Students were shown this video in today's class. 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:

SYLLABUS, UNIT 7
Students, here is the Syllabus for Unit 7, which focuses on acids, bases, salts, titrations and electochemistry. Please note that there are three sections of the textbook to review, and three labs in this Unit. On the day you receive this Syllabus in class, there will 45 days of instruction left in the semester:

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 will be made available in class on Monday, March 19th. If you need to get another copy, you can download a PDF version of the Study Guide HERE.
YOUR UNIT 6 TEST ON THERMOCHEMISTRY AND KINETICS is on Wednesday, March 21st. As always, extra time is available at LUNCH or AFTER-SCHOOL.

POWER POINT NOTES: THERMOCHEMISTRY
Students:
Here are the Power Point Notes for Unit 6: Thermochemistry.
In this you will find discussions of phase changes (again!), heat transfer, the 1st and 2nd Laws of Thermodynamics, and problems to calculate energy (q) , specific heats and enthalpies of reaction:

VIDEO: ENTHALPY OF REACTIONS
The following video by Paul Anderson was introduced in class on Thursday, Feb. 23rd. 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.
