Unit 0: Prior Knowledge/ Summer Study

The following topics are expected as general, pre-requisite knowledge for this class. Students should be familiar with the chemical topics covered on this page. It is possible that a refresher and some light practice may be necessary for some topics. These topics include: introduction to matter, significant figures, measuring devices, dimensional analysis, density, volume, and stoichiometry, nomenclature, and balancing chemical equations.
