Quiz 2 will cover the following: Sections 11.4-11.6 and 13.1-13.2, 13.4
Sections 11.4-11.6:
There is some overlap with the quiz 1 material.
Phase changes, heating curves, critical T & P, vapor pressure,
boiling, melting, sublimation.
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,
be able to sketch one given this info, etc.).
You should be able do to any homework problems 11.4-11.7, 11.39-11.64,
11.73, 11.91-11.94
If you are using the 11th edition do homework problems 11.4-11.6, 11.33-11.56,
11.79, 11.87, 11.102-11.106
If you are using the 10th edition do homework problems 11.4-11.6, 11.33-11.56,
11.79, 11.87, 11.102-11.106
I've sumarized info about the four types of solids and their properties.
The types of solids are based on their attractive forces.
See the link "Types of Solids and Their Properties"
in the "notes" section of the course web page.

I also have another summary on line dealing with IAF, solids and solubility.
See the link "Ch. 11 & 13 - Review of IAF, Solids and Solubility"
in the "notes" section of the course web page (we haven't covered
the solubility stuff yet and you are not responsible for it yet).

Sections 13.1-13.2 and 13.4
Section 13.1:
Understand the solution process and energy diagrams, how solutions form,
ideal, endothermic and exothermic solution formation and the importance
of entropy in solution formation. In general, when things mix there is
an inc. in entropy (disorder) but this is not always the case. An inc.
in entropy is absolutely necessary for an ideal or endothermic solution
to form. This is not the case for an exothermic process. An exothermic
process already tends to be spont. so an inc. in entropy is not necessary
for this type of solution to form. There are cases in which the delta(H)soln
is negative, exothermic, and the entropy decreases (solution is more ordered)
and the solution forms. Also, understand the role of attractive forces
between particles in solution formation.
In the 12th edition the delta(H)_solvation is referred to as the
the delta(H)_mix.
Section 13.2:
Solubility, saturated, unsaturated and supersaturated solutions.
Section 13.4:
concentration units (know definitions, how to calculate them, how to use them
as conversion factors in problems and how to convert from one conc. unit to
another - see my examples in the notes and on the class web page on the easiest
way to approach these types of problems).
