These questions focus on balancing redox equations. You may wish to review oxidation & reduction or balancing equations you take the quiz.
The following questions are "fill in the blank", where you enter the coefficients in order to balance the chemical equation. In cases where only one molecule/formula unit is required, you must enter "1" into the box - do not leave it blank. These questions are for self-testing only, and are not suitable for assignments or exams.
