This study guide for the Chemistry Olympiad contains summarized concepts and examples in all areas of chemistry. The chapters are arranged in a logical manner and establishes connections between concepts. Undergraduate chemistry concepts are explained clearly: every equation in physical chemistry is derived and justified while every organic reaction has its reaction mechanism shown and explained, without assuming that readers have university-level background in the subject. The book also contains original Chemistry Olympiad sample problems that readers may use to test their knowledge.This is a first book of its kind, written by Nan Zhihan, International Chemistry Olympiad (IChO) gold medallist and winner of the International Union of Pure and Applied Chemistry (IUPAC) Prize for achieving the highest score in the experimental exam, and experienced Chemistry Olympiad trainer Dr Zhang Sheng, who has served as head mentor of Singapore IChO team for many years. It builds on the experience of both a participant and trainer to help any aspiring Chemistry Olympiad student understand the challenging concepts in chemistry.

Chemical Structure and Reactivity: An Integrated Approach rises to the challenge of depicting the reality of chemistry. Offering a fresh approach, it depicts the subject as a seamless discipline, showing how organic, inorganic, and physical concepts can be blended together to achieve the common goal of understanding chemical systems.

This book is part of a series of Chemistry Olympiad - A problem-solving approach. This book aims to provide a problem-solving approach to the questions in Chemistry Olympiad, a different take to Chemistry Olympiad as opposed to the routine memorisation and heavy content provided in other books. I plan to make a series of these books for various other chapters such as kinetics, organic chemistry, inorganic elucidation etc. if this book gains any form of traction.The books would be separated into 3 main chapters: Fundamentals, Problem-solving approach, Tips & tricks. The first chapter will provide you with the necessary knowledge to solve the problems you will face in Chemistry Olympiad. In the next chapter, we will go through some techniques used to solve problems. There would be problems of which you may choose to do before reading the solutions in this chapter. The solutions will include guided techniques to tackling such problems along with in depth analysis and explanation of the questions. Lastly, the final chapter, would comprise of tips I have picked up along the way which will help increase your speed in doing problems and general advice.I graduated from NUS High (Singapore) in 2019 with High Distinction with Honours in Mathematics and Chemistry, and Majors in Biology and Physics. I participated in the International Chemistry Olympiad (IChO) representing Singapore in 2019 and attained a gold medal when I was 18 years old.The idea for the book came out of boredom due to COVID-19. ㈵0;

Written for calculus-inclusive general chemistry courses, Chemical Principles helps students develop chemical insight by showing the connections between fundamental chemical ideas and their applications. Unlike other texts, it begins with a detailed picture of the atom then builds toward chemistry's frontier, continually demonstrating how to solve problems, think about nature and matter, and visualize chemical concepts as working chemists do. Flexibility in level is crucial, and is largely established through clearly labeling (separating in boxes) the calculus coverage in the text: Instructors have the option of whether to incorporate calculus in the coverage of topics. The multimedia integration of Chemical Principles is more deeply established than any other text for this course. Through the unique eBook, the comprehensive Chemistry Portal, Living Graph icons that connect the text to the Web, and a complete set of animations, students can take full advantage of the wealth of resources available to them to help them learn and gain a deeper understanding.

The object of this book is to provide an introduction to electro chemistry in its present state of development. An attempt has been made to explain the fundamentals of the subject as it stands today, de voting little or no space to the consideration of theories and arguments that have been discarded or greatly modified. In this way it is hoped that the reader will acquire the modern point of view in electrochemistry without being burdened by much that is obsolete. In the opinion of the writer, there have been four developments in the past two decades that have had an important influence on electrochemistry. They are the ac tivity concept, the interionic attraction theory, the proton-transfer theory of acids and bases, and the consideration of electrode reactions as rate processes. These ideas have been incorporated into the structure of the book, with consequent simplification and clarification in the treatment of many aspects of electrochemistry. This book differs from the au thors earlier work, The Electrochem istry of Solutions in being less comprehensive and in giving less detail. While the latter is primarily a work of reference, the present book is more suited to the needs of students of physical chemistry, and to those of chemists, physicists and physiologists whose work brings them in con tact with a variety of electrochemical problems. As the title implies, the book should also serve as an introductory text for those who in tend to specialize in either the theoretical or practical applications of electrochemistry. In spite of some lack of detail, the main aspects of the subject have been covered, it is hoped impartially and adequately. There has been some tendency in recent electrochemical texts to pay scant attention to the phenomena at active electrodes, such as ovcrvoltage, passivity, cor rosion, deposition of metals, and so on. These topics, vihich are of importance in applied electrochemistry, are treated here at Mich length as seems reasonable. In addition, in view of tho growing interest in electrophoresis, and its general acceptance as a branch of electrochem istry, a chapter on clectrokinetic phenomena has boon included. No claim is made to anything approaching completeness in the matter of references to the scientific literature. Such reformers as arc given arc generally to the more recent publications, to review articles, and to papers that may, for one reason or another, have some special interest. References are also frequently included to indicate the sources from which data have been obtained for many of the diagrams and tables. Since no effort was made to be exhaustive in this connection, it was felt that an author index would be misleading...

Number theory is an important research field of mathematics. In mathematical competitions, problems of elementary number theory occur frequently. These problems use little knowledge and have many variations. They are flexible and diverse. In this book, the author introduces some basic concepts and methods in elementary number theory via problems in mathematical competitions. Readers are encouraged to try to solve the problems by themselves before they read the given solutions of examples. Only in this way can they truly appreciate the tricks of problem-solving.

The essential, cornerstone book of modern environmentalism is now offered in a handsome 40th anniversary edition which features a new Introduction by activist Terry Tempest Williams and a new Afterword by Carson biographer Linda Lear.

Chemistry textbook for high school.

Friendly Chemistry is a truly unique approach to teaching introductory chemistry. Used by home schoolers and charter, public and private school students world-wide for over ten years, Friendly Chemistry presents what is often considered an intimidating subject as a genuinely fun, enjoyable experience. Whether you're a high-school aged student needing a lab science course or a "non-traditional" student looking for a refresher course to help you prepare for an upcoming entrance exam, Friendly Chemistry can help you accomplish your goal in a "painless" way! If you do have aspirations of a future in a science field, Friendly Chemistry can give you the solid foundation you need to succeed in subsequent courses.Friendly Chemistry was written using simple language and a host of analogies to make learning (and teaching!) chemistry easy. The chemistry concepts presented in Friendly Chemistry are NOT watered-down. The concepts are just explained in ways that are readily understood by most learners. Coupled with these explanations is a host of teaching aids, labs and games which makes the learning concrete and multi-sensory. Students find the course fun and painless. Parents often comment, "I wish I had had this when I was taking chemistry. Now it all makes so much sense!" Friendly Chemistry covers the same topics taught in traditional high school chemistry courses. The course begins with an introduction to atomic theory followed by discussion of why the elements are arranged the way they are in the periodic table. Quantum mechanics comes next using the acclaimed "Doo-wop" Board as a teaching aid. Next comes a discussion of how atoms become charged (ionization), followed by an explanation of how charged atoms make compounds. The mole is introduced next, followed by a discussion of chemical reactions. Stoichiometry (predicting amounts of product produced from a reaction) is treated next followed by a discussion of solutions (molarity). The course is wrapped up with a discussion of the ideal gas laws. Please note that this is the STUDENT EDITION. Volumes 1 and 2 of the TEACHER"S EDITION must be purchased separately in order to have all materials necessary to complete this chemistry course.
