Information
for Halverson’s chemistry students.
The chapter numbers relate to our textbook, World of
Chemistry by Zumdahl (McDougal Littell pub.) 2007
edition.
Chapter 3: Chemical Foundations: Elements, Atoms,
and Ions
Here is an interactive Periodic Table with useful data on
every element. It can help with the homework!

A table of Specific Heat Capacities is here: (You will need
it for the heat capacity lab)

University of Strasbourg's software to simulate looking at
atomic spectra through a real spectroscope:

To simulate the spectroscopes we use in class, use these
settings: Linewidth=10, continuum=0.2, contrast=2
The periodic table, electron orbitals, in an interactive
format. Also a good downloadable periodic table:

Chapter 17: Equilibrium
Video of Halverson demonstrating Le Chatelier's principle.
Explanation: 0.2M CoCl2 solution (pink) is made
to turn blue by adding HCl.
The reaction is: Co2+ + 4Cl-
<-----> CoCl4 2-
Addition of Cl- ions, in the form of
concentrated HCl, forces the reaction to the right, as
predicted by Le Chatelier. The CoCl4
2- is blue.
Later, dilution by water allows the reverse to happen,
returning the solution to its original pink color.
Finally, the waste acid is neutralized by dumping it into a
sodium bicarbonate solution, converting it to salt water
and carbon dioxide.
HCL + NaHCO3 ----> NaCl + H2O +
CO2
General purpose chemistry video
Here is a video series that I like to show in my chemistry
class: The World of Chemistry, with
experiments by Don Showalter, and introductions by
Nobel prize-winning chemist Roald
Hoffmann.
