Why Study Chemistry

By studying chemistry, you will learn to use the powerful language and ideas that have evolved to describe and enhance our understanding of matter. Furthermore, an understanding of chemistry provides powerful insights into other areas of modern science, technology, and engineering. [Pg.6]

Vast amounts of chemicals are produced each year and serve as raw materials for a variety of uses, including the manufacture and processing of metals, plastics, fertilizers, pharmaceuticals, fuels, paints, adhesives, pesticides, synthetic fibers, and microprocessor chips. T TABLE 1.1 lists the top eight chemicals produced in the United States. [Pg.6]

Nonetheless, he continues to actively pursue new projects, welcoming new students into the group and pushing forward. Why do we study chemistry he asks. We want to know answers to qualitative questions. That is what distinguishes us from physics. ... [Pg.357]

Why study short-lived molecules Those who carry out such studies are perhaps driven by two main ambitions. First, to investigate the structures of compounds with unusual coordination numbers or oxidation states. We can thus make small molecules, for example, AlCl or OPCl (to take just two of very many examples), that are not stable under ambient conditions. In transition metal chemistry, it is becoming apparent that we caimot predict the structures of open shell molecules simply by looking at the structures of closed shell species, for example, we caimot predict what structure the unsaturated 16-electron carbonyl Cr(CO)s will adopt, simply by knowing that saturated 18-electron Cr(CO)6 is octahedral. The second point is to study reaction mechanism. We must know about stmctures of intermediates fully to understand reaction pathways kinetics alone is not enough. [Pg.4374]

Chemistry makes connections among the composition, structure, and behavior of matter. As you study chemistry, you will learn how the chemical and physical properties of matter are important clues to its submicro-scopic structure and behavior. You U see how knowing the structure of an atom of an element can enable you to predict the chemical behavior of that element. You U learn how the state of a substance at room temperature provides clues to the way its atoms are arranged. You ll find out why some things dissolve in water but others do not, how metals corrode, how batteries work, why compounds containing carbon are important to life, and how a nuclear reactor works. [Pg.44]

At the upper secondary level, beyond the age of compulsory schooling, chemistry courses tend to differentiate into those for specialists ( science majors ) and for non-specialists. For non-specialists, a context-based course seems the only logical approach if they are studying chemistry, why not base it on contexts that are relevant to them An example of such a course is provided by ChemCom (American Chemical Society, 2001a). While this course claims to provide a foundation for further study of chemistry, it omits some of the content, such as orbitals, calculations dealing with equilibrium constants, and kinetics that would be found in a traditional chemistry course at this level in the US. [Pg.169]

In systems containing several complexing elements, even with simultaneous application of several experimental methods, as a regular rule, it is impossible to determine the concentration of all present stable migration forms. Efficiency of such analytical methods, as a regular rule, declines with a decrease in stability of the migration forms themselves. In studies of the form whose stability constants are close to 1, these methods are ineffective. That is why in chemistry of complex compounds along with experimental methods are widely utilized theoretical calculation methods. [Pg.432]

What s inside of a zit Why does eating turkey make you sleepy How do glow sticks work What causes a hangover Chemistry (and this book ) holds answers to all of these questions. There are many wonderful stories about chemistry and the people behind these discoveries. Whether you have studied chemistry in high school or college, or even do chemistry for a living, we think you will enjoy this book. We certainly enjoyed writing it. [Pg.401]

If you look carefully at the reactions we ve been writing, you ll notice more than just the formulas and the states of the substances in the equation. Numerical information about the relative amounts of the substances involved is also evident. For example, we included the number 2 in front of both the H2(g) and H20(g) in the equation for the reaction between hydrogen and oxygen. Why are these numbers there, and what do they mean If you ve studied chemistry before in high school, you probably remember that these coefficients are often needed to balance a chemical equation. [Pg.83]

B There is nothing wrong with spending as little time as possible studying chemistry, as long as you leam the needed amount of chemistry in the time spent. Soon we ll show why the amount of time required to learn (not just study) chemistry depends on when you study and learn. They should occur simultaneously. Reducing the time required to complete any task satisfactorily is a worthy objective. It even has a name efficiency. [Pg.8]
