antagonistic muscle pair on arm

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. 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.

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.
