  1. hydrazine is a reducing agent- it's a fuel. consider the wolff-kishner
  2. the reaction is just an application of acidity and basicity. H+ is more acidic than Na+ and F- is more basic than Cl-, so those ions react more. the weaker acid, Na+ and weaker base, Cl- stay in solution completely. Much H+ and F- stays in solution, but some covalency is observed and we see some HF
  3. if you're going to write about kids playing with H2S you may as well make it HCN. despite it being less detectable, it works in the same way as and, though it is less toxic than H2S, is at least more well known by parents who can shield their kids from such writings
  4. moronic acid actually exists, so you may want to use that. yt, hydrogen sulfide really isn't something to joke about. it's a really good way to die in 10 minutes and not even notice the gas is still around when it kills the nerves in your nose.
  5. how about antiaromaticity, pericyclic reactions or bond delocalization? your question is a bit unclear to me. try one of those- they're cool.
  6. i fail to see how abstinence is the best policy. are adults not just as susceptible to diseases and unwanted pregnancies as adolescents?
  7. it's really too bad that this sort of thing happens. like it or not, sexuality can be a huge part of life and can be so in a healthy way. unfortunately, many kids don't grow up to appreciate the gift that is to be found in their sexual potential and they miss out on one of life's greatest pleasures. when they finally do discover it, many do not know how to go about doing it. also, many people hate themselves for their fetishes because they don't know they're acceptable, if not common. this sort of thing should also be mentioned in classes for the mental benefit of students. it's ridiculous. do we have a bunch of frigid legislators or what?
  8. this isn't chem. mods, could you move this?
  9. the peon, in response to your response to my first post: i did read your entire post, including the part where you said "Of course im generalizing, cause a model could be a nerd, etc. Guess this is an "im bored" poll type thing." i, at that moment, was just annoyed by the stereotype and was questioning its validity even though in doing so i digressed from the original topic. my apologies.
  10. since when were models good in bed? since when were nerds not? you'd be surprised by the sex drive many nerds have and how frigid many models are. looks certainly do not correlate with bedroom skill.
  11. that's exactly what i said, except i added in the part about heat making acids more corrosive
  12. well, technically yes, but in reality, no. the limestone would react to neutralize the acid, making it effectively non-corrosive. however, this reaction does yield heat, which would make any remaining acid more corrosive. but in reality, no. and why the graham condenser?
  13. you get the nucleophilic addition product- the carbonyl is reduced to an alcohol and the formerly carbonyl carbon has a phenyl group attached to it.
  14. your best bet is to form the hydrochloride salt of pyridine and go from there. make sure the HCl you add is dilute enough so that it does not react with the ethanol to form ethyl chloride. when you're done, convert the PyHCl to the freebase with excess hydroxide.
  15. i think it's a good deal if only for the mangoes
  16. the reaction is an anti addition. the electrons from the pi bond of the ethene attack one atom of bromine in the diatomic molecule, causing the electrons from the sigma bond between Br and Br to go to the Br atom that was not attacked by the pi bond. simultaneously, the Br attacked by the pi bond puts a lone pair of electrons on the other carbon, making it bonded to two carbon atoms and positively charged. finally, the bromide anion performs an sN2 reaction, attacking one carbon, inverting the stereochemistry and causing the electrons from the C-Br+ bond to go to the bromine atom. Step 1: Br-Br H2C=CH2 Step 2: Br- H2C(Br+)CH2 Step 3: H2BrC-CBrH2
  17. eh, woelen, i have to disagree. ecoli said: "one with concentration X of H+ ions and one with concentration X of OH- ions will neutralize each other to form pH 7." you said: "No, unfortunately you are not right. Things are quite a lot more complicated. What you are stating here only is valid for a strong acid and a strong base, which both are fully ionized in water (e.g. HCl and NaOH)." the key words are boldfaced. if you have, say, 1.1 moles of a hydroxide, but only 1 mole ionizes, the mole of hydroxide anions will neutralize 1 mole of hydronium cations. of course, there will be an equilibrium and more hydroxide will ionize as it reacts with the hydronium, but that varies from case to case and a correction can be made stating that we have, say, slightly less hydroxide in this example. but back to the point, ecoli was talking about available ions, and he is right- if you have, say, 80 moles of a monoprotic acid and that yields only 1 mole of hydronium cations, it will neutralize the mole of hydroxide anions from a mole of, say, cesium hydroxide.
  18. what bothers me is the fact that many people are hearing the headline "us gives port security contract to arab nation" and making an opinion, generally that it's a bad thing. based on this information alone, one cannot make an informed decision as to whether they believe the transaction was good or bad.
  19. aha! here's something that genuinely pisses me off because teachers and many books are too stupid to tell the difference. the "reactivity" series you speak of is actually called an "activity" series. the activity series is based on electromotive potentials required to reduce cations of a metal to the ground state. and no, cesium (or francium if your teacher/book gave the impression that it actually exists in any significant quantity in the same place at a given time) is not the most active metal. that would actually be lithium. reactivity is based on rates of reaction- ie, how fast X will react with Y relative to Z reacting with Y when all reactants are in the same conditions in both reactions.
  20. you could make the isopropyl ester of methylphosphorofluoridic acid:rolleyes: that's pretty exotic. and deadly. you could also make the glyceryl ester of nitric acid. that (nitroglycerin) would be explosive
  21. wow. that explains a whole lot. the gas evolved looked very similar to the ClO2/Cl2 mixture on your link. luckily i did the experiment at night so the minimal available light didn't detonate the ClO2. the solid left behind was pretty yellow and slightly orange.
  22. uncle ben, you made chlorine gas. bleach is 2NaOCl+H2O at equilibrium with 2NaOH and Cl2. when you react bleach with an acid, the equilibrium is pushed to the right as the NaOH reacts with the acid forming a sodium salt and water. as a result, the free chlorine gas is liberated
  23. heh, last i checked HSbF6 was 10^18 times more acidic than H2SO4
