! Moderator Note Please avoid the unrelated discussion on specific physics questions. Such questions are not on topic and from what I can tell, were already addressed in a previous (and now closed) thread.

! Moderator Note Hi GadgetMan989, please note that SFN is a science forum, not a conspiracy theory forum. Try to keep your posts founded in reality and based on evidence.

! Moderator Note arc, The paragraph of insulting, derogatory remarks towards Aemilius are totally unacceptable. If you have nothing constructive to say, please don't bother contributing. Aemilius: the same applies to you. If you cannot make a post without resorting to the rhetoric that anyone that may disagree with you lacks proper education and belongs in an insane asylum, it might be worth questioning whether or not you have a valid point at all.

! Moderator Note Thread closed, as per my previous mod note: http://www.scienceforums.net/topic/85170-choice-of-reference-sequence-and-assembler-for-alignment-of-listeria-monocytogenes-short-read-sequence-data-greatly-influences-rates-of-error-in-snp-a/?p=823452

! Moderator Note Meshari Binomar, This is a discussion forum, not a site for you to copy paste abstracts from papers with no direction for meaningful conversation. Please note that soap boxing is against our forum rules - as is advertising of any form - and as a result, this thread as well as your other thread is now closed.

Seems a bit odd. I wouldn't think it would burn readily. Do I you happen to know if there are significant amounts of any other contaminants in there? Vinegar often has sugar in it, which may explain the burning, though it's supposed to be quite a minor constituent. How are you boiling the water off? I would avoid using temperatures too much in excess of the boiling point.

! Moderator Note GadgetMan989, Please do not simply copy and paste whole articles from elsewhere onto this site. This is plagiarism and not conducive towards discussion. I have deleted the article and closed this thread. You are welcome to reopen it, but do not paste the entire article in the thread and please provide a link to the article should you want people to read it or if you want to quote it.

Irbis/SlavicWolf has been banned due to frequent violations of rule 1, regarding slurs against groups, and a combination of other infractions.

! Moderator Note SFN has a strict no-duplicate-accounts rule. If you had problems logging in, contacting staff should have been your first point of call. Given your history as SlavicWolf, both accounts are hereby banned.

! Moderator Note Alright, closed. You are not permitted to reintroduce this topic again.

! Moderator Note metacognitans, This thread will be closed in T minus your next post if you do not adequately respond with scientific answers and evidence to the questions that have been asked of you. Do not respond to this mod note in the thread.

At a very quick glance, the initial stages appear to be: Edit:

Citation, please. Edit: and preferably in a thread where it is on topic.

I'd recommend, 'Chemistry,' by Blackman or the similarly named text by Zumdahl and Zumdahl, though I don't recall if it covers much in the way of stoichiometry or those sorts of basic calculations. They also don't include any solutions to the review questions, but there are worked examples throughout the chapters.

! Moderator Note Discussion on GMO food is probably best left for one of the many existing threads on the topic.

Then please ask specific questions about it. What exactly do you wish to know?

It would depend on what you get. The ones containing flavoring additives are obviously not pure. What do you need to for?

No. NaCl doesn't dissolve in acetone. And it's not to do with carbonyls, only alkyl halides. It's an SN2 reaction.

What would reflux do to make it work? The Finkelstein reaction doesn't need to be under reflux. You do need anhydrous acetone, though. As I said, akyl halides will undergo halide exchange. See here. The same is unlikely to be true for acid halides or acids. If you performed the reaction in water, the acid halide would hydrolyse. If you performed it in another solvent, the only way I could see it happening is if you used a phase transfer catalyst or some other solvent that exploited differing solubilities. Still, it seems unlikely that it should happen.

Presumably if you were to try it, you would do it in acetone for something like NaI or use a PTC.

Most likely because the resulting carbonyl compound would be very reactive and reform the starting material. Alkyl halides do actually react in the presence of halide salts, as per the Finkelstein reaction.

It has everything to do with pain. Perhaps if you'd read the replies people took the effort to write or some of the abundant information online (you know, beyond outdated snippets from the 80's that vaguely supports something you said), you would understand this. Please go back and actually read this thread without the Dunning-Kruger glasses on before you reply.

My advice to you would be to try not to conflate people giving up on pointless and repetitive conversation for evidence that those people think that you are at all correct. CharonY has given you some excellent information that you might wish to revisit.

Yes.

I think the latter part of your last statement is pretty much correct. One example I can think of is dietary sources of vitamin C. I could get all the vit. C I need by just eating something like a Kakadu plum, which is native to the northern and western parts of Australia. Moving to Asia, I no longer have Kakadu plums, but I can get vitamin C from other fruits, like kiwi fruit.
