Chemistry 2e


Book Description

Chemistry 2e is designed to meet the scope and sequence requirements of the two-semester general chemistry course. The textbook provides an important opportunity for students to learn the core concepts of chemistry and understand how those concepts apply to their lives and the world around them. The book also includes a number of innovative features, including interactive exercises and real-world applications, designed to enhance student learning. The second edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Substantial improvements have been made in the figures, illustrations, and example exercises that support the text narrative. Changes made in Chemistry 2e are described in the preface to help instructors transition to the second edition.







The Chemical Equilibrium of Gaseous Systems


Book Description

It is the purpose of this book to present a concise and sufficiently detailed de scription of the present state and possibilities of calculating chemical equilibria of gas mixtures. It is based on a book by one of the authors, published in Czech by the Publishing House Academia in Prague. The rapid development of the topic during the two years since publication of the Czech edition has made it necessary to revise practically all the sections in order to bring them up to the present level of know ledge. One reason for writing this book was the practical requirement of contemporary industry, where a rational utilization of equilibrium composition calculations may provide valuable information concerning processes under study in all stages of their implementation. A second reason was the need of a text-book for studying this part of chemical thermodynamics in the scope as taught at the Institute of Chemical Technology, Prague. These two basic motives determine the overall structure of the book, as well as the proportions and arrangement of the chapters. The book includes fundamental thermodynamic concepts as well as the mathematical apparatus needed to solve the problems involved, care being taken that the discussion should always l!!ad to a practical procedure of performing equilibrium calculations in gas-phase systems of any degree of complexity whatever. Knowledge of chemical thermodynamics on the level of a fundamental university course is assumed.




The Computation of Chemical Equilibria


Book Description

This 1970 book, the authors derive the equations describing equilibria in different types of system and outline the effect of variation of the parameters of the system on the equilibrium composition by using equilibrium calculations in high temperature, high pressure processes, in rocketry and in explosives technology.







Equilibrium Calculation in the System


Book Description

A set of equations was written which allowed the calculation of equilibrium concentrations in the solvent phase of nitric acid and uranyl nitrate, given the initial TBP concentration in the solvent and the aqueous phase concentrations of acid and uranium. An ORACLE subroutine was written based on these equations which will calculate a set of equilibrium values in about 35 milliseconds. The subroutine was incorporated into a short program to calculate equilibrium points. A set of calculated points are presented in graphical form for 5, up to 7 M and uranyl nitrate concentrations up to 0.6 M in the aqueous phase. Since these calculations were based on limited data, it is the purpose of this memo to invite comment on their accuracy. The equations were reworked from a Russian paper by A.M. Rozen and L.P. Khorkhorina, using emperical polynomial fits for some poorly defined parameters, and were based principally on data from J.W. Codding. This project was undertaken to provide a subroutine to calculate equilibria in a general purpose ORACLE program to calculate the performance of multi-stage compound extraction cascades with more than one significant solute.

Chemistry


Book Description

Steve and Susan Zumdahl's texts focus on helping students build critical thinking skills through the process of becoming independent problem-solvers. They help students learn to "think like a chemists" so they can apply the problem solving process to all aspects of their lives. In CHEMISTRY: AN ATOMS FIRST APPROACH, 1e, International Edition the Zumdahls use a meaningful approach that begins with the atom and proceeds through the concept of molecules, structure, and bonding, to more complex materials and their properties. Because this approach differs from what most students have experienced in high school courses, it encourages them to focus on conceptual learning early in the course, rather than relying on memorization and a "plug and chug" method of problem solving that even the best students can fall back on when confronted with familiar material. The atoms first organization provides an opportunity for students to use the tools of critical thinkers: to ask questions, to apply rules and models and to




A Problem-Solving Approach to Aquatic Chemistry


Book Description

A Problem-Solving Approach to Aquatic Chemistry Enables civil and environmental engineers to understand the theory and application of aquatic equilibrium chemistry The second edition of A Problem-Solving Approach to Aquatic Chemistry provides a detailed introduction to aquatic equilibrium chemistry, calculation methods for systems at equilibrium, applications of aquatic chemistry, and chemical kinetics. The text directly addresses two required ABET program outcomes in environmental engineering: “… chemistry (including stoichiometry, equilibrium, and kinetics)” and “material and energy balances, fate and transport of substances in and between air, water, and soil phases.” The book is very student-centered, with each chapter beginning with an introduction and ending with a summary that reviews the chapter’s main points. To aid in reader comprehension, important terms are defined in context and key ideas are summarized. Many thought-provoking discussion questions, worked examples, and end of chapter problems are also included. Each part of the text begins with a case study, a portion of which is addressed in each subsequent chapter, illustrating the principles of that chapter. In addition, each chapter has an Historical Note exploring connections with the people and cultures connected to topics in the text. A Problem-Solving Approach to Aquatic Chemistry includes: Fundamental concepts, such as concentration units, thermodynamic basis of equilibrium, and manipulating equilibria Solutions of chemical equilibrium problems, including setting up the problems and algebraic, graphical, and computer solution techniques Acid–base equilibria, including the concepts of acids and bases, titrations, and alkalinity and acidity Complexation, including metals, ligands, equilibrium calculations with complexes, and applications of complexation chemistry Oxidation-reduction equilibria, including equilibrium calculations, graphical approaches, and applications Gas–liquid and solid–liquid equilibrium, with expanded coverage of the effects of global climate change Other topics, including chemical kinetics of aquatic systems, surface chemistry, and integrative case studies For advanced/senior undergraduates and first-year graduate students in environmental engineering courses, A Problem-Solving Approach to Aquatic Chemistry serves as an invaluable learning resource on the topic, with a variety of helpful learning elements included throughout to ensure information retention and the ability to apply covered concepts in practical settings.
