This completely updated text and reference is designed to present the fundamental principles of chemistry with strong emphasis on experiments, applications and topics in engineering and the problems created by chemical processes. The three-part structure of the book (Chemistry - I, Chemistry - II, and Chemistry Laboratory) covers more advanced topics in applied chemistry including thermodynamics, polymers, fuel combustion, water treatment and environmental pollution. It can be used by practicing engineers, chemists, and scientists -- or as a text in standard university courses in engineering chemistry, chemical engineering, and chemistry for engineers. Numerous experiments and applications of modern chemical theory, illustrations, in-text examples and exercises have been included.
