VIDEO: BALANCING EQUATIONS

In this VIDEO, Mr. Hatfield provides equations for reactions involving both ionic compounds and covalent compounds.

Then, step by step, Mr. Hatfield balances all of these equations.  

Balancing equations is an iterative procedure, sometimes called 'trial and error', and students have to practice the skill of unpacking and balancing equations many times before it will become routine:

 

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 based on these Notes were made available in class on Thursday, March 18th, and were completed in class yesterday.  

Most students have already completed the Study Guide, handed it in and had the graded work returned to them in class so that they can use it to create their Notes for the next Unit Test, in their Composition Book.

If you need to get another copy, you can download a PDF version of the Study Guide HERE.

The previous Power Point Notes on Thermochemistry are available HERE.

VIDEO: EQUILIBRIUM

Students: as of today, we are in a new unit, on 'Solutions, Acids and Bases."  

The first topic in this new unit is chemical kinetics, where we examine things that affect the rate of chemical reactions, including the relative concentration of reactants and products. 

In this video, Paul Anderson does a great job of providing a demonstration that suggests how such 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 Thursday's class, including a short set of problems in which they will practice setting up equilibrium expressions.

This is a short topic, and on Friday the notes on Chemical Kinetics will be provided.  Both items should be treated as homework, and completed as soon as possible.

THERMOCHEMISTRY (ALL THE SLIDES!)

Students, you can download the Power Point Notes for Tuesday's Unit Test on Thermochemistry by either clicking HERE or on the graphic below:

Students should use this to complete their Study Guide, an Assignment which is due during Thursday's class, in order to prepare for Tuesday's UNIT TEST!

VIDEO: ENTHALPY OF REACTIONS

The following video was shared in class on Thursday, Feb. 17th.   

This video builds on material introduced by your instructor, Mr. Hatfield, during lecture on Wednesday, Feb. 16th.

In the video, Paul Anderson 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.  Copies of this Assignment were made available in class to complete in class that day.

VIDEO: TEMPERATURE

Students:  Here is the 'Temperature' video by Paul Anderson, as shown in class.  Make sure you use colored pencils to complete the graph on pg. 3 of the handout based on the video.

POWER POINT: THERMOCHEMISTRY (1st 15 SLIDES)

Students:

Here are the first 15 Power Point slides from Mr. Hatfield's Thermochemistry Notes.   Use these to 'catch up' on completing the first two pages of the Study Guide on Thermochemistry.  Click HERE or on the image to download these slides.
