Students should have been given the worksheet based on this video prior to Spring Break. In the video, Paul Andersen demonstrates the centrality of water to most acid-base chemistry, and explains how to calculate equilibrium constants for acids (Ka) and bases (Kb), and how to express those as pKa's or pKb's:

POWER POINT NOTES: ACIDS, BASES AND SALTS
Mr.Hatfield's Chemistry students should have completed their Notes on material related to pg. 146-171 (volume 2) of their textbook. They can download a copy of the Power Point containing those Notes HERE:
Students received a Study Guide based upon this section of Notes on March 22. This Study Guide will be completed before Spring Break. After Spring Break, Mr. Hatfield's classes will complete their titration labs and have a Unit Test on equilibrium, solutions, acids, bases and salts.

POWER POINT NOTES: CHEMICAL KINETICS
Students, here are the Power Point Notes on Chemical Kinetics, which covers the concept of equilibrium and the rates of reaction.
The Study Guide has been made available in class since Friday, March 17th. If you need to get another copy, you can download a PDF version of the Study Guide HERE.
UNIT 6 is now over, and all Unit 6 work is PAST DUE, and will NOT be accepted after Friday, March 24th
VIDEO: EQUILIBRIUM
In this video, Paul Anderson does a great job of providing a demonstration that suggests how chemical systems reach equilibrium.
Mr. Anderson also models how to equilibrium setups and solve for the value of the equilibrium constant, 'K'. Students were given a worksheet based on this video in Friday's class, along with a set of problems in which they will practice setting up equilibrium expressions.
This is a short topic, and the notes on Chemical Kinetics should be finished within the same day as viewing the video. Both items should be treated as homework, and completed as soon as possible.

POWER POINT NOTES: THERMOCHEMISTRY
Students, you can download the Power Point Notes for next weeks's Unit Test on Thermochemistry by either clicking HERE or on the graphic below:
Students should use this to complete their Study Guide, which is due this week, in order to prepare for next week's UNIT TEST!

VIDEO: ENTHALPY OF REACTION
The following video by Paul Anderson was introduced in class on Thursday, May 2nd. It helpfully reviews some of the information already given in lecture regarding heat and the enthalpy of reactions. It also features a very handy, step-by-step demonstration of how to apply Hess's Law (a SUBTLE and advanced topic) to calculate enthalpies.
Students have an assignment based on that video, which is available HERE as a PDF file.
