    What are the Zermelo-Fraenkel Axioms and their meanings?

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

    Entropy and Endothermic Processes

    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?

    Entropy and Endothermic Processes

    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?

    Entropy and Endothermic Processes

    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...

    Entropy and Endothermic Processes

    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...

    Entropy and Endothermic Processes

    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...

    What is the chemical reaction with copper?

    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...

    How Do Electrons Exhibit Standing Wave Behavior in Atomic Orbits?

    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...

    Spin and intrinsic angular momentum

    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...

    Spin and intrinsic angular momentum

    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...

    How is the hybridization type determined in relation to VSEPR theory?

    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)...

    How is the hybridization type determined in relation to VSEPR theory?

    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.

    How is the hybridization type determined in relation to VSEPR theory?

    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...
