You can just integrate it up I believe. The derivatives in this instance are actually partial derivates if I am not mistaken (the evidence is that Cv is the heat capacity at constant V...which implies that the second term is the change due to volume at constant T). So the total change in S is...

I disagree here. One of the primary tasks of the LHC is to show clear *experimental* evidence that protons do in fact have a definite substructure. The math might tell you that its there, but there is no guarantee that the problem is not with the math (especially since our math does have holes...

Until the LHC or something experimentally demonstrates that quarks exist I am not necessarily sure that they exist much less that they have or don't have substructure. It could BE that the fundamental particles are simply the things that don't show evidence of decay such as a proton or an...

The concept of a dimensionless "point" particle comes from classical physics. That's all I really know for sure. So far there is no experimental evidence of a dimensionless subatomic particle within the nucleus. So the question more or less becomes is SR an approximation? or is it exact, and is...

Make sure there are 4 bonds attached to each carbon. If there aren't 4 bonds attached to a carbon then "add hydrogens" to that carbon until it has 4 bonds.

Correct :wink:

If we know atoms to be what they are, then we certainly know that they are NOT point particles. Atoms have a 3D shape or volume, they can translate, rotate, and vibrate etc. We also know that these atoms are not the ultimate "smallest" particle of matter as they are built up out of even smaller...

The chemical formula you have provided is correct for the number of C's, N's, and O's, but the number of H's is wrong (it is not 21). I don't want to give the name directly because this smells like a homework question...but I can confirm if you have the right formula when you get there.

What are you asking for? The name of the structure?

OOoh...demoted to GD! Errr...math is beautiful, but the process of learning it is pretty ugly (I say the same thing about physics).

Even jokes aren't safe on PF I suppose... Well then, just trust me, chemistry is a fascinating subject if you get a chance to give it a real look at some point. A biologist armed with physics and chemistry would have the tools to make many exciting discoveries as we are going through a...

That description sort of reminds me of a community college that I went to for a brief period of time. Fortunately, I didn't attend a chemistry course there.

If you are solving the wave function by hand that is likely the case for most of us. This approach isn't needed for chemistry anyways, most energy level diagrams for complex molecules or atoms can be generated directly from spectroscopic data and using normalized wave functions together with...

This question can easily be run around in circles depending on how "sound" is defined, but in general you can say that a falling tree on Earth will produce "sound waves" upon falling even if these waves do not carry to a humans ear for a human to become aware that they were made. Note that this...

Here with my folks and sisters with husbands and my sisters newborns. We are trying to decide on a movie to watch at the moment. The men are trying to compromise with Journey to the Center of the Earth or Leatherheads while the woman are hard lining with the Dutchess (which I will NOT watch...
