Physical Science : Going Green With Renewable Energy

Hi, I’m Steve Jones, and I’m going to tell you how to go green with renewable energy. Now, we know that at the moment we use these fossil fuels; oil, gas, coal, and nuclear fuel. We use them all to generate electricity for our houses, we use oil in our cars, petrol comes from oil. […]

Energy Diagrams, Catalysts, and Reaction Mechanisms

professor Dave here, let’s learn about reaction mechanisms we’ve learned a lot about chemical reactions but what is necessary for a reaction to occur on the molecular level? collision theory states that molecules involved in a reaction whether in the liquid or gas phase have to collide in a particular orientation and with an amount […]

Are Energy Drinks Really that Bad?

– Energy drinks! (upbeat music) We hear all the time that they’re really bad for us, especially for teens, but we all drink them anyway. So are energy drinks really that bad? First, let’s rewind back to 1997, the year Titanic came out in theaters, and I looked like this. It’s also when RedBull became […]

Orbitals, the Basics: Atomic Orbital Tutorial β€” probability, shapes, energy; Crash Chemistry Academy

This tutorial is about orbitals. We’re going to look at what orbitals are, what they represent, how electrons go in orbitals, the order electrons go in orbitals, and the shapes of orbitals. So we know that atoms are made out of electrons, protons, and neutrons. Electrons are very important. The arrangement of electrons dictates how […]
