  1. I'm not sure why you're using the word distills. It doesn't really have any meaning in this context. Distillation is a means of separating liquids through differences in their vapor pressures. *Wikipedia* Are you trying to ask if rain forms from mist? Like mist is water... Like sophist said mist is just suspended water droplets that form around nuclei. Much smaller when they're close to the ground as fog. Or in clounds when they get heavy enough they fall to the ground as rain, or snow...
  2. There isn't a set definition of consciousness, so trying to quantify it is nearly impossible. How can you quantify something you can't define?
  3. I would take it without any hesitation whatsoever. (as long as I'm sure it'd work that is.) And hey if you get sick of live at some point, there's always suicide. It'd be nice to be able to have time to get all that you'd want done done.
  4. Of course it does you just need to add a little sprinkle of fairy dust. And connect it to your standard improbability drive and voila!
  5. Okay here's a recent one of me. Just a little scratched up. I had a rough night the night before. heh
  6. Well no I don't have a floppy drive. It actually took me about a year to realise this, so you can imagine how little use it would have given me.
  7. We use PHYSICAL CHEMISTRY A MOLECULAR APPROACH by MCQUARRIE & SIMON, it pretty much covers it all for any physical chemistry course be it thermodynamics or quantum physics. It is a bit heavy though.
  8. Lol there is plenty of carbon Silly. In Organic Chemistry at every point where two black lines meet there is a carbon atom, plus if there is a line with no indicated atom on the end there is a carbon there. So if you count there are 12 carbon atoms total. On a side note once all the chlorine was used up the NaOH would start reacting with the sucrose to produce a Sodium sucrate salts, but there is already a post on that so I wont go into it.
  9. Actually I think it would work. Though you'd get salt water with sucrose in it. If you put it in solution, first the sodium will react with the H20 (assuming a large excess of water) to give you NaOH (evolving hydrogen which would ignite instantly) which would react to give you sucrose plus NaCl. So you'd get salty sweet water.
  10. (Image taken from pubChem Project) As you can see sucralose is a modified form of sucrose with Cl in place of 3 hydroxyl groups. This prevents it from being metabolised. Also it can no longer be considered a suger, as was pointed out by Moleke, since it no longer contains JUST C,O, and H.
  11. Now most cause rifles use a coil of wire and send a projectile through it. But they seriously lack efficiency and power. I wonder if there is a way in wich you could create the same effect from a Halbach arrays by winding a wire. Seems you could get a much more efficient gauss rifle out of that. Though you'd have to reverse the polarities of the magnets to get the field to poin the projectile in the right direction.
  12. That is weird, is this question from a text? Or from your proff? Have you asked him about that?
  13. Chimeras have been done before. http://news.nationalgeographic.com/news/2005/01/0125_050125_chimeras.html http://en.wikipedia.org/wiki/Chimera_(animal)
  14. Just to answer my own question I found a couple of good books. At the Bench: A Laboratory Navigator, Updated Edition From CSHL press is a good place to start Short Protocols in Molecular Biology is also supposed to be good though I haven't had a look at it yet. There is also a three volume set called "Molecular Cloning: A laboratory Manule" which is also good, but way to expensive for me right now. Maybe some day when I'm done grad school I'll buy them as a present for myself. Yes you should definately finely tune your own protocols, but having a book handy to quicly reference something new from can be invaluble. Plus books just feel so much nicer.

    to learn

    A good book for people new too these protocols is At the Bench: A Laboratory Navigator, Updated Edition From Cold Springs Harbour Laboratory Press. I'd suggest buying it directly from their website as you will be sure to get the most updated version. It's very good for the fields that you mentioned particularly with Molecular biology techniques, cell cultures, Genes and such. You could also find everything on the internet, but sometimes there's just nothing like a nice solid book to flip through.
  16. Hmmm maybe you're right the benzene might be too deactivated. I'll look into it later. I was more confused why he'd want to hydrogenate it in the first place. *edit* Right you could hydrogenate the benzene to cyclohexane but it would require high pressure and temperate which wouldn't be required for hydrogenation of the alkene. Still hydrogenation isn't necessary in the first place. Do a clemmensen reduction instead.
  17. I agree the proposed answer is wrong. Hydrogenation just doesn't make any sense at all, I can't even begin to understand why they'd recomend hydrogenation, you'd just endup with substituted hexane. I think maybe he ment to say that halogens don't really activate/deactivate very much? They're considered ortho/para directing and weak deactivators. My book here has an example of a nitration on chlorobenzene and there is only a 1% meta yeild. I think that my previously posted solution would work well. *edit* Yes it will work (though the halogenation will proceed far slower then with benzene); it will still produce the product and almost entirely the meta as well.
  18. I dissagree. Your method would produce no desired product at all. First of all you'd get about 1% meta yeild, (Organic chemistry 3rd edition L.G. WADE). Secondly you can't use propyl chloride to add a proply group; the carbocation would rearrange to the most substituted position and you would get the addition of an isoproply group instead. You must instead us an propanoyl chloride group, then follow it with a clemmensen reduction (Zn(Hg) + Weak HCl). I believe this is the proper procedure. First use propanoyl chloride with AlCl3 and H20 Secondly do your chorination with Cl2 and AlCl3 Third clemmensen reduction with Zn(Hg) and aq HCl
  19. Yeah didn't notice, I guess it'd kinda like saying works all the time 60% of the time. Yeah noticed that too hence why I used the word produce. Maybe that's why he didn't get an web hits for his search.
