Balancing Redox Equations

This page is an exercise in balancing oxidation-reduction equations. When you press "New Problem," a reaction will appear in a small window. In front of each chemical species will be an empty cell. Put the proper coefficient in each cell and then press "Check Answer", if the coefficient is 1, you may leave the cell blank. If you get a question wrong, the correct coefficients will be shown.  The results appear in the table below. Hints: Use only the smallest set of integer coefficients. Use TAB or the mouse to move between cells. If your answer is wrong, the correct coefficients will be shown when you click "Check Answer". Unlike most of the problem sets, the popup window with the question in this problem set does not disappear when you click the 'Check Answer' button. However when you click the 'Check Answer' button, the word correct or incorrect will appear in the Results box below, at this point you can click the 'New Problem' button below and a new question will appear.
