Site at which oxidation or reduction; an anode or cathode.
5. The negatively charged electrode of an electrical device.
6. A process in which an electric current forces a nonspontaneous reaction to occur.
7. The loss of electron.
9. A cell that requires a nonspontaneous chemical reaction to occur (uses battery).
10. The positively charged electrode of an electrical device.
11. The gain of electron.
