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.
Modern Computational Quantum Chemistry is indispensable for research in the chemical sciences. Computational Quantum Chemistry II - The Group Theory Calculator describes the group theory that the authors have developed in the past twenty-five years and illustrates how this approach, known as the 'Spherical Shell' method, can be applied to solve a variety of problems that benefit from a group theory analysis. To complement the theory, the book is supplied with a CD-ROM (Windows TM application), on which interactive files, based on EXCEL spreadsheet technology controlled by Visual Basic code, can be used to perform straightforwardly group-theory analyses for direct application to the simplification of physical problems in Chemistry, Physics and even Engineering Science.The Group Theory Calculator Web page is located at http://www.chemistry.nuim.ie/gt_calculator.htm. The primary purpose of this Web page is to identify and resolve any problems encountered while using the MS EXCEL files on the CD-ROM (included with the book). The Web page is maintained by Charles M. Quinn and allows readers to gain updates and news relating to this publication.* A comprehensive description of the authors' revolutionary group theory and structural chemistry methodology* A unique reference/ teaching work together with a CD-ROM filled with powerful interactive files that can be applied to solve group theory problems* Valuable companion for instructors, designers and students* Contains powerful calculators that are simple to use and do not require detailed knowledge for their application
Calculations in Chemistry is intended to help students overcome the challenges associated with solving the numerical problems in chemistry. Chemistry is a numerical science which cannot be fully appreciated without adequate numerical skills. In fact, the lack of problem-solving skills has been recognised as one of the major reasons for the poor performance recorded in the subject over the years. Budgetary and size constraints often translate to lack of space for solving enough sample problems in core textbooks and most problems are presented in a difficult manner that douses enthusiasm for learning. Thus, a book of this nature, containing numerous solved problems drawn from all aspects of chemistry, is necessary to complement the core texts if students are to attain the required level of mastery in the subject. Meant specifically for students studying chemistry at undergraduate and postgraduate levels, this book presents the calculations in chemistry in a simple, logical and down-to-earth manner that will impart students with the required numerical skills for excelling in chemistry. wide topical coverage clear, concise introductions that explain basic principles and theoretical basis for each type of calculation numerous representative examples practice problems and answers to test what has been explained end-of-chapter summary that gives a checklist of key terms and concepts numerous exercises, including objective questions, with answers exhaustive coverage of the mole concept use of SI units and IUPAC conventions it assumes little or no prior knowledge of chemistry and mathematics comprehensive treatment of quantitative analysis appendices that supply useful information
The major goals of quantum chemistry include increasing the accuracy of the results for small molecular systems and increasing the size of large molecules that can be processed, which is limited by scaling considerations-the computation time increases as a power of the number of atoms. This book offers scope for academics, researchers, and engineer
Suitable for all examination specifications for students over 16, this friendly and reliable guide leads students through examples of each problem.
Many undergraduate students enter into chemistry courses from a wide range of backgrounds, often possessing various levels of experience with the mathematical concepts necessary for carrying out practical calculations in chemistry. Chemical Calculations: Mathematics for Chemistry, Second Edition provides a unified, student-friendly reference
This fully revised edition is in line with the revised 2002 National Curriculum requirements and focuses on quantitative chemistry in science. Written to match all major GCSE specifications the text covers all types of numerical questions from first principles. For each topic, a concise treatment of the underlying theory is followed by problems grouped into three sections of increasing difficulty. Calculations based on round number molar masses are included to enable students to concentrate on the chemical basis of the problems rather than arithmetical manipulation.
