This is a shorter version of a previously published Learning Object. This version focuses on bond enthalpy calculations and has students think about the risks and safety precautions for the synthesis of an explosive material (nitrogen triiodide).
There is also a longer version of this activity posted as a literature dicussion.
This LO is part of a special VIPEr collection honoring the 2021 ACS National Award recipients in the field of inorganic chemistry. Karl O. Christe was the recipient of the M. Frederick Hawthorne Award in Main Group Inorganic Chemistry for major and original contributions to main group chemistry.
The activity itself requires nothing more than a table of bond enthalpies and access to a laboratory handout and journal publication.
We discuss the simplest questions together after completion, noting the common pitfalls. I collect the students' work to see their individual perspectives on lab safety. They will see some content from the activity later on an exam.
This is a shorter version of a previously published Learning Object. I am also posting this as a separate Learning Object so that it can be categorized as an in-class activity instead of a literature discussion.
