Frequently Asked Questions
What does this quiz measure?
It measures knowledge of balancing chemical equations using conservation of atoms and correct coefficient ratios. Items include elements, compounds, combustion reactions, and reactions with polyatomic ions.
How many questions are included and how long does it take?
The quiz contains 16 questions. Estimated completion time is about 10 minutes.
What rules should be followed when selecting coefficients?
Use whole-number coefficients that balance the number of each atom on both sides. Use the smallest whole-number set unless an item states otherwise.
Are subscripts, charges, or formulas allowed to be changed?
No; only coefficients should be changed. Subscripts and chemical formulas must remain unchanged, including polyatomic ions when they appear as intact units.
How are scores reported?
The final score is placed into one of three knowledge bands. The bands indicate relative mastery of common balancing skills and errors.
