Chemistry: The Molecular Nature of Matter and Change 6th Edition by Martin Silberberg accommodates unprecedented macroscopic-to-microscopic molecular illustrations, consistent step-by-step worked exercises in each chapter, and an intensive vary of end-of-chapter issues, which offer partaking purposes covering a wide variety of pursuits, including engineering, medicine, materials, and environmental studies.
Modifications have been made to the text and purposes all through to make them extra succinct, to the paintings to make it extra teachable and fashionable, and to the design to make it more simplistic and open. The sixth edition has been modified in some ways to keep pace with the evolution of pupil learning.
Chapter 2 presents a new figure and desk on molecular modeling. Dialogue of empirical formulation has been moved from Chapter 2 to Chapter 3 so it seems just earlier than molecular formulas. Within Chapter 3, some sample issues have been segmented and 7 new pattern issues introduced to raised focus problem-fixing on distinct concepts. Chapter 3 contains extra extensive use of stoichiometry reaction tables in limiting-reactant problems.
Chapter 4 presents a new molecular-scene sample problem on depicting an ionic compound in aqueous solution. Chapter 5 includes a new subsection on how gas laws apply to breathing. Chapter 5 also contains new short discussions on the relevance of gas density. Also in Chapter 5, coverage of reaction stoichiometry has been more logically grouped with other rearrangements of the ideal gas law. Chapter 5 contains new illustrations of diffusion and origin of pressure.
In Chapter 5, Chemical Connections to Atmospheric Science uses the gas laws to explain why the troposphere has a uniform composition. Chapter 7 includes a new sample problem on using the Rydberg equation. Chapter 8 contains a new subsection covering electron configuration, chemical reactivity, and redox behavior. In Chapter 9, Tools of the Laboratory: Infrared Spectroscopy contains a new discussion of carbon dioxide in global warming.
Chapter 11 includes a new discussion of limitations to d-orbital hybridization. Chapter 12 presents new short discussions of everyday applications of surface tension, capillarity, and viscosity. Chapter 13 presents everyday applications of freezing point depression and osmotic pressure. Chapter 14 provides a thorough, focused survey of maingroup descriptive chemistry. Chapter 15 contains new art for the molecular biology of protein synthesis and DNA replication.
Chapter 16 incorporates two of the fifth edition’s boxed features—on measuring reaction rates and on enzymes—into the chapter text. Chapter 17 makes consistent use of benchmarks for determining when an assumption is valid. Chapter 17 incorporates the fifth edition’s boxed feature on ammonia production into the chapter text. Chapter 19 incorporates the fifth edition’s boxed feature on cave formation into the chapter text.
