for your peroxide, look online, or better yet, go get 3% at a pharmacy and fractionally freeze it. your peroxide should freeze at -11 celsius, while your water will freeze at 0. use 20-40% sulfuric. dont even try to evaporate the solution, as you will die. you will have to be careful with the molarity and volume of your sulfuric and peroxide. if you aren't careful, you will get peroxymonosulfuric acid, which is not to be messed around with because it detonates easily and will rip through your flesh with haste (hence its nickname pirahna bath). do not add your ammonia until after you recover your crystals. to recover your crystals use a solvent. be careful, as isopropanone will yield AP, which is also very unstable. also, be careful when working with carbon chlorides, as you just may end up with phosgene or a similar compound. also, alkanes are no good, as they will explode.

calm down buddy. what you have is a metal powder and a strong oxidizer. that is, most certainly, a flash powder. your metal is probably aluminum or more probably magnesium. your white powder could be a myriad of things, so try some qualitative tests
-
it's probably a flash powder

i take it you mean nitrogen triiodide. you cant do it with tincture. acidify the tincture with sulfuric acid, then add a strong oxidizer (try some conc hydrogen peroxide) and recover the iodine crystals. iodine crystals are really expensive so just try obtaining them with the tincture. as a side note, do not make any more than 2mL of this at a time, lest you die. nitrogen trihalides are incredibly unstable and are usually detonated by a slight air movement.

i think he wasnt looking for a place to buy, but rather his project was to figure out information to make an advertisement for his element

the iq test is a better sign of intelligence than any other test we have including the sat and act

right, helium has 2 electrons. it is the one exception. sodium actually requires one electron to complete its outer shell because its outer shell is an s. thats why you dont see Na-7 anions in solution with liquid anhydrous ammonia. it loses its electron because of our lovely equation: X=((0.31(n+1+or-c))/r)+0.50 n=valance electrons c=formal valance charge on atom. is positive or negative depending on polarity of charge. r=covalent radius
-
i wouldn't be the least surprised
-
yeah, thats exactly what i mean. that's also the second time in the last few hours in which i have made that sort of mistake. i think the permanganate is going to my head
-
i have to agree with luciddreamer on this one. if those are the actual iq averages, there is no denying it.

it would get cold again. the reaction for dissolving ammonium nitrate is endothermic. when it comes out of solution the reaction is exothermic and it gains energy for it to lose again when it is put back into solution
-
ack, i meant lower. sorry about that
-
electronegativity. according to linus pauling: X=((0.31(n+1+or-c))/r)+0.50 n=valance electrons c=formal valance charge on atom. is positive or negative depending on polarity of charge. r=covalent radius
-
right but youre left with ionized hydronium cations running around protonating things. see what i mean?
-
the atomic radius of chlorine is significantly greater than fluorine. thus its effective nuclear charge is greater.
-
well actually, i believe that youd find that the fluoride ion causes many crazy reactions. think of it this way, we have the Na+/K+ pump going on in the axon of nerve cells. so then a bunch of HF comes in. the F- decides to stick to the Na+/K+ and you are left with a bunch of H+ that goes around protonating things
-
actually, HF doesn't dissociate too much because of the strong forces between the hydrogen and fluorine
-
they may. my school is really stupid and we never do anything remotely dangerous. last year, our most "dangerous" chemicals were fuming 14M HCl, minute quantities of 18M sulfuric...we burned some magnesium. thats just about it for "dangerous" chemicals. well, we made some banana oil, which would have enraged bees if there were any in the room but since there weren't, nobody was attacked. at the same time, i know somebody who goes to a school near mine, who supposedly made nitric using the nitrate salt+sulfuric setup. also, a friend of mine made silver acetylide for his final lab last year. so, i bet you could use HF in a lab

last night i had the opportunity to see howard dean speak. i found him to be remarkably reasonable and insightful. he first spoke of the importance of running for office. according to him, most of the people in lower political positions have minimal if any prior experience. he told the story of his cousin, a democrat who was elected to a position in utah, the most conservative state. he won because there was a scandal, but now he has the opportunity to gain back some left support in a very conservative state. also, he mentioned how in alabama (i think it was alabama, or another southern state) a black lesbian woman was elected. now she may be able to influence people to be more tolerant. dean also compared anti-homosexual sentiment in this country to racism experienced before the civil rights movement. back in the day, many caucasians were afraid of swimming in the same pool as a child of african descent for fear of becoming diseased. it turned out that doing so would not really yield a problem. dean explained how the homosexual community is currently experiencing the same rediculous opposition, despite their being the same as everybody else, with the one difference being sexual preference. according to surveys, the importance of various issues among 95% of heterosexuals and homosexuals were ranked the same. speaking of divisive issues, dean explained that the right has chosen to emphasize the issues of "guns, god, gays and abortion" to divide and conquer. dean called for themes from the left to emerge, such as education and economics, to counter these divisive themes. he cited a flaw in kerry's campaign as being the fact that kerry conformed with the republicans and emphasized the same issues as the republicans. what we need, he said, are two separate parties rather than two republican parties. also, while speaking of issues, dean mentioned how the media has become more of an entertainment source than an actual news source. many very important points to speeches are left out because they are not divisive and they are thus less thought-provoking. i found an example of this in my local newspaper this morning. the majority of the article explained dean's criticisms of the republican party, which were actually not very many. most of the time he spoke of other things, but after reading the article, one would think that dean was just venting at the right. i happened to get some nice pics. for the sake of saving bandwidth i'll only post one tho: comments anybody?

speaking of the uneducated... are you implying that all actors are stupid? are you implying that unintelligent people compose the left base? and really, moore isnt quite the satan you make him out to be. his facts were, in fact, just those; facts. yes, he put a nice little "spin" (i used that just for the republicans out there) on things, but the facts were accurate.

at the same time, you have to consider the ideal gas law...

oh, and with regard to bad experiments... when i was young and naive i titrated some incredibly conc fuming hydrochloric with draino. yeah im cool:\ i didnt read all the ingredients and missed the part about sodium hypochlorite being in it. i was doing this near my face so i could get a nice view of the reaction. i took a nice deep breath of chlorine. coughed for a few minutes i always seem to have difficulties with gases. last time i opened a lithium battery i smelled something (in retrospect it was probably diethyl ether). that was no fun either, as i got a bad headache. last time i was extracting potassium perchlorate from match heads i got a nice breath of some odd congealing agent. when i was significantly younger and significantly more naive than mentioned above, i made a nice potassium nitrate+sucrose smoke bomb. it didnt light quickly for some reason or another. so yeah, i just sorta stood over it waiting for it to burst into flames, and i tried to convince it to start. then it did and i got a complete lungful of carbon dioxide. i got an acid burn on my hand from working with that conc fuming hydrochloric once. also ive noticed that i have a particular weakness for the element chlorine. any exposure to an oxidized form of it (or neutral as well) makes my throat sore. of course the anion isnt cool if it's hydrochloric but hey, i have no problems with sodium chloride.
