College freshmen who want to understand chemical calculations from the basics will also find many of the chapters in this book helpful toward their courses. Hundreds of solved examples as well as challenging end-of-chapter exercises are some of the great features of this book. . Students studying for SAT I & II, GCSE, IGCSE, UTME, SSCE, HSC, and other similar examinations will benefit tremendously by studying all the chapters in this book conscientiously.
Ab Initio Valence Calculations in Chemistry describes the theory and practice of ab initio valence calculations in chemistry and applies the ideas to a specific example, linear BeH2. Topics covered include the Schrödinger equation and the orbital approximation to atomic orbitals; molecular orbital and valence bond methods; practical molecular wave functions; and molecular integrals. Open shell systems, molecular symmetry, and localized descriptions of electronic structure are also discussed. This book is comprised of 13 chapters and begins by introducing the reader to the use of the Schrödinger equation to solve the electronic structure of molecular systems. This discussion is followed by two chapters that describe the chemical and mathematical nature of orbital theories in quantum chemistry. Two general ways of using chemical and physical information in looking for approximate solutions of the Schrödinger equation are highlighted: model approximations and numerical approximations. Attention then turns to atomic orbitals as the basis of a description of molecular electronic structure; practical molecular wave functions; and a general strategy for performing molecular valence calculations. The final chapter examines the nature of the valence electronic structure by using invariance with respect to transformations among the occupied molecular orbitals and among the atomic orbitals. This text will be of interest to students and practitioners of chemistry, biochemistry, and quantum mechanics.

Ever thought there could be an easy way to master calculations in chemistry? Well, this book takes a practical and common sense approach to calculations in chemistry. Learners from GCSE/O'Levels right through to A Levels will find this book very indispensable as it covers calculations from the basics, starting from the building blocks of matter down to more complicated calculations in chemistry. This book touches on nearly all types of calculation you could come across in secondary school right up to second year in the university or college, gradually building up on the learners basic understandings of the inner workings of the subject.
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 of mathematical concepts and techniques incorporated into the context of familiar chemical topics. Uniquely organized by chemical—rather than mathematical—topics, this book relates each mathematical technique to the chemical concepts where it applies. The new edition features additional, revised, and updated material in every chapter. It achieves greater clarity with newly improved organization of topics and cross-referencing where mathematical techniques occur more than once. The text also contains numerous worked examples along with end-of-chapter exercises and detailed solution—giving students the opportunity to apply previously introduced techniques to chemically related problems. An ideal course companion for chemistry courses throughout the length of a degree, the second edition of Chemical Calculations: Mathematics for Chemistry may also extend its utility as a concise and practical reference for professionals in a wide array of scientific disciplines involving chemistry.
It is now possible to enter a chemistry degree course at many UKuniversities without any formal maths training beyond age 16.Addressing this deficiency requires students to take additionalmathematics training when entering university, yet the relevance ofmaths to chemistry is often poorly appreciated by chemistrystudents. In addition, many service courses are either tooabstract, or aimed at physicists and engineers, for students ofchemistry, who are not inclined to study mathematical techniquesper se and do not make the connection between the maths theyare taught and the chemistry they want to study. Based on the successful at a Glance approach, withintegrated double page presentations explaining the mathematicsrequired by undergraduate students of chemistry, set in context bydetailed chemical examples, this book will be indispensable to allstudents of chemistry. By bringing the material together in thisway the student is shown how to apply the maths and how it relatesto familiar concepts in chemistry. By including problems (withanswers) on each presentation, the student is encouraged topractice both the mathematical manipulations and the application toproblems in chemistry. More detailed chemical problems at the endof each topic illustrate the range of chemistry to which the mathsis relevant and help the student acquire sufficient confidence toapply it when necessary.
Concepts & Calculations in Analytical Chemistry: A Spreadsheet Approach offers a novel approach to learning the fundamentals of chemical equilibria using the flexibility and power of a spreadsheet program. Through a conceptual presentation of chemical principles, this text will allow the reader to produce and digest large assemblies of numerical data/calculations while still focusing on the chemistry. The chapters are arranged in a logical sequence, identifying almost every equilibrium scenario that an analytical chemist is likely to encounter. The spreadsheet calculations and graphics offer an excellent solution to otherwise time-consuming operations. Worked examples are included throughout the book, and student-tested problems are featured at the end of each chapter. Spreadsheet commands for QuattroPro, Quattro, and Lotus 1-2-3 are embedded in the text. Concepts & Calculations in Analytical Chemistry: A Spreadsheet Approach has been designed to serve both as a supplement to an undergraduate quantitative analysis course or as a text in a graduate-level advanced analytical chemistry course. Professional chemists will also find this to be an excellent introduction to spreadsheet applications in the lab and a modern overview of analytical chemistry in a self-study format.

Problem-solving is one of the most challenging aspects students encounter in general chemistry courses leading to frustration and failure. Consequently, many students become less motivated to take additional chemistry courses after the first year. This book deals with calculations in general chemistry and its primary goal is to prevent frustration by providing students with innovative, intuitive, and systematic strategies to problem-solving in chemistry. The material addresses this issue by providing several sample problems with carefully explained step-by-step solutions for each concept. Key concepts, basic theories, and equations are provided and worked examples are selected to reflect possible ways problems could be presented to students.
Presenting an account of the concepts that underly different approaches devised for the determination of free energies, this book aims to give the reader, an insight into the theoretical and computational foundations of the subject. It is aimed at students and researchers having a background in chemistry, physics, engineering and physical biology.
