Quantum Chromodynamics (QCD)
Electromagnetic force down, three more forces to go! Which one is next? Why it's the strong nuclear force, famous for keeping atomic nuclei together. What kind of particles will be involved in this quantum field theory? Let's find out.

Covalent Bond Energy and Length
We've already learned about different types of chemical bonds, including covalent bonds. But now that we know about enthalpy, and orbitals, and some other concepts, let's revisit the covalent bond and dig a little deeper.

Practice Problem: Analyzing Acid-Base Equilibria
Acids! Bases! Conjugate acids! Conjugate bases! We definitely have to be able to label such things, and we should also know how to state which direction in an acid-base equilibrium is preferred. To do this we should know how to tell...
