All the fundamental topics of general chemistry are presented in this brief, cost-effective, student- oriented text. Masterton/Hurley's CHEMISTRY: PRINCIPLES AND REACTIONS, 6e, provides a clear, concise presentation based on the authors' more than 50 years of combined teaching experience. This edition takes students directly to the crux of concepts with brevity that gives you the flexibility to cover all topics found in the typical general chemistry book as well as areas such as nuclear chemistry, organic topics, and descriptive chemistry. This edition includes an increased variety and number of applications, as well as more concept-driven, rigorous examples and examples that focus on molecular reasoning and understanding. New "Chemistry: Beyond the Classroom" essays by guest authors demonstrate the relevance of concepts to your students while highlighting some of the latest state-of-the-art uses of chemistry today. A strong, enhanced art program further assists students in visualizing chemical concepts. For the first time, this edition fully integrates OWL (Online Web-based Learning), the homework management system trusted by more than 300 institutions and tens of thousands of students. Integrated end-of-chapter questions appear in OWL and correlate to Key Concepts. An optional e-book of this edition is also available in OWL. To further assist in learning and depth of coverage, the book offers CengageNOW™, an innovative Web-based student self-tutorial program. In addition, Go Chemistry™ video study modules developed by award-winning chemists offer mini-lectures and learning tools available for video iPods, MP3 players, and iTunes for students on the go.
