Electron Transfer Reactions

Electron Transfer Reactions. Electron transfer reactions are oxidation-reduction or redox reactions. Results in the generation of an electric current (electricity) or be caused by imposing an electric current. Therefore, this field of chemistry is often called ELECTROCHEMISTRY.

Redox Reactions

Redox Reactions. Oxidation Number. The oxidation state of an element in an elemental state is zero. (O 2 , Fe, He) The oxidation state of an element in a monoatomic ion is the charge of that ion. (oxidation number of iron in Fe +3 is +3)

What did the chemist yell when she passed a cute guy in her sports car?

What did the chemist yell when she passed a cute guy in her sports car?. Radon, baby!. Balancing Redox Equations. Use the 5 step method! Number of electrons lost must be equal to the number of electrons gained You must balance your equation!. Ag 2 S (s) + Al (s) ? Al 2 S 3(s) + Ag (s).

Balancing REDOX Equations

Balancing REDOX Equations. Mr. Chapman Chemistry 30. Balancing Equations. In previous classes, we learned how to balance chemical equations by counting atoms. Following the Law of Conservation of Mass, we learned that the number of atoms on each side of the chemical equation must be equal.
