Thanks for the reply, but could you go a little bit into how it can be used to answer my question? It doesn't seem to, from what I can tell

Oh wow, I can't believe I did that. Thank you. But still, Keq seems to be going to a smaller value, while ΔG is becoming more negative, which doesn't make sense.

I posted this earlier, but I just realized it might have been in the wrong section. Sorry Okay, so consider you have system in which ΔG<0 and ΔS>0. Using Gibbs free energy (ΔG=ΔH-TΔS), you'll know that it will always be negative. As the temperature increases, it will actually become more and...

Homework Statement A car whose wheels are of radius r feet is driven at a speed v. A pebble is thrown from one of the wheels. A. Neglecting air resistance, find the max height above the roadway which the pebble can reach as a function of r, g, and v. B. For very small values of v, what does...

I'm taking an AP class.. This is just part of the summer work that I have to do.. I haven't even met my teacher yet, I'm sure he'll explain it though.

But still, how does silicon ionize? the question is asking me to ionize silicon and lead.. both have 4 electrons in their valence shell

That is the exact quote, word for word. I don't really know how to answer it though.. And why do you say that?

Homework Statement When does an atom become a cation and an anion?Homework Equations The Attempt at a Solution Cations have a positive charge because they lose electrons, and anions have a negative charge because they gain ions. The atom would always want to do what requires the least energy...

This question is pretty straightforward, but I just can't seem to find the answer.. What is the reason that electrons only exist in shells and never between them? A hint that was given to me was to "think about quantum energy". I was thinking because if they wouldn't exist in shells, then...
