A round-the-globe journey through the periodic table explains how the air people breathe reflects the world's history, tracing the origins and ingredients of the atmosphere to explain air's role in reshaping continents, steering human progress, and powering revolutions. "The fascinating science and history of the air we breathe: It's invisible. It's ever-present. Without it, you would die in minutes. And it has an epic story to tell. In Caesar's...

"Why does a baking soda and vinegar volcano erupt? That's what happens when you mix and an acid and a base. But just what are acids and bases? What makes them so different? Learn the answers to these questions and more. It's key chemistry curriculum made approachable for all!"-- Provided by publisher.

A unique approach to the history of science using do-it-yourself experiments along with brief historical profiles to demonstrate how the ancient alchemists stumbled upon the science of chemistry. Be the alchemist! Explore the legend of alchemy with the science of chemistry. Enjoy over twenty hands-on demonstrations of alchemical reactions. In this exploration of the ancient art of alchemy, three veteran chemists show that the alchemists' quest involved...

Build on your understanding of aromatics by investigating a very useful class of reactions: electrophilic aromatic substitution. What's the general mechanism by which these reactions occur? What are some of the many modifications chemists can make to benzene? What role did this reaction play in the synthesis of one of the most infamous organic compounds of all time, DDT?

In the 1940s, scientists worked out techniques for speeding up the radioactivity of uranium isotopes by means of a fission chain reaction. See this process modeled with an array of mousetraps, demonstrating how the reaction can be controlled in a reactor or unleashed catastrophically in a bomb.

So far, you have focused on acids that donate a single hydrogen ion in an acid-base reaction. Now turn to polyprotic acids - those that donate more than one proton per molecule. Investigate the complex ionization processes that ensue, and see how they play a role in regulating blood pH.

Professor Davis introduces you to ribose, the central component of both RNA and DNA. Starting from individual molecules and motifs, you'll progressively work your way up toward a full model for the structure of the sub-units involved in our genetic code. This lecture is proof of organic chemistry's powerful role in establishing who you are.

Continue exploring oxygen's role in organic chemistry. Here, Professor Davis introduces you to the properties and reactivity of two simple carbonyl compounds: aldehydes and ketones. What do we know about these oxygen-containing compounds and their chemistry? And what's their curious connection with how you feel after a night of heavy drinking?

You've learned how to depict molecules as they exist at a single point in time. How about as time passes? The answer: much like a cartoonist. Here, learn about this scientific art form, including writing reaction schemes, expanding them into elementary steps, using curved arrows to chart molecular progress, and more.

Chemistry is the study of matter and energy at the scale of atoms and molecules. Covering a year's worth of introductory general chemistry at the college level, plus intriguing topics that are rarely discussed in the classroom, this visually engaging and comprehensive course requires nothing more advanced than high-school math and is suitable for any science background.
