calistry calculators

Submitted by Adam Johnson / Harvey Mudd College on Wed, 01/18/2017 - 18:17
Description

I just stumbled on this site while refreshing myself on the use of Slater's rules for calculating Zeff for electrons. There are a variety of calculators on there including some for visualizing lattice planes and diffraction, equilibrium, pH and pKa, equation balancing, Born-Landé, radioactive decay, wavelengths, electronegativities, Curie Law, solution preparation crystal field stabilization energy, and more.

I checked and it calculated Zeff correctly but I can't vouch for the accuracy of any of the other calculators. 

Basics of Lanthanide-Based Photophysics

Submitted by Jacob Lutter / University of Southern Indiana on Thu, 06/30/2016 - 14:27
Description

This 5 slides about outlines the basics of lanthanide photophysics as a primer for those new to the topic.  These properties are very unique and actually very useful, which is a topic for another time.  The intricacies of what causes the Ln luminescence, its strengths and drawbacks are discussed along with how these drawbacks are addressed in molecular complexes.  Notes for the instructor are included that explain each slide.

Online Homework for a Foundations of Inorganic Chemistry Course

Submitted by Sabrina Sobel / Hofstra University on Mon, 06/27/2016 - 18:08
Description

The Committee on Professional Training (CPT) has restructured accreditation of Chemistry-related degrees, removing the old model of one year each of General, Analytical, Organic, and Physical Chemistry plus other relevant advanced classes as designed by the individual department. The new model (2008) requires one semester each in the five Foundation areas: Analytical, Inorganic, Organic, Biochemistry and Physical Chemistry, leaving General Chemistry as an option, with the development of advanced classes up to the individual departments.

Inquiry-Based Introduction to Carbonyl Ligands

Submitted by Emily Sylvester / Duquesne University on Mon, 06/27/2016 - 17:20
Description

This in-class worksheet introduces students to the different ways we describe organometallic ligands – bonding, properties, spectroscopy, etc. – using carbon monoxide as an example. It is structured as an inquiry-based activity, where students work together in small groups but check in with the entire class at appropriate intervals. I plan to use this activity with my advanced inorganic students next year.

Will it Float? Density of a Bowling Ball Activity

Submitted by Terrie Salupo-Bryant / Manchester University on Mon, 06/27/2016 - 15:17
Description

This activity was adapted from the J. Chem. Ed. article, “Discrepant Event: The Great Bowling Ball Float-Off.” In this activity students use a bowling ball and some basic materials to predict whether the ball will sink or float in a tub of liquid. 

Chapter 1--Stanley Organometallics

Submitted by George Stanley / Louisiana State University on Fri, 06/10/2016 - 14:45
Description

chapter 1 of George Stanley's Organometallics course: Introduction, Orbitals, Electron counting

This chapter is an overview of the field, with an emphasis on electron counting

The powerpoint slides contain answers to some of the in-class exercises, so those are behind the "faculty only" wall. I shares these with students after the class, but not before.

everyone is more than welcome to edit the materials to suit their own uses, and I would appreciate being notified of any mistakes that are found.


soapmaking activity

Submitted by Adam Johnson / Harvey Mudd College on Sat, 05/14/2016 - 22:36
Description

This in-class activity is designed to follow the linked lecture/demonstration on soapmaking. The soaps cure enough to be handled in 48 hours if kept warm, and the students can feel the difference in the canola/coconut oil soaps.

The calcuations go through the major reactions, functional groups, and physical properties of soap molecules, and ends with the calculation of molecular weight for a mixture of substances. This could be related to a later polymer unit.

soapmaking lecture/demo

Submitted by Adam Johnson / Harvey Mudd College on Sat, 05/14/2016 - 22:26
Description

This is a short presentation that outlines the major chemical reactions of soapmaking. Included are instructions for making two soaps, one from canola oil, the other from coconut oil. These two soaps have very different hardnesses, which can be explained by examining the structures of the oils. If you have never made soap before, it isn't that difficult, but it does use concentrated NaOH so is very caustic before the reaction is done. The linked websited have good instructions for soapmaking as well.

Nanomaterials Chemistry

Submitted by Anne Bentley / Lewis & Clark College on Wed, 03/23/2016 - 15:49

This list includes a number of LOs to help in teaching nanomaterials subjects; however, it is not exhaustive.

ColourLex - a colorful website!

Submitted by Vanessa / Albion College on Tue, 03/15/2016 - 13:49
Description

ColourLex (colourlex.com) is an amazing website that mixes chemistry and art. The creators of this website have extensively catalogued paintings and the pigments that were used to create them. The pigments range from artificial to natural and organic to inorganic. You can search for the specific combination that you want to see.
