<tt>Quiz 6: Chapter 20 and Ch 23 (23.1-23.2)
</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>Sections 20.1-20.5:
</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>Understand oxidation states (oxidation numbers), redox
reactions,
</tt><tt><br>
</tt><tt>what is oxidized and reduced and what are oxidizing and
reducing
</tt><tt><br>
</tt><tt>agents (oxidant and reductant).
</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>Be able to balance redox reactions using the half-rxn
method.
</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>Understand voltaic cells. Remember, oxidation occurs at
the
</tt><tt><br>
</tt><tt>anode and reduction at the cathode. Understand the
shorthand
</tt><tt><br>
</tt><tt>notation as given in lecture and the notes (and homework
</tt><tt><br>
</tt><tt>exercise 20.99 in 12th ed., 20.95 in the 11th ed. and 20.93
</tt><tt><br>
</tt><tt>in the 10th ed.).
</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>Understand cell potentials and standard cell potentials and
</tt><tt><br>
</tt><tt>how the two are related. Understand how to calculate them
</tt><tt><br>
</tt><tt>from reduction potentials. Understand how standard
reduction
</tt><tt><br>
</tt><tt>potentials relate to the strengths of oxidizing and
reducing
</tt><tt><br>
</tt><tt>agents. You need to know what is meant by standard
conditions
</tt><tt><br>
</tt><tt>(1 M for conc of things in soln and 1 atm partial pressures
</tt><tt><br>
</tt><tt>for gases).
</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>Understand how E and delta(G) are related and how E^o and
</tt><tt><br>
</tt><tt>delta(G^o) and the equilibrium constant are related and
that
</tt><tt><br>
</tt><tt>a negative delta(G^o) and positive E^o indicate a
spontaneous
</tt><tt><br>
</tt><tt>rxn and a K > 1.
</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>Section 20.6: Nernst Eqn. You should be able to use this
eqn.
</tt><tt><br>
</tt><tt>to calculate the E for a cell under nonstandard conditions.
</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>Sections 20.7 & 20.8: Batteries and fuel cells and
corrosion.<br>
Understand batteries in general, you don't need to memorize<br>
specific batteries. </tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>Section 20.9: Electrolysis, quantitative aspects of
electrolysis
</tt><tt><br>
</tt><tt>(stoichiometry). What are the differences between voltaic
and
</tt><tt><br>
</tt><tt>electrolytic cells.
</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>You should be able do to homework problems 20.1-20.119
</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>For those of you using the 12th edition the quiz covers
sections
</tt><tt><br>
</tt><tt>20.1-20.9 and homework problems 20.1-20.120
</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>For those of you using the 11th edition the quiz covers
sections
</tt><tt><br>
</tt><tt>20.1-20.9 and homework problems 20.1-20.121
</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>For those of you using the 10th edition the quiz covers
sections
</tt><tt><br>
</tt><tt>20.1-20.9 and homework problems 20.1-20.119
</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>Review section 4.4 (Redox Reactions). It would also be a
good idea to
</tt><tt><br>
</tt><tt>do homework problems 4.9, 4.45-4.52 (4.9, 4.45-4.52 in the
11th edition
</tt><tt><br>
</tt><tt>and 4.45-4.51 in 10th edition). Also, see the following
worksheet for
</tt><tt><br>
</tt><tt>additional practice on oxidation numbers.

24 (24.1)
</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>Transition metals, properties of transition metals,
lanthanide contraction,
</tt><tt><br>
</tt><tt>electron configurations and oxidation states (electrons
come out of the s
</tt><tt><br>
</tt><tt>orbitals first), magnetism (understand the different
types).

bonding (Lewis
</tt><tt><br>
</tt><tt>acid-base rxns), be able to determine oxidation number and
coord. number of
</tt><tt><br>
</tt><tt>the metal in a complex or coord. cmpd., geometries (often
depend on the
</tt><tt><br>
</tt><tt>ligand - ligands which carry substantial negative charge
reduce the the coord.
</tt><tt><br>
</tt><tt>number, i.e. # atoms directly bonded to metal atom)
