Only eight problems are on this competitive national chemistry exam. It required the balancing of chemical equations, solving stoichiometry questions, and more. This is part two of three of the national exam. Also available is a...

While this resource does not provide problems for chemistry learners to solve, it outlines skills that they should have and concepts that they should grasp. Topics include thermodynamics, periodicity, redox equilibria, transition metals,...

In this thermodynamics worksheet, students fill in the blanks with terms related to specific heat, calorimetry, phase changes, enthalpy, entropy and free energy.

Students listen to a lecture on the collision theory. They discuss the reactant and product changes during a chemical reaction. Students are taught the factors affecting reaction rates. They complete a lab on entropy, heat and free...

Through critical thinking, students realize that spontaneous events happen in a certain order. This lesson presents an examination of the Second Law of Thermodynamics using a thought story, rubber band inquiry, discrepant event and lecture.
