  1. the acetic acid isnt being decarboxylated, but the bicarbonate is
  2. the reaction occurs via a decarboxylation mechanism
  3. well, it should be noted that the volume of a gas depends on a number of factors.
  4. "Oxidation doesn't require non-covalent species. If something is 'oxidized' it just means that its oxidation state has increased. So if the oxidation state of oxygen in a compound is -2, but it then it reacts and the oxidation state goes to -1, the oxygen has been oxidized even if it's not an ionic compound. You do not need an ionic species to have oxidation or reduction going on." see, this is a matter of personal preference. i like to say that chlorine is trivalent in chlorine trifluoride and there is a delta+ on the chlorine and delta- on each fluorine. "Also, your formula for FNO3 is incorrect. It should be written as NO3F, or NO2OF according to Linus Pauling. (You can see his research on the compound here." actually, my formula is corect. and the compound has a number of names, including: fluorine nitrate, nitryl hypofluorite, nitroxy fluoride. it's prepared by the action of fluorine on nitric acid. "Indeed there is a compound NO3F, but not a compound MnO4F. The highest oxidation state in which manganese exists is +7 and that is in MnO4(-), Mn2O7 and MnO3F." in FNO3 there's an F-O bond, last i checked. same thing in permanganyl fluoride/fluorine permanganate/permanganyl hypofluorite, which, in fact, exists
  5. well, define "oxidize." i consider chlorine trifluoride, for example, to be covalent, so chlorine really isn't "oxidized" per se. plus there exist compounds such as FMnO4 and FNO3, which don't exist as F+ and MnO4- or NO3-; they're more covalent, so fluorine isn't "oxidized" per se, nor is it "reduced."
  6. that blows. but why is this in the politics forum?
  7. "That is a statement about the people who compiled these lists - not about asian physicists." i hope you realize that you are implying that the nobel prizes of old are all of sham. have you any comments on any other part of my most recent post? btw douglas, i'm better at basketball than the 5 year old black kid across the street. i think you should consider saying "some" or "most" instead of making the generalization of "all"
  8. "Largely because in the US european history is taught in public school, whereas Asian history is generally ignored." last i checked, us and global history classes didn't teach anything about physicists, save newton "Kinoshita, Maskawa, Wu, Yukawa, Ting, Koshiba, Tomonaga, Yang, Chandrasekhar, Bose, Giri, Raman ...." now if we search for "famous physicists," our first result is the following: http://www.phy.hr/~dpaar/fizicari/ yukawa is the only one mentioned. in fact, he was the only guy mentioned who wasn't white, so fancy that. according to the second hit, http://cnr2.kent.edu/~manley/physicists.html there are 4 indian, 4 japanese and 3 chinese and one pakistani nobel laureate in physics, including ___-born americans this isn't to say that asians are inferior. i love my asian friends. i'm currently seeing someone who is first generation indian and possibly the most brilliant person i've ever met. i have a great number of close friends who are of asian descent. and i do recognize the fact that asians have contributed a whole lot to physics. however, i would not say that white people are inferior because they don't have the "work ethic" that is allegedly part of asian culture. visit china. you'll find plenty of lazy, unintelligent people, just as you'll find anywhere else. if you were to take the smartest europeans and ship them off to, say, pakistan, they would be considered far more studious, just as asians often are in the us. if you take a sample of the elite of one culture and compare them to the average of another, you won't obtain accurate results on the "work ethic" of one culture relative to another
  9. since when were caucasians lazy? since when were asians more studious than others? name a famous physicist. chances are he/she's european. asians you see may be more studious becuase they're the parents of immigrants who worked their asses off to go to college, get a job and leave their home land
  10. hehe, i'd say it would be H3O+ and HSO4-
  11. once again, PbCO3 would precipitate in the blood and the girl would die
  12. PbCO3 would precipitate in the blood and the girl would die
  13. genetic differences based on race is really taboo because it proves that all men actually aren't created equal. we see a higher risk for sickle-cell anemia in africans and those of african decent because those with sickle-cell anemia didn't get malaria. in the us, asians do better on the sats because the smartest asians came from various asian countries. it's not a wonder why the best marathoners come from kenya- kenyans throughout history have had to run all their lives to stay alive. so maybe black people do play basketball better. and maybe white men can't jump.
  14. see, i never understood why people used HF to clean things when nitric would work so much easier. HF is bloody toxic as all hell, while nitric is not nearly as dangerous
  15. interestingly, ruby is aluminum oxide with slight traces of chromium salts and sapphire is aluminum oxide.
  16. mol III doesn't have a carbocation. it does have a protonated hydroxyl group, which is an excellent leaving group. the hydroxyl itself is a terrible leaving group, but the OH2+ can easily come off as water. the fact that it's on a primary carbon makes it more susceptible to nucleophilic attack than elimination. by carbon i meant the oxygen:\ the fact that the oxygen is SP^2 helps because the O-H bond is weaker
  17. you're right with the answer, but a few corrections: "carbocations" it would actually yield a carbanion, which is even less favorable "Molecule III is the strongest acid because its postively charged Oxygen is highly unfavorable, and if it loses an H it would become highly stable" actually, molecule III is reasonably stable, but certainly acidic. this sort of thing is what you get when you put a pure acid in an alcohol. in such conditions it's highly susceptible to nucleophilic attack and elimination reactions "OH group can lose an H and become resonance stabilized," interestingly, it's actually resonance stabilized already. and the fact that the carbon is SP^2 helps
  18. i did not mention any solvent in particular. i should have mentioned use of, say, methanol. while enantiomers may have the same physical and chemical properties, diastereometric salt complexes from each enantiomer of a chemical do not have the same physical and chemical properties. after forming these salts, fractional crystallization can occur
  19. hot hot did you heat the boron oxide to get it to thermite?
  20. but then the octet rule wouldn't be satisfied. N-O nitrogen would have 2 lone pairs and the bond, so effectively 6 electrons. oxygen would have effectively 7 electrons.
  21. take the racemate, react to form a salt, then use the different solubilities of each isomer to fractionally crystallize out one isomer
  22. methyl 2-methylpropeneoate is the methyl ester of 2-methylpropenoic acid. basically it's H3COOCC(CH3)=CH2 to form the methyl ester of 2-methylpropenoic acid must be somewhat tricky, as with fischer esterification, there is competition with the hydration reaction of the alkene. with nucleophilic substitution, there is competition with the addition reaction to the alkene as well.
