Thanks

Can somebody please give me a very introductory list of the Zerkmelo-Frankel Axioms? Nothing really technical, just basically what each one means. Thanks!

So does the entropy arise from the fact that not all of the water molecules are traveling at the same speed and some of them may have the energy necessary to evaporate?

I just realized that is not right. What I wanted to say is, how could I make something "falling up" the stairs spontaneous simply by increasing the entropy contribbution to the gibbs free energy change enough?

I guess what I am trying to ask is, is there a way to describe entropy in terms of Newtons laws of motion? For example, if there was some way for me to keep track of all of the equations of motion for every particle in a process, what would entropy represent in them? I guess I know what the...

Why though? I know that that would happen because the second law is one of those "it would be weird if it wasnt that way." My issue, I think, is how does the organization of the energy in a system drive the system against what it energetically wants to do. For example, how does an endothermic...

I am a general chemistry student and I find thermodynamics fascinating. However, I have a hard time visualizing entropy. Can somebody please explain how an increase in entropy can make a process that is endothermic spontaneous? The typical demonstration of entropy that I have seen is on in...

I actually tried this today, except I also applied approximately a 6V potential to it. I got oxidation of the copper wire I was using and a gas. I am not sure what the gas was. At first I thought it was H2 gas from the water being electrolyzed (which I was trying to do), but there was not...

In the Bohr model of the atom, the electron can be pictured as if you were doing a particle in the box calculation where the circumference of the orbit is analogous to the box length. In it, the electron is flying around the nucleus in a semi classical way. However, in the more general case...

The best way to think about it is to realize that our classical perceptions of hings like "angular momentum" do not translate particularly well into the language of quantum mechanics. Even if you do think of an electron as actually "spinning," it is very unusual because the way the math works...

This presents one of the unfortunate conventions used in quantum mechanics. We still use classical words such as "energy" and "angular momentum," to describe non-classical phenomena. Spin first came up a while after the Stern-Gerlach experiment. In this experiment, silver atoms were fired...

Hmm thanks! You seem to be correct according to this article I found (I am not sure you will be able to see it without a subscription)...

For carbon you can use this as a general rule. You can also use it for Nitrogen if you consider its unshared pair a bond.

Step 1: Count the number of bonding regions on the atom in question plus the number of unshared pairs of electrons. Step 2: Beginning with the s orbital and working your way up, keep adding orbitals to the hybridization until the superscripts add to the number of bonding regions. Ex. for...
