Producing and Testing for Gases

If you knew that you were likely to develop Alzheimer's disease in your future, how would it affect your life in the meantime? This and other similar thought-provoking questions are discussed in a lesson plan about the availability of...

An outstanding lesson awaits your physics fledglings! After reading about how hydrogen can act as an energy carrier, they examine the electrolysis of water using solar power. They test the gases produced for flammability and will...

Here is a copy of a past national challenge exam that you can use in your general chemistry course as a unit or semester review. Sixty multiple-choice questions query learners on properties of matter, stoichiometry, reactions, and...

Recycled Russian nuclear weapons provide 10 percent of the nuclear energy that the United States uses. The short presentation discusses the Teller-Ulam device. It provides a diagram of the parts as well as a description of the four...

How can a chemist tell what gas a chemical reaction produced? Part two of a ten-part series prompts pupils to discover a number of simple tests that can reveal the identity of a gas. The video reinforces the concepts of solubility,...

If most gases are invisible, how do we know so much about them? Pupils practice associating the name, formula, testing method, and outcome for four common gases using an interactive. Users build on the content of their first puzzles to...

High schoolers conduct an experiment using the reaction of hydrogen and oxygen. After pairs balance the chemical equation for making water, they mix different ratios of hydrogen and oxygen in a chemical reaction. Classmates...

Scholars think color-change tests are the best! Show them how to differentiate between alkanes and alkenes using a short video. The narrator guides them through the test and the reactions that occur for alkenes. Other topics include...

Let the true colors shine through. Pupils conduct a flame test to identify an unknown element. Class members calculate and prepare specific molarity solutions of three chemicals. Using their observations of the colors emitted, they...

Students are introduced to the concept of hydrogen technologies through inquiry-based classroom activities.
