interesting, that's great that you know that much! That's at least more helpful. It would still be interesting to see why this happens.

I still have all my hair, but It's been close sometimes. Haha. found a bottle of oxygen and it worked great, it went right up. I was thinking of using hydrogen peroxide and maganese oxide (catalyst) to make Water and Oxygen in the flask and boil that through the coil...wonder if that'd be...

Maybe this is more of a chemisty question but I have found that stainless steel is not magnetic. I can only reason that this would be if the Fe (iron) inside the steel is actually bonded with the other components of steel thus making the 3d spins useless to become aligned. i did a search and...

Sorry I have not replied lately, I have been busy getting ready for the school year. Rocketboy- I'm merely trying to show my kids the idea that "steam" is not that cloud they see when they breathe on a cold morning or the cloud that comes outta the shower. It's a demonstrationg to ahve them...

I searched for this and get conflicting results. I have setup a demonstration that has a erlymeyer flask with a one hole stopped and water on top of a heating mantle. I then have a copper tube comming out of the hole in the stopper going into about 5-1"diameter coils and then finally comming...

can anyone give me some good sites for spectral lines and understand how and why spectra occur. Possibly only using the bohr atom. I am a chemistry teacher in maryland, and I'm trying to find some good places so my students could do a search or look at some things online. any ideas...

Gotcha, So you're saying that <r> is Bohr's Radius, but doing a square of the Radial * Spherical WAvefunctions would lend a possiblity of finding the electron outside of <r> but never at the nucleus. Am I reading this correctly? Peter

WE also worry about shearing forces. Eg Depleted uranium is agreat for shells because is shows a phenominae called Adiabatic Shearing force.

I searched the forums to find my answer and didn't find anything within the first couple searches. Here's my question: Bohr developed his model of the hydrogen atom. Then Quantum mechnics came along. Does Bohr's model of Hydrogen work for itself? I always thought even though wave...

So what about more than one mass? So would the reduced mass formula really be 1/u=1/m1+1/m2+1/m3+...

I forget how these two relate both conceptually and mathematically...any help?

Now your question would lend me to ask, how many nanotubes/pumps would you need? Then i would say, what are these nanotubes and pumps made out of? Organic molecules CAN abosorb in visible, but also absorb in UV so think about your UV exporsure too, there things will be in the blaring sun of...

I know i have seen a phase diagram for Hydrogen. And according to the Thermodynamics Hydrogen cannot exsist as metal at 1 bar. I'll see if I can find it in my texts and journals and scan it in.

Mike has an easy way to do it, however, it would be better if you just used the Henderson-Hasselbach equation. You could easily pull all your info from there.

Also, if you want to talk about why certain things do absorb and others don't (thus transparent) we would need to go into some quantum mechanics and look at something like glass as a SHO.
