Graph and Matricies
Introduction One of the most interesting applications of linear algebra is to the problem on network analysis. The system of highways or city roads constitutes a network, as does a telephone communication network, or even the World Wide Web. In order to analyze highly complex networks, it is necessary to use fast computers and advanced methods, but the journey must begin somewhere and I hope that for you it starts here today, by analyzing some...

Experiment Write Up Proposal You will write up a synthesis procedure for one reaction that could be potentially run in a face- to-face Chem 2321 lab session. Your proposal will include an introduction and procedure. The procedure will include step-by-step instructions for running the reaction (including reaction monitoring), work-up. (product isolation and purification), and analysis (characterization). You will need to include sample calculations for percent yield and provide sample spectra analysis. You must upload your proposal as a single document...
