Chemistry raised to the power of AWESOME! That’s what Hank is talking about today with Electrochemistry. Contained within, Hank discusses electrochemical reactions, half reactions, how batteries work, galvanic cells, voltage, standard reduction potential, cell potential, electrolysis, and electro plating and the things that go into making it possible for you to watch this episode of Crash Course Chemistry!
The UN has announced it’s undertaking the effort to protect the planet from killer asteroids. Trace explains what their plan is if a giant space rock sets it’s sights on Earth.
