<tt>Quiz 7: <b>Ch 17 (17.6-17.7), Chapter 5 (review) and Ch 19
(19.1-19.7)</b><b><br>
</b><br>
<b>Sections 17.6-17.7:</b><b><br>
</b><br>
Precipitation and separation of ions. Section 17.7 is just for<br>
your information about separation of ions. There will be no<br>
specific questions from 17.7. However, reading through this<br>
section may help you understand precipitation reactions and<br>
what types of compounds are usually insoluble and to what degree.<br>
There are a couple of homework problems to aid in this.<br>
<br>
Also, there is a Sample Integrative Exercise in this section you<br>
should be able to do.<br>
</tt><br>
<tt><tt>On the quiz, if you need to use an ICE table, you must show
the work<br>
and the ICE table. When making any assumptions you should show
that<br>
your assumptions are okay (less than 5% error). If the percent
error<br>
is greater than 5%, you need to solve the resulting quadratic
equation<br>
or use the method of successive approximations (both shown in
class<br>
and in the notes). You must show this work. If you don't, you
will<br>
not get full credit.<br>

<b>For the on-line homework:</b><b><br>
</b><br>
Do Ch 17 problems 16-20<br>
<br>
<br>
Chapter 5:<br>
<br>
Understand first law of thermodynamics (conservation of energy and<br>
E=q+w from ch 5), state functions, Hess's Law, Enthalpy of<br>
Formation and how to use these to obtain enthalpies of reaction.<br>
<br>
See my chapter 19 notes (pages 1-17 to get an idea of what sorts
of<br>
things you need to review from chapter 5).<br>
<br>
<br>
Sections 19.1-19.4:<br>
<br>
The 2nd and 3rd laws which deal with entropy. Understand the
diff.<br>
between reversible and irreversible processes. Should be able to<br>
calc. entropy changes for both system and surroundings for
reversible<br>
(equilibrium) and irreversible processes. Understand the
molecular<br>
interpretation of entropy and microstates as well as Boltzmann's
eqn<br>
(eqn 19.5). Be able to make qualitative predictions about changes<br>
in entropy. Be able to calc. entropy changes using standard<br>
entropies (eqn 19.8).<br>
<br>
Sections 19.5-19.7:<br>
<br>
Understand free energy and how it relates to enthalpy, entropy,
temp.<br>
and spontaneity. Know how to use std. free energies of formation
to<br>
calc. std. free energy changes for a rxn (eqn 19.14). Also,
understand<br>
how free energy under nonstandard conditions relates to standard
free energy<br>
and reaction quotient (19.19 in 12th ed., 19.16 in the 11th ed.
and<br>
19.21 in the 10th ed.). Understand the relationship between std.<br>
free energy and the equilibrium constant (section 19.7).<br>
<br>
Understand what the free energy change under nonstandard
conditions (deltaG)<br>
means and what the free energy change under standard conditions
(deltaG^o)<br>
means (i.e. deltaG tells you whether a rxn is spont or nonspont
under any<br>
conditions and related to the slope of the free-energy curve under
any<br>
conditions and deltaG^o tells you about the diff. in free energy
between<br>
the products and reactants and tells you where the position of the
minimum<br>
in the free-energy curve is, where the position of equilibrium
lies) - see<br>
section 19.5 and the last few pages in the notes.<br>
