Arrhenius acids/bases
Arrhenius acids/bases are briefly mentioned throughout chapter 12. Is this something that we should familiarize ourselves with?

Re: Do I use an ICE box?
For this question, do we have to divide by the coefficient of Br, 2?

Re: Finding The Direction of Reaction
I think the easiest way to finding the direction of a reaction is by using an ICE table.

Atomic Radius
Can someone please explain why the radius of the atom of a lithium that undergoes a transition from the 2s orbital to the 2p orbital increases? This question was taken from 2.33(d) on the homework. I assumed that since Lithium is moving towards the p-block the atomic radius would decrease based on t...

Post Module #17 [ENDORSED]
I'm stuck on this conceptual question from the photoelectric effect post-assessment:
If long wavelength light is not ejecting electrons from a metal surface will increasing the intensity of the light result in electrons being ejected? Justify your answer.
