Abstract. Three new experiments
using cost-effective household products are used to explain the concepts
of Avogadro’s law, stoichiometry, and thermodynamic properties in introductory
and university level chemistry courses. These experiments are designed
to grab the students’ attention by presenting some surprising effects.
The methods of producing carbon dioxide and the effect of crushing containers
are very different from those in the literature. These demonstrations
have two advantages. First, carbon dioxide is generated in the original
containers, and second, the element of surprise stimulates the students’
interest to learn more about chemistry.
