I taught chemistry for 25 years. I now provide tuition online. I just like nicely produced, imaginative resources. (NB &1.00 is the lowest price that I can charge for my resources, that have an unlimited license. For each £1.00 sale I receive £0.35)

I made a little cartoon to illustrate biceps and triceps contracting and relaxing to move the arm. Simply double click on the .html file, and it should open in your browser. Now has radius and ulnar. A preview is available at https://www.doctorexe.com/armmovement.html Please note: in order to provide a rich interactive experience, my interactive resources are mini-web sites local to your computer. After unzipping, they comprise a folder containing the main .html file and another folder containing the graphic resources and my coding to make the resource work. Double click on the .html file and the resource will work. If, however , you move or delete any of the files from this hierarchy, the resource will not work.

I needed a clean, scalable (vector)graphic of fleming’s left hand rule that I could freely use in my resources, so resorted to drawing my own. I thought I would share it. If anyone would like to use the editable SVG version or postscript or EPS etc, contact me.

Quick and short presentation on how to balance the manganate (vii) half equation, to save you time. I have now added the oxidation of ethanol by acidified potassium dichromate (VI) as another example.
