Students will be given the formula for a cation or anion on a slip of paper or index card. He or she will find another student with an ion with the opposite charge and practice writing the formula and naming the ionic compound that would result by combining the cation and anion. Students also answer a few questions about naming and formulas of binary molecular compounds with their partner.
<p>This activity has students use Spartan to build an energy diagram for an SN2 reaction as a function of bond length. The activation energy can then be used to determine the rate constant for the reaction. After a few intoductory questions to orient general chemistry students to the organic reaction (with a short class discussion), the instructions lead them step-by-step to build the energy diagram for CH<sub>3</sub>Cl + Cl- --> Cl- + CH<sub>3</sub>Cl.
This 2011 video by the Chemical Safety Board is a very serious and moving motivation for adopting safe practices in the chemical laboratory. It focuses on two recent and very real safety issues in University labs (UCLA, 2008 and TTU, 2010 ), both of which have shaken the educational research community to result in positive change.
I have shared a "SafeShare" link so that you will not have to listen to ads, and if you choose to play the link in your classroom, you will not see all the Youtube ads on the screen.
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.

This five slides about came to be from a discussion that happened after Marta Guron and Jared Paul gave a talk at the Philly ACS in Fall 2016. This is a modified version of a presentation given to all chemistry students regarding the proper handling and disposal of chemicals. Certain details will need to be modified to fit your individual institutions. The particular focus of the slides is for students to learn to turn to SDS sheets before using chemicals and to be able to read the labels on chemicals and understand the associated safety concerns.
This is an HTML program that helps you spell with symbols of chemical elements for anything you want. Just cut and paste the text, paragraph or list of names you would like to "symbolize" in the left field. The program automatically displays the words that could be spelled with chemical symbols in the right field. When a word has more than one possible spelling, all of the possible combinations are displayed on a single line.
A rubric articulates the expectations for an assignment and enables faculty to assess student work in a rapid and consistent manner.
This Five-Slides About was developed for the TUES 2016 workshop Organometallica at University of Michigan. It was presented in conjunction with Chip Nataro's modeling of the development of a literature discussion learning object (Ligand effects in titration calorimetry from the Angelici lab).
This exercise introduces students to many chemical resources found on the internet. Rather than being geared for upper-division chemistry majors, much of the material introduced is appropriate for freshmen and sophomore level students (although more advanced students will also benefit from the exercise). The “web guide” contains links to many search engines and resources with brief descriptions of each while the “web report” has a number of exercises that asks students to search for chemical information. The assignment is self-guided; students are encouraged to choose topic of interest t
This is a question based approach for a discovery activity about cyclic voltammetry. The slider bar on a movie can used to control a variable and the displayed graph is updated to show the results. (You could also just play the movie to get an idea of what changes.)
The questions to be answered are
What is the shape of a cyclic voltammogram?
How are cyclic voltammograms affected by E0?
How are cyclic voltammograms affected by concentration?
How are redox equilibria affected by scan rate?
What if there are two reductions?
