[Educator] Bond enthalpies can be used to estimate the standard change in enthalpy for a chemical reaction. Let’s use bond enthalpies to estimate the enthalpy of combustion of ethanol. Looking at our balanced equation, we have one mole of ethanol reacti…

This here is a picture of the ground finch of the Galapagos Islands, and one of its primary sources of food is seeds that it finds on the ground. If we go back to 1976, we can look at the distribution of beak depths, and these beak depths I would assume a…

This is the world’s largest 3D metal printer. It was built by Relativity Space, a startup that aims to print an entire rocket, including fuel tanks and rocket engines, in just 60 days. I’m like looking inside a 3D printed rocket that is actually gonna go …

Let’s imagine a reaction that is in equilibrium: A plus B can react to form C plus D, or you could go the other way around. C plus D could react to form A plus B. We assume that they’ve all been hanging around long enough for this to be in equilibrium, so…
