based on homework problem 6.1, every substance had london forces. Is this true for essentially any substance we'd encounter?

Yes all substances have London forces, because all molecules have the possibility of having dipole moments which I think are the same thing as London dispersion forces.

Yes, every atom can exhibit london dispersion forces because it is due to the essentially random movement of electrons in an atom resulting in the formation of a temporary dipole.

Yes, London forces are "universal" because they act between all molecules. They are the only interactions between non-polar molecules. The strength of the London forces typically increases as molar mass increases.

Is there a specific way we can tell when london forces are acting in molecules?

Yup, all molecules have london forces I believe due to the way electrons orbit the atom.

All atoms have fluctuating electron distributions that will be distorted in some way, which will create an induced dipole. These forces are more prevalent in atoms with more electrons compared to atoms with less electrons, because there are more electrons that can be polarized.
