No, I need to have the groups attached to the silicon (except the PEG... yes you are right, I did mean polyethylene glycol) to undergo an elimination reaction with a hydroxyl group. This would attach the PEG onto another molecule via the silicon. I don't think the methyl groups would do this...

Is Silicon chemistry very similar to Carbon chemistry? Being in the same column with the same number of valence electrons, I assume it would be? Would I be able to use the same mechanisms I learned in my Organic Chemistry class? I ask because I'm trying to synthesize PEG-trimethoxysilane...

Homework Statement Write down the full Hamiltonian for a hydrogen atom in an external field. Next, calculate the energy changes deltaE (not absolute E) of the three orbitals Y01, Y11, and Y-11 induced by the applied magnetic field Bz. Interpret your results with respect to your knowledge of...

I guess that makes sense. So you are saying that in the current context, then both locality and realism cannot be true. If non-local forces were at work, this would be described by hidden variables, am I correct? Man this stuff is so counter-intuitive for me... so hard to understand.

Proof of state "collapse? Maybe I don't even have the terminology correct for this... I'm a quantum physics noob :) My question is this: take the EPR experiment for example. What I've heard is that each electron in the pair is in an indefinite state of spin (either + or - with respect to a...

Why do you keep saying that dU = 0 if dT is zero? Please refer to my equation: dU = TdS - PdV If either T and dS are nonzero, or P and dV are nonzero, then there is a change in internal energy (dU =/= 0). T is always going to be nonzero (especially in this case). dS will be greater...

PV work (expansion of a piston) takes from the internal energy of a system.

I disagree. dU = TdS - PdV, so a change in volume definitely accounts for a change in internal energy.

Right... I used a macroscopic set of objects as an example to try and explain how I don't understand. I think he was just going along with my metaphor that the cards are basically an electron singlet.

I don't understand this. How can his spin "become" something? I mean, think of this: a friend of yours has two playing cards, a queen and a king. The fact that one is a king and the other is a queen is a reality. The type of card is an intrinsic property. So now, the cards are turned...
