NOTES: ACIDS, BASES, SALTS

Mr.Hatfield's Chemistry students have completed their Notes on material from Chapter 19.   They can download a copy of the Power Point containing those Notes HERE:

Students received a Study Guide based upon this section of Notes in Friday's class, to help prepare for their Unit 7 test on Wednesday, April 3rd.

VIDEO: 'REDOX' REACTIONS

Tyler DeWitt has made a very handy, easy-to-understand video that uses the formation of an ionic compound (NaCl, sodium chloride) to illustrate the logic of oxidation-reduction reactions, sometimes called 'redox' reactions, as described in Chapter 20.

Tyler not only gives an example of oxidation numbers (20.2), but he also shows how to to use these numbers to describe 'half-reactions' (20.3)

While there is no worksheet based upon this video, this is highly-similar to how students will be introduced to these concepts in Lecture, and is worth repeated viewings:

VIDEO: ACID-BASE EQUILIBRIUM

Students were shown this video in Friday'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:

POWER POINT: 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 11th.  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 15 (THE IDES OF MARCH) 

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 were also finished.  Both items should be treated as homework, and completed as soon as possible.

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:
