collision theory
When is a fatal car accident 'successful'? When used to explain reaction rates and collision theory. This may be a bit ghoulish, but comparing car collisions to particle collisions seems to work.

How do you write and balance redox equations? An earlier podcast explained how to write and balance half equations. This podcasts shows how to combine two half equations and arrive at a balanced overall redox equation.
Redox equation balancing need not fill you with fear. Blindly following these rules and you will be able to write a balanced half equation.
Its exam time. I've just finished marking some chemistry exams, and thought that it might be a good time to post some strategies to use to answer typical questions. ie How can you write an equation for, and determine what you would observe, in a chemical reaction?
High school chemistry calculations are often dressed up to appear to be more difficult than they really are. They just about always follow the same format. However I've just finished marking some chemistry exams and felt compelled to post this podcast. It describes the method that you should employ to solve high school chemistry calculations. (If you tried the sample calculation you should have got the answers (a)3.42A and (b) 5.50kg.)
I've been busy lately, and haven't had time to generate anything new myself. I forget where I got this video from, but it is a beauty. Makes you remember why you first got interested in chemistry ......... explosions! (This file is 15Mb so you will have to wait for a bit .... but it will be worth it!)
The first in a series of casts explaining the method used to name simple hydrocarbons.
Some of my class were singing 'Gimme Gimme a Redox Titration' today - it inspired me to post this acid/base version (to Bohemian Rhapsody).
Its been a while since I last posted .... been very busy. Have just tried new software for this post; a very brief introduction to hydrocarbons and organic chemistry. Hopefully more will follow.
You asked for it!! Here is the 'Gimme Gimme' redox titration karaoke. Let me know if you like these type of files..... I've got plenty of them!!!!!!!
Follow these simple rules and you will always be able to determine the oxidation state of an element.
A very brief recap of year 11 redox terminology and definitions. (vodcast)
The other day in class Elle was using her lip gloss. Here is a video of what we saw. What is going on? (vodcast)
Some introductory notes about naming covalent compounds. (Audio is from The Grates 'Science is Golden' -'Gravity Won't Get You High') (vodcast)
Equilibrium is a dynamic process, much like a game of footy. (audio)
OK so now you've performed a titration how can you make use of the data that you have collected? (audio)
How do we select an appropriate indicator for use in a variety of acid/base titrations? (audio)
How do we select a chemical for use as a primary standard? And what is a primary standard anyway? (audio)
This audio discusses the cause of polar bonds and polar molecules. (audio)
The second of two short podcsts on covalent bonding. This one looks at the intermolecular forces in covalent solids, ie Van der Waal forces. (audio)
A brief description of the factors that control the rate of a chemical reaction. (audio)
The first of two brief descriptionsof covalent bonding. This podcast looks at primary covalent bonds. (audio)
A brief description of metallic bonding. (audio)
This presentation compares collision theory to a foot y game. (vodcast)
A video file describing equipment used in titration experiments. (vodcast)
A brief description of ionic bonding. (audio)
