This is part two of the Entropy Worksheet worked on in class.

Short video shows how one calculates energy of combustion from bomb calorimeter data, then approximates enthalpy of combustion from the same data.

This short video describes and bomb calorimeter and an example of using the data from a bomb calorimeter experiment to calculate the change in internal energy for a chemical change.

This video describes how one can write a thermochemical equation based on constant pressure calorimetry data.

Intensive and Extensive properties presented by Dr. Paul McCord.

State Functions presented by Dr. Paul McCord.

This video covers Questions 1 - 4 on Entropy Worksheet.

Vapor pressure, evaporation and equilibrium presented by Dr. Paul McCord.

Intermolecular forces presented by Dr. Paul McCord

This short video explains that it is possible to combine bonding theories to most accurately understand and predict observable physical and chemical properties of molecules.

This short video is the last in a series of 8 videos explaining Valence Bond Theory. This video describes the hybridization that must occur to explain the electronic geometry found in compounds that form with expanded valence.

This short video is seventh in a series of 8 videos describing the basic ideas of Valence Bond.

This short video is 6th in a series of 8 videos explaining the VB hybridization.

This short video is fifth in a series of 8 videos describing the VB theory.

This short video is the 4th video in a series of 8 videos describing basic VB theory. The video uses water as an example of a tetrahedral electronic geometry yielding sp3 hybridization.

This short video is the third video in a series of eight videos explaining the VB theory. Here is a short explanation of the sp3 hybridization which occurs in the compound, ammonia.

This is the second video in a series of 8 videos building the concept of VB theory. This video looks at the sp3 hybridization in methane.

This video is an introduction to Valence Bond Theory. It is first in a series of 8 videos on this subject.

Line Drawing for Organic Molecules

This short video reviews the names of the electronic and molecular geometries associated with expanded valence compounds.

This short video works out three examples of predicting molecular shape based on the Lewis structure of the molecule.

This short video is an introduction for VSEPR

VSEPR Theory presented by Dr. Paul McCord

This short video gives three elements that can form stable compounds with incomplete octets. These are exceptions to the octet rule, and the particular elements are H, Be and B.

This short video describes the situation in which the octet rule is broken when a stable structure is formed with an expanded octet. This is demonstrated via worked examples describing the Lewis structures of PCl5 and XeF4.

Lewis structure of sulfur trioxide showing the concept of resonance due to the multiple allowed positions for the double bond within the molecule.
