Quiz 8: Ch 10 (10.9), Ch 11 (11.1-11.6), Solids (see below) :
Section 10.9:
Real gases (van der Waals eqn)
Homework coverage (you should be able to do all problems in the given ranges):
For those of you using the 14th edition do homework problems
10.12, 10.89-10.96, 10.113-10.117
For those of you using the 13th edition do homework problems
10.12, 10.91-10.98, 10.114-10.118
Sections 11.1-11.6:
Attractive Forces (AF) and their realtionship to properties of substances
and phase changes. Be able to look at various molecules and identify the
AF between them. Know how the AF in a molecule effect the properties (bp,
mp, sublimation pt., H_v, H_fus, H_sub, viscosity, surface tension, critical
temp.), phase changes.
Phase changes, heating curves, critical T & P. relationship between
vapor pressure and temp. (Clausius-Clapeyron eqn).
Remember: Stronger AF => lower vapor pressure and slower evaporation
generally, higher everything else:
(b.p., m.p., s.p. Hv, Hfus, Hsub,
critical temp., viscosity, surface tension)
The Clausius-Clapeyron Eqn is found in "A Closer Look" (section 11.5)
It was also discussed in class, exp 14 and in end-of-chapter exercises.
You should understand and be able to use the Clausius-Clapeyron Eqn.
(which you will NOT be given). This includes understanding the graph I
showed in lecture and you do for Exp 14. Homework problems dealing with
this are in the Additional Exercises section at the end of the chapter.
Phase diagrams (identify regions, vapor pressure curves
for solid and liquid and m.p. curve, various points on
these curves - like m.p., b.p. triple point, critical
point, why the m.p. curve leans right or left, etc.).
Homework coverage (you should be able to do all problems in the given ranges):
If you are using the 14th edition do homework problems 11.1-11.7,
11.9-11.64, 11.73-11.81, 11.83-11.87, 11.90-11.96
If you are using the 13th edition do homework problems 11.1-11.7,
11.9-11.64, 11.73-11.81, 11.83-11.87, 11.90-11.97
Sections on solids; 11.7-11.8, 11th ed. (on Carmen):
Sections 11.7 and 11.8 (10th & 11th eds.) For the 12th - 14th editions
use the ch. 11 material for these sections in the "Lecture" module in
Carmen. It's the submodule "Chapter 12: Solids - Structure and Bonding".
See my "Notes" link, "Chapter 11/12 - Solids".
Understand the unit cells (fcc, bcc, sc), and unit
cell calculations, packing in solids (hcp, ccp/fcc, bcc, sc),
bonding in solids. You will not be given the information we covered
in class (# particles per u.c., coordination #, % empty space, eqns
relating edge length to radius). You may even have to derive some
of these things (such as edge length and radius relationship,
# particles per u.c, etc.)
For ionic substances understand the unit cells and related information
given in class, notes and the textbook for NaCl.
This includes their structures, placement of the ions,
how anions and cations touch (along an edge, body-center, etc.),
relationship between edge length and radii of the ions,
number of nearest neighbors and what they are, for both the cation
and anion, type of "hole" each ion "sits" in, unit cell calculations,
etc. In doing unit cell calc. for ionic structures you must know how
many formula units there are in a unit cell (e.g. NaCl, ZnS and CaF2
all have 4 f.u. per unit cell, CsCl has 1 fu/uc). For CsCl, ZnS
and CaF2 you only need to know the # fu/uc. I've sent out a table
with all the information for these 4 ionic structures. You should
know what's listed for NaCl. For the other 3 ionic crystal structures
just know the #fu/uc.
For unit cell calculations you should be able determine the
following: density, volume (edge length and particle radius),
AW (MW, FW), unit cell type (sc, bcc, fcc) and Avogadro's Number.
This includes ionic structures.
The Chem dept has a website about crystal structures,
Visualizing Crystal Structures - OSU Chem Dept .
Click on "Crystal Structures".
It allows you to look at the unit cells, rotate them around, see
several unit cells together, etc. You can also find it at the "Notes"
link on the class web page, as well as couple of other web sites that
may prove to be useful. Make sure to click on "All Atoms". Also,
it can be helpful to ask for more than 1 unit cell. Don't ask for
more than 8 uc at a time, it gets too "busy".
Understand the 4 general types of solids and their properties.
I've sumarized this info in the table on the last page of the
notes for chapter 11/12 (depending on the textbook edition).
If you are using the 12th-14th editions do the homework
for these sections from chapter 11, 11th edition. The problems
are on Carmen.
Summary about the types of solids and their properties,
"Types of Solids and Their Properties"
There is another summary on line dealing with IAF, solids
and solubility.
See the link
"Ch. 11, 12 & 13 - Review or IAF, Solids and Solubility"
in the "notes" section of the course web page.
