Stoichiometry with Beads

Teaching and learning the concept of limiting reactants can be challenging. In this activity students manipulate beads to learn about stoichiometry. A virtual drag & drop version is also available. 

Fun with Formula Stoichiometry: “Who poisoned Veronica Merriweather?”

"Who Poisoned Veronica Merriweather?" is a fun application of formula stoichiometry for students who are placed in the role of a CSI lab sleuth helping to interpret chemical data to identify a murderer. Topics covered include formula stoichiometry, percentage composition, empirical and molecular formulas and gas chromatography–mass spectrometry.

Solubility, Stoichiometry and Non-stoichiometry

The unspoken word of chemistry: Non-stoichiometric. Stoichiometry and non-stoichiometry are concepts that combine to make a solution that does not have to be difficult to understand.
