1. Table of Contents

The first essential in chemistry is that you should perform practical work and conduct experiments, for he who performs not practical work nor makes experiments will never attain the least degree of mastery.

JBIR IBN HAYYN, 8TH CENTURY

One of the wonders of this world is that objects so small can have such consequences: Any visible lump of matter even the merest speck contains more atoms than there are stars in our galaxy.

PETER W. ATKINS, 20TH CENTURY

Chemistry is at once practical and wondrous, humble and majestic. And for someone studying it for the first time, chemistry can be tricky.

Thats why we wrote this book. Chemistry is wondrous. Workbooks are practical. Practice makes perfect. This chemistry workbook will help you practice many types of chemistry problems with the solutions nicely laid out.

When youre fixed in the thickets of stoichiometry or bogged down by buffered solutions, youve got little use for rapturous poetry about the atomic splendor of the universe. What you need is a little practical assistance. Subject by subject, problem by problem, this book extends a helping hand to pull you out of the thickets and bogs.

The topics covered in this book are the topics most often covered in a first-year chemistry course in high school or college. The focus is on problems problems like the ones you may encounter in homework or on exams. We give you just enough theory to grasp the principles at work in the problems. Then we tackle example problems. Then you tackle practice problems. The best way to succeed at chemistry is to practice. Practice more. And then practice even more. Watching your teacher do the problems or reading about them isnt enough. Michael Jordan didnt develop a jump shot by watching other people shoot a basketball. He practiced. A lot. Using this workbook, you can, too (but chemistry, not basketball).

This workbook is modular. You can pick and choose those chapters and types of problems that challenge you the most; you dont have to read this book cover to cover if you dont want to. If certain topics require you to know other topics in advance, we tell you so and point you in the right direction. Most importantly, we provide a worked-out solution and explanation for every problem.

We assume you have a basic facility with algebra and arithmetic. You should know how to solve simple equations for an unknown variable. You should know how to work with exponents and logarithms. Thats about it for the math. At no point do we ask you to, say, consider the contradictions between the Schrdinger equation and stochastic wavefunction collapse.

We assume youre a high school or college student and have access to a secondary school-level (or higher) textbook in chemistry or some other basic primer, such as Chemistry For Dummies, 2nd Edition (written by John T. Moore, EdD, and published by Wiley). We present enough theory in this workbook for you to tackle the problems, but youll benefit from a broader description of basic chemical concepts. That way, youll more clearly understand how the various pieces of chemistry operate within a larger whole youll see the compound for the elements, so to speak.

We assume you dont like to waste time. Neither do we. Chemists in general arent too fond of time-wasting, so if youre impatient for progress, youre already part-chemist at heart.

Youll find a selection of helpful icons nicely nestled along the margins of this workbook. Think of them as landmarks, familiar signposts to guide you as you cruise the highways of chemistry.

Within already pithy summaries of chemical concepts, passages marked by this icon represent the pithiest must-know bits of information. Youll need to know this stuff to solve problems.

Sometimes theres an easy way and a hard way. This icon alerts you to passages intended to highlight an easier way. Its worth your while to linger for a moment. You may find yourself nodding quietly as you jot down a grateful note or two.
