This text is a chemistry problem solving resource appropriate for teachers and their students who are enrolled in high school Advanced Placement Chemistry or in a first-year college General Chemistry course. The book incorporates a chemistry problem solving plan, one that uses an innovative graphic organizer strategy. The strategy - successfully evaluated with students - combines problem solving processes with chemical concepts that will allow students to solve the most common and difficult problems encountered in the first year of chemistry. Topical problem solving will focus on limiting reactant stoichiometry, identifying types of chemical reactions, equilibrium, acid-base equilibria, and electrochemistry.Why would this resource be of interest to chemistry students? To be successful (to ...

Chemistry is a human endeavor that relies on basic human qualities like creativity, insights, reasoning, and skills. It depends on habits of the mind: skepticism, tolerance of ambiguity, openness to new ideas, intellectual honesty, curiosity, and communication. Young female students begin studying chemistry curiosity; however, when unconvinced, they become skeptical. Researches focused on gender studies have indicated that attitudes toward science education differ between males and females. A declining interest in chemistry and the under representation of females in the chemical science was found (Jacobs, 2000). This study investigated whether self-confidence toward chemistry, the influence of role models, and knowledge about the usefulness of chemistry were affecting the attitudes toward...

Problems in Organic Chemistry: A Self-Study Guide is the only undergraduate organic chemistry book to use a lead oriented-incremental approach. It aids and reinforces learning by encouraging students to connect sometimes disparate facts and theories in order to solve problems. The approach uniquely complements the lecture material by building concepts sequentially within a problem-solving context. The book is organized into three major sections: problems; lead-oriented cumulative verbal statements; and detailed solutions with structures and in-depth explanations.

Learn not only how to recreate the chemicals that changed history, but the history behind the chemicals. A five star college level teaching aid! Half a million years ago our ancestors learned to make fire from scratch. They crafted intricate tools from stone and brewed mind-altering elixirs from honey. Their descendants transformed clay into pottery, wool into clothing, and ashes into cleansers. In ceramic crucibles they won metal from rock, the metals lead to colored glazes and glass. Buildings of brick and mortar enshrined books of parchment and paper. Kings and queens demanded ever more colorful clothing and accessories in order to out-class clod-hoppers and call-girls. Kingdoms rose and fell by the power of saltpeter, sulfur, and charcoal. And the demands of everyday folk for glass ...

This unique book of real chemistry and science for children illustrates the nature of physical and chemical change using the very smallest parts of things: atoms and molecules. It encourages children, ages 5-12, along with their parents or teachers, to become active learners of science, to discover meaning not only in the ideas and definitions of others, but also (and especially) in their own world. Chapters include: Evaporating, Condensing, Dissolving, Crystallizing, Mixing, Separating, Melting, Freezing, and Reacting.

This book is for chemistry teachers who are thinking about reinventing their laboratory experiments that they provide to their students. More than a collection of experiments, it is an example of using a chemical theme to teach chemistry. Instead of introducing many different chemicals per experiment as is the norm in most lab manuals, this novel resource focuses on two commonly found elements: Zinc and Iodine.So what is so special about these elements? At the heart of this resource is a colorful cyclic reaction between zinc and iodine, one that produces a compound that can decompose back to its original elements. This unique phenomenon demonstrates that matter not only changes, but is also conserved through a chemical reaction. Knowing that a compound can be the "same but different" than ...

Many people don't understand why black lives must matter and why the racial divide seems to be taking the country back 50 years. Like the mythical Sankofa bird, the answer to what's missing now lies in what existed before. Our Fathers: Making Black Men focuses on one block of St. Louis in the mid-20th century, where African American businessmen living the American Dream also created a sense of community for boys in that neighborhood. Lincoln I. Diuguid, a PhD graduate of Cornell University in chemistry, anchored the block with Du-Good Chemical Laboratories & Manufacturers. The chemistry the book reveals isn't rocket science, it's just the lost formula of community engagement. Men like Doc gave boys on the street jobs and a strong work ethic. They did it through sharing the African American...

The fundamental aspects of classical thermodynamics are presented in a simple compact way. The equations derived are illustrated by numerous (111) examples, often direct application of the relations just obtained. The (four) laws of thermodynamics are presented and illustrated. The need to define thermodynamic temperature, the meaning of auxiliary thermodynamic functions, the origin, usefulness and use of partial molar quantities are all examined. Gaseous systems, phase equilibria and chemical reactions are quantitatively treated. It is shown how chemical reactions can provide work. Ideal and non ideal solutions are presented with the various standard states and activity coefficients. This book will be of use to a wide audience of students and professionals in the fields of Chemistry,...

