The Advanced Stoichiometry STEM Certificate is a self-guided program that reinforces the topics of stoichiometry with students, including: dimensional analysis, conversion factors, chemical formulas, ...

Magnesium metal is dissolved in HCl in 500mL Florence flasks covered with balloons. The moles of each reagent are changed in each flask in order to demonstrate the limiting reagent concept. In flasks ...

The concept of the mole to use determine relative amounts of reactants is explored. Mole/Mole and Mole/Mass Stoichiometry Problems: The concept of the mole to use determine relative amounts of ...

Students learn how to calculate the percent yield for a chemical reaction. Mass/Mass Stoichiometry: Problems and Percent Yield: Students learn how to calculate the percent yield for a chemical ...

Human activities have differentially altered biogeochemical cycling at local, regional and global scales. We propose that a stoichiometric approach, examining the fluxes of multiple elements and the ...

This module connects ideas across topics in a first semester introductory chemistry course to explore the impacts of combustion reactions. By motivating students to understand the relationship between ...

Ammonia cracking, decomposing ammonia into its constituent nitrogen and hydrogen molecules, is gaining traction as an emerging source for cleaner hydrogen. However, this reaction is very endothermic ...
