23. Polar & Non-Polar Molecules: Crash Course Chemistry #23
No release date yet
Molecules come in infinite varieties, so in order to help the complicated chemical world make a little more sense, we classify and categorize them. One of the most important of those classifications is whether a molecule is polar or non-polar, which describes a kind of symmetry.
22. Atomic Hook-Ups - Types of Chemical Bonds: Crash Course Chemistry #22
No release date yet
Atoms are a lot like us - we call their relationships "bonds," and there are many different types. Each kind of atomic relationship requires a different type of energy, but they all do best when they settle into the lowest stress situation possible.
21. Lab Techniques & Safety: Crash Course Chemistry #21

Hank takes a break from the desk to bring you to the lab in order to demonstrate some important points about the practical side of chemistry - experimentation in the laboratory. You'll learn what to wear in the lab, how to dispose of chemicals safely, and how to avoid the most common accidents.
20. Entropy: Embrace the Chaos! Crash Course Chemistry #20
No release date yet
Life is chaos and the universe tends toward disorder. But why? If you think about it, there are only a few ways for things to be arranged in an organized manner, but there are nearly infinite other ways for those same things to be arranged.
19. Calorimetry: Crash Course Chemistry #19
No release date yet
Today's episode dives into the HOW of enthalpy. How we calculate it, and how we determine it experimentally...even if our determinations here at Crash Course Chemistry are somewhat shoddy.
18. Enthalpy: Crash Course Chemistry #18
No release date yet
If you are paying attention to this episode you'll learn what the state function is, and how it varies from a path-dependent function; why enthalpy change is different from heat; that bonds are energy and to form and break them they release and absorb heat to and from their environment.
17. Energy & Chemistry: Crash Course Chemistry #17
No release date yet
This week, Hank takes us on a quick tour of how thermodynamics is applied in chemistry using his toy trebuchet as an example because he is a proud nerd.
16. Passing Gases: Effusion, Diffusion, and the Velocity of a Gas - Crash Course Chemistry #16
No release date yet
In this episode, Hank describes what it means when we talk about the velocity of a gas - to understand gas velocity, we have to know what factors effect it, and how.
15. Partial Pressures & Vapor Pressure: Crash Course Chemistry #15
No release date yet
This week we continue to spend quality time with gases, more deeply investigating some principles regarding pressure - including John Dalton's Law of Partial Pressures, vapor pressure - and demonstrating the method for collecting gas over water.
14. Real Gases: Crash Course Chemistry #14
No release date yet
Hank bursts our ideal gas law bubble, er, balloon, and brings us back to reality, explaining how the constants in the gas law aren't all that constant; how the ideal gas law we've spent the past two weeks with has to be corrected for volume because atoms and molecules take up space.
13. Ideal Gas Problems: Crash Course Chemistry #13
No release date yet
We don't live in a perfect world, and neither do gases - it would be great if their particles always fulfilled the assumptions of the ideal gas law, and we could use PV=nRT to get the right answer every time.
12. The Ideal Gas Law: Crash Course Chemistry #12
No release date yet
Gases are everywhere, and this is good news and bad news for chemists. The good news: when they are behaving themselves, it's extremely easy to describe their behavior theoretically, experimentally, and mathematically. The bad news is they almost never behave themselves.
11. How to Speak Chemistrian: Crash Course Chemistry #11
No release date yet
Learning to talk about chemistry can be like learning a foreign language, but Hank is here to help with some straightforward and simple rules to help you learn to speak Chemistrian like a native.
10. Redox Reactions: Crash Course Chemistry #10
No release date yet
All the magic that we know is in the transfer of electrons. Reduction (gaining electrons) and oxidation (the loss of electrons) combine to form Redox chemistry, which contains the majority of chemical reactions.
9. Precipitation Reactions: Crash Course Chemistry #9
No release date yet
A lot of ionic compounds dissolve in water, dissociating into individual ions. But when two ions find each other that form an insoluble compound, they suddenly fall out of solution in what's called a precipitation reaction.
8. Acid-Base Reactions in Solution: Crash Course Chemistry #8
No release date yet
Last week, Hank talked about how stuff mixes together in solutions. Today, and for the next few weeks, he will talk about the actual reactions happening in those solutions - atoms reorganizing themselves to create whole new substances in the processes that make our world the one we know and love.
7. Water & Solutions - for Dirty Laundry: Crash Course Chemistry #7
No release date yet
Dihydrogen monoxide (better known as water) is the key to nearly everything. It falls from the sky, makes up 60% of our bodies, and just about every chemical process related to life takes place with it or in it. Without it, none of the chemical reactions that keep us alive would happen.
6. Stoichiometry - Chemistry for Massive Creatures: Crash Course Chemistry #6

2. Unit Conversion & Significant Figures: Crash Course Chemistry #2
No release date yet
A unit is a frequently arbitrary designation we have given to something to convey a definite magnitude of a physical quantity and every quantity can be expressed in terms of the seven base units that are contained in the international system of units.
1. The Nucleus: Crash Course Chemistry #1
No release date yet
Hank does his best to convince us that chemistry is not torture, but is instead the amazing and beautiful science of stuff. Chemistry can tell us how three tiny particles - the proton, neutron, and electron - come together in trillions of combinations to form ... everything.
