All Science is Either Inorganic Chemistry or Stamp Collecting (Rabinovich)

Submitted by Shirley Lin / United States Naval Academy on Thu, 04/01/2021 - 10:19
Description

This LO consists of some web resources for discussing chemophilately, the study of chemistry through postage stamps.

This LO is part of a special VIPEr collection honoring the 2021 ACS National Award recipients in the field of inorganic chemistry. Daniel Rabinovich was the recipient of the ACS Award for Research at an Undergraduate Institution for a career involving outstanding supervision and mentorship of undergraduate chemical professionals in synthetic inorganic chemistry

 

The Organometallic Chemistry Behind the Polymer of Squares (Chirik)

Submitted by Megan Mohadjer Beromi / Princeton University on Sat, 02/20/2021 - 12:34
Description

The discussion covers a 2021 publication by the Chirik group (Nature Chemistry, 2021, DOI: 10.1038/s41557-020-00614-w) which details the discovery of a new way to polymerize butadiene through iron-catalyzed [2+2] cycloadd

Buffer solutions Virtual Lab

Submitted by Mona Kulp / Smith College on Wed, 01/27/2021 - 15:34
Description

This is a virtual adaptation of a buffer capacity lab experiment using the chemcollective digital workspace.  Students learn to make buffers in different ways and then test the capacity of their buffers to understand what makes an optimal buffer.

Description

In this online Electrochemistry Experiment, students use an Electrochemical Cell Simulator to construct electrochemical cells, measure voltages, and interpret results.

 

Cisplatin and Anticancer Therapy: The Role of Chemical Equilibrium

Submitted by Jack Eichler / University of California, Riverside on Thu, 02/20/2020 - 16:18
Description

This is a flipped classroom module that covers the concept of dynamic equilibrium, and how dynamic equlibrium plays a role in the anticancer mechanism of the therapeutic cisplatin.This activity is designed to be done at the end of the typical second quarter/second semester general chemistry equilibrium unit. Students will be expected to have learned the following concepts prior to completing this activity:

Time-Integrated Rate Laws and the Stability of Gold(III) Anticancer Compounds

Submitted by Jack Eichler / University of California, Riverside on Thu, 01/16/2020 - 14:55
Description

This is a flipped classroom module that covers the concepts of time-integrated rate laws. This activity is designed to be done at the end of the typical second quarter/second semester general chemistry kinetics unit. Students will be expected to have learned the following concepts prior to completing this activity:

Reaction Mechanisms: Energy Profiles and Catalysts

Submitted by Wes Farrell / United States Naval Academy on Thu, 01/02/2020 - 13:44
Description

This in class activity consists of two demonstrations to be performed by the instructor, followed by a worksheet that students may work on independently or in groups.  The demonstrations allow the students to determine when a reaction has occured, when it has not occured, and generate qualitative reaction energy profiles to match these observations.  This activity is designed to take place during a description of kinetics in general chemistry. Detailed descriptions of the procedure and activity may be found in the "Overview for Instructor."

Thinking about Electron Configurations and Magnetism

Submitted by Jack Eichler / University of California, Riverside on Fri, 12/13/2019 - 15:30
Description

This activity is designed to be done in the middle of the typical first quarter/first semester general chemistry electronic structure unit. Students will be expected to have learned the following concepts prior to completing this activity:

a) how the four quantum numbers are determined (principal quantum number, angular momentum quantum number, magnetic quantum number, and electron spin quantum number);

b) the basic concept of electron spin, and how atomic orbitals that possess two electrons will result in the spin-paring of electrons;
