Suitable for all examination specifications for students over 16, this friendly and reliable guide leads students through examples of each problem.

This textbook has been updated to cover the new specifications for AS and A2 Chemistry, and improved with new features and rewritten material to enhance learning and increase accessibility. It covers all the main specifications for the English and Welsh Awarding Bodies, and should be particularly suitable for students approaching A-Level from GCSE Science: Double Award. This answer key is designed to support the core book and contains suggested answers, worked solutions to the checkpoints and examination questions in the core book, also synoptic questions for further practice, complete with suggested answers and worked solutions, to help develop confidence.

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

Free energy constitutes the most important thermodynamic quantity to understand how chemical species recognize each other, associate or react. Examples of problems in which knowledge of the underlying free energy behaviour is required, include conformational equilibria and molecular association, partitioning between immiscible liquids, receptor-drug interaction, protein-protein and protein-DNA association, and protein stability. This volume sets out to present a coherent and comprehensive account of the concepts that underlie different approaches devised for the determination of free energies. The reader will gain the necessary insight into the theoretical and computational foundations of the subject and will be presented with relevant applications from molecular-level modelling and simulations of chemical and biological systems. Both formally accurate and approximate methods are covered using both classical and quantum mechanical descriptions. A central theme of the book is that the wide variety of free energy calculation techniques available today can be understood as different implementations of a few basic principles. The book is aimed at a broad readership of graduate students and researchers having a background in chemistry, physics, engineering and physical biology.
