Book excerpt: Don't be mixed up about chemistry! Simplify the complex chemical reactions that take place everywhere in our lives with this engaging, easy-to-follow, question-and-answer guide! Where would we be without atoms and compounds? Gas, liquids, solids, and plasma? Acids and bases? Bonds and reactions? Matter and energy? The Handy Chemistry Answer Book covers the building blocks of life and the universe. The secret life of atoms, how polar bears aren’t actually white, why oil and water don't mix, and much, much more are revealed and explained. This informative guide covers the basics of chemistry (history, atomic structures, chemical bonds and reactions, organic and inorganic chemistry) to more advanced material (nuclear chemistry, biochemistry, physical and theoretical chemistry) by answering nearly 1,000 common chemistry questions, including ... What causes lightning? How does photosynthesis work? What are hard and soft Lewis acids and bases? What makes a fabric “waterproof”? What are the twelve principles of green chemistry? When did alchemists finally abandon trying to make gold? What is Le Chatelier’s principle? What do the different octane ratings mean at the gas pump? What is genetic engineering? Why is calcium important for strong bones? What is the 18-electron rule? Why does chocolate turn white as it ages? Chemical reactions that rule the world; their properties, structure, composition, behavior, and history are tackled and explained in plain English in The Handy Chemistry Answer Book. With many photos, illustrations, a few formulas, molecular diagrams, and other graphics, this fun, fact-filled tome is richly illustrated. A history of chemistry timeline, appendices on Nobel Prize in Chemistry winners, a bibliography, further reading section, glossary of terms, a table of physical constants, a table of conversion factors, and extensive index add to its usefulness.
