An updated and revised version of the original text, this handbook reviews the basic principles of physical chemistry, linear algebra and statistics, which are necessary to determine material and energy balances. Chapters topics include: dimensions, units and conversion factors; stoichiometry; sampling and measurements; material balances; thermochemistry; and energy balances. In addition, appendices cover basic properties, graphic and tabular enthalpy data for 65 elements (their oxides halides, carbides and nitrides). This book should be of interest not just to students, but also for practising engineers looking for a refresher text in this important area.
