Offers accurate, lucid, and interesting explanations of basic concepts and facts of chemistry, while helping readers develop skills in analytical thinking and problems solving.
This Third Edition of the widely-used fundamentals textbook for science majors maintains the conversational writing style that made the previous editions so popular, while including up-to-date treatments of important and current topics. Emphasizes descriptive chemistry--chemical reactions and properties--while maintaining a solid treatment of chemical principles. Common chemicals are used, whenever possible, as examples in both theoretical discussions and in problems and exercises. Incorporates many pedagogical aids: each chapter begins with a brief table of contents, and each section begins with a preview of topics covered. Chapters include frequent margin comments, figures, and photographs.
The images on the cover call attention to the relationship between macro observations and the intimate structure of chemical substances and the changes, both chemical and physical, that they undergo. Fireworks: One of the ingredients is phosphorus, a molecular form of which is believed to consist of linked tetrahedra of phosphorus atoms. The chemical reaction of phosphorus with oxygen is partly responsible for the spectacular show of light. Carbon: The element is found in several forms, including the familiar diamond and another, recently discovered, sooty substance that consists of soccer-ball shaped molecules, often referred to as "buckeyballs." Diamond is not the most stable form of carbon and is created from other forms of carbon at high temperatures and pressures deep within the earth. Acetylene torch: Cutting steel is possible because of the intense heat generated by the chemical reaction of acetylene with oxygen, a reaction between molecules of C_2H_2 and O_2 to give CO_2 and H_2O. Hot air balloon: The air that helps it rise is heated by the combustion of molecules of propane, each composed of three carbon and eight hydrogen atoms. Stormy weather: The evaporation of water serves to store energy provided by the sun. Subsequent condensation of the water vapor releases this energy and is the basis of all the weather systems on our planet.
This updated editon explains recent advances in environmental studies and in the molecular basis of life. Suitable for students interested in the health care field as well as those who want to know how nature and human life work at the molecular level, the book begins by providing readers with a solid background in formulas, structures, equations, solutions and equilibria. A number of topics are introduced early, such as molarity, and are discussed in more detail in later chapters. Each chapter contains a summary as well as review exercises.
