In this chemistry olympiad lab worksheet, chemists are required to design two experiments. In one, they design an experiment to identify seven solutions given to them in pipettes. In the other, they design an experiment to determine the...

The National Chemistry Olympiad exams are comprehensive tests covering an entire  year of chemistry concepts. You can use them as practice for competing in the challenge, or simply as a review, or as an actual final exam for your...

Sixty multiple-choice questions test on a variety of first year chemistry subjects. In order to succeed, exam takers must be competent with properties of elements, stoichiometry problems, gas laws, bond dissociation, and types of...

As to be expected from the American Chemical Society Olympiad Examinations Task Force, this 60-question test tops the charts in terms of excellence. It consists entirely of multiple choice questions designed to assess a year's worth of...

In this chemistry worksheet, test takers answer 60 multiple choice questions on topics related to chemistry from balancing equations to calculating moles and molecules of compounds. They name formulas, they convert, they solve problems...

A very simple example of a functional relationship between depth of water and time is shown here. In fact, it might be more useful to use a coastal tide book to better illustrate this real-world experience. Pupils are to count the number...

In this chemistry olympiad problem solving worksheet, chemistry pupils solve eight problems on a variety of topics including periodic trends, phase changes, ionization reactions, catalysts and titrations.

A variety of topics including reaction rates, combustion reactions, periodic trends, and ionization reactions are included in this exam. Test takers also practice calculating empirical and molecular formulas of compounds.

Only eight problems are on this competitive national chemistry exam. It required the balancing of chemical equations, solving stoichiometry questions, and more. This is part two of three of the national exam. Also available is a...