In this volume (volume 1), the tools necessary to study and understand systems in which chemical reactions can take place are developed. The variables of reaction are the keys to this understanding. Criteria for chemical equilibrium are established. It is shown how chemical reactions can provide work as, for example, in batteries. For complex systems, the number of independent reactions and their nature have to be determined systematically. The effect of external factors on chemical equilibria is analyzed and illustrated. The formalism necessary to study ideal and real solutions is provided. The various standard states in use and the corresponding activity coefficients are clearly defined. In volume 2, the tools necessary to study and understand systems in which chemical reactions can t...

Comets have not only blazed across the celestial vault throughout human history, they have embellished the night sky since the Earth itself formed some 4.5 billion years ago. Comets were among the first-born solid bodies in the solar system, and their frozen nuclei tell of the primordial chemistry and chaos that ultimately resulted in the formation of the planets, the evolution of life and us. For all this, however, comets have long been celestial oddities: they baffled our distant ancestors, and human society continues to marvel and speculate wildly at their appearance even to the present day. Cutting against the perceived constancy of the stars, comets seemingly present themselves at random times and they are often interpreted as harbingers of terrestrial change - both good and ill. How ...

For the first time in science education, the subject of multiple solution methods is explored in book form. While a multiple method teaching approach is utilized extensively in math education, there are very few journal articles and no texts written on this topic in science. Teaching multiple methods to science students in order to solve quantitative word problems is important for two reasons. First it challenges the practice by teachers that one specific method should be used when solving problems. Secondly, it calls into question the belief that multiple methods would confuse students and retard their learning. Using a case study approach and informed by research conducted by the author, this book claims that providing students with a choice of methods as well as requiring additional met...

From his childhood, Steiner already possessed the ability to perceive the supersensible-to see the reality of the spiritual world with the same clarity and certainty as he saw the physical. As he matured, he felt a profound need to bring a discipline to his supersensible discoveries-to develop a methodology equal to what the natural science of his day demanded. While earning degrees in mathematics, physics and chemistry at the Technical University in Vienna, he began developing an approach to a systematic research of psychological and spiritual phenomena. His doctoral thesis "Truth and Knowledge" was followed, in 1894, by "The Philosophy of Freedom", a seminal work in which Steiner established a firm foundation for a science of the supersensible. Most of us, I believe, view our day t...

This book explores the science of extraterrestrial life, with a particular emphasis on the existence of intelligent alien civilizations. It introduces the reader to the basic chemistry associated with life on Earth and describes the planetary and stellar environments that allow us to exist. It also discusses the likelihood of alien life developing at other locations in our galaxy, along with the possibility that we will meet or communicate with them. This book is suitable for use as a text in an introductory "Life in the Universe" course.

This book looks at fresh (fruits and vegetables) and processed foods from a biochemical and nutritional perspective, as well as the relationship between their content in micronutrients and phytochemicals and the major killer diseases such as cardiovascular disease, diabetes and cancer. The book also pays special attention to two important topics not addressed by other texts on nutrition, namely low-grade systemic inflammation and caloric restriction, which were consistently shown to impact health and disease. Caloric restriction can help in weight reduction programs and in slowing down age-associated degenerative disorders. In contrast to other texts on a similar topic, this book is a blend of nutrition, biochemistry and pathology. More specifically, we discuss the molecular mechanisms in...

Does the field of evolution differ from other sciences? The author, a reviewer for a major medical journal, scrutinized hundreds of scientific references in evolutionary literature, adopting the same standards used for studies submitted for medical publication. The data show that there are two types of evolution, microevolution and macroevolution, with a clear boundary between them based upon the presence and absence of empirical evidence, respectively. The surprising results show that there is a universal disconnect between the data and the conclusions that claim to show the larger changes of macroevolution. The author reveals patterns of deviations from standard scientific methods in these studies. For the first time, evolutionary data have been summarized to describe both what evolution...

Plant cell walls are composed of complex carbohydrates, proteins, phenolic compounds, and inorganic ions, all of which play functional roles. Cellulose (1,4-beta-glucan) and callose (1,3-beta-glucan) are synthesized in the plasma membrane, while other polysaccharides are synthesized in the Golgi. Plant cell growth occurs with the loosening of the walls, which may be caused by several enzymatic actions. Plant development is related to the morphological changes of cells and tissue, which is caused by structural changes of the walls. This remarkable collection presents the latest understanding of plant cell walls and cellulose synthesis from some of the world's best and most promising researchers. The book is divided into eight sections describing: Cell Wall Structure, Biosynthesis, Cell W...
