Stoichiometry

In this stoichiometry worksheet, students solve thirty problems using the process of stoichiometry to find moles, molecules, and masses of substances in chemical reactions. Students balance chemical equations, find limiting reagents and...

In this density worksheet, learners are given 11 problems and they determine the density of the substance, the mass of the substance or the volume. They write the equation they use to solve the problem, they show their work and they box...

I would weigh less on the moon? Send me there, then! On the top of the first page, a cartoon image demonstrates the difference between Earth and the moon. It then goes on to describe weight and mass and provides five practice problems...

This is the grown-up version of the classic "float an egg in salt water" experience, plus an experiment in soap making. High schoolers explore density, but more importantly, practice accuracy, precision, and the use of significant...

Change the density of water by adding minerals. The presentation discusses density—from the definition to calculations—and applies it to the real world. It briefly mentions specific gravity, and finishes by showing Archimedes'...

After giving the definitions of the different compound terms and formulas, equations are provided to teach your chemists to calculate different values. Relative formula mass, atomic mass, and empirical mass are shown and explained with...

Real world chemical reactions are used as examples for teaching stoichiometry. Viewers work through air bag inflation, fat conversion to water in a camel, rocket fuel combustion, and carbon dioxide removal in spacecraft. Make...

The term stoichiometry derives from the Greek words stoicheion meaning element and metron meaning measure. The second Socratica video in a two-part series within a larger chemistry playlist introduces more complex stoichiometry...

A short video introduces the triangle that illustrates how to find any value given the other two in the density formula. Class members use the triangle to work several problems to find the mass, volume, or density of an object.

Students complete experiments discovering the relationship between density and mass. They use the internet to gather information before the experiment. They discuss the activity once it is completed.
