Two animated slides explain the decomposition reactions that occurs within a catalytic converter. An enthalpy diagram is displayed. Hess's Law is demonstrated. Finally, the analogy of football is used to explain Hess's Law. This clever...

Sixty multiple-choice chemistry questions make up this comprehensive exam used for the 2001 US National Chemistry Olympiad. Every topic that you would expect to approach in a general chemistry class is queried on. You could easily use...

A beautifully designed, eighteen-page chemistry tutorial awaits your learners. The main topics: enthalpy and entropy. By completing this lesson, students will be able to define these concepts, determine whether each is increasing or...

In this chemistry video, Sal takes a closer look at what happens to the change in enthalpy during a chemical reaction. He points out that the enthalpy change, given constant pressure, becomes the heat added to the system at that constant...

Sal introduces students to the term, "enthalpy" in this chemistry video. He defines enthalpy as: the internal energy, plus the pressure times the volume found in a system. He constructs a PV diagram to illustrate this point.

National Chemistry Olympiad tests are released after their use each year, since they cannot use them again for this event. The result: outstanding comprehensive assessment resources for general chemistry classes! This 2005 version covers...

No practice problems are given on this handout; it is a detailed list of concepts to know and tips for working related problems in chemistry. Give this to learners as a study guide, or use it early in your career as a chemistry...

In this thermodynamics worksheet, students calculate the change in enthalpy for several given chemical equations provided. Students specify if the reaction was endothermic or exothermic in nature.

In this chemistry worksheet students complete chemical equations by calculating what the ending formula will be and balance equations. 

In this chemistry interactive quiz, students answer 15 multiple choice questions on chemical bonding, enthalpy and Lewis structures.

In this enthalpy of reactions instructional activity, students use a known amount of copper (II) sulphate solution and an excess of zinc powder to calculate the enthalpy change of the reaction. Students measure the temperature change...
