General chemistry class members engage in a mini-unit on mole conversions. Through nine lab activites with varying degrees of difficulty, they practice measuring mass and volume, molar calculations, and stoichiometry. Terrific...

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...

Challenge young scientists to design their own experimental procedures. They write the procedure for properly preparing two grams of a water-insoluble ionic salt. To finish, they perform the experiment and collect data to prove their...

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

Radioactive decay, pH, properties of elements, organic compounds, and stoichiometry are all touched upon through this practice chemistry exam. It always helps learners to take a practice test in preparation for the actual exam. This...

Young scholars research chemical formulas and balance chemical equations.  In this chemical equations lesson students complete a class activity on chemical equations and answer questions.

In this chemistry overview worksheet, students review stoichiometry, states of matter, thermochemistry, gas laws, chemical bonding, molarity, chemical equilibria, and kinetics. This worksheet has 41 problems to solve.

Students investigate how to build and launch a simple rocket that uses hydrogen and oxygen gases that will be mixed to propel the rocket. Students learn the principles of combustion reactions, kinetics, stoichiometry of reactions,...
