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 equilibrium worksheet, students solve eight problems including determining the effects of changes to a system as it related to Le Chatelier Principle, calculating equilibrium constants and finding boiling points of solutions.

In this gas laws worksheet, students calculate volume, pressure, or mass for given gas reactions. Students calculate partial pressures for given gases. This worksheet has 17 problems to solve.

Avogadro's law is stated in equation form. The lesson does not include much discussion, but it does relate the partial pressure and the total pressure of a gas sample to the mole fraction of its components.
