  1. ya, ive seen that before, proably alot of other stuff is in it.
  2. DId you know you can start a new thread? this just totaly interupted this one. As for the metal thing, i think if its metal it metal, if its non-mrtallic its non-metalic. To me Cesium is just as mettalic as iron, copper, silver, platinum and tungsten. My favorite metal is probaly copper. I love the color and its properties. My favorite non-metal is probaly oxygen. As for you question lorie nelson, now that youve removed the iron, you could proably use density to seperate Pt and Au. There both very dense but Pt is more dense. If that doesnt work your last resort would probaly be aqua regia, but that would suck because you dont want to waste gold. Although, platinum is of higher value than gold (i think).
  3. So if you get oxidized by H2O2 you have necrosis because its killing living cells? Or is necrosis when cells just start dying quickly from a trauma and keep spreading?
  4. wow, that meteorite is stunning.
  5. Astatine does exist. It exists only for a few nano seconds at the most and can be found in the decay chain of i think uranium. Its just that there cannot be enough of it to be visible.
  6. Lol, or fluorine!
  7. ok, a layer on the bottom which can then be sucked out with a tube or something
  8. It's bp is only slightly higher than room temp at normal atmospheric pressure. If done in an ice bath it might form a layer on the surface if the method where you bubble Cl through it. First we went from talking about makingf iodine to bromine. This is a trend or something. What have you started Akcapr!
  9. what is alpha iron. An isotope? But then it would be worth thousands. I dont know and i know its most likely not an isotope but ive never heard of gamma or alpha iron. Explain then we may be able to help you better.
  10. Ive heard that Br produces painful sores that heal very slow. Whats necrosis?
  11. Id try bubbling chlorine through NaBr solution. Br might precipate out or form a pool of Br at the bottom.
  12. seems logical. But it would also oxidize skin cells probaly if it oxidizes single-celled organisms
  13. im trying to figuer out how that could possibly be good for you
  14. Realy, it goes away quick for me. Akcapr, your mom you'sed to give you a bath with KMnO4!!?? Wouldnt that terribly stain your skin and/or the tub brown?
  15. I was wondering why it was sold in pharmecies. Why is KNO3 sold in pharmecys. Is it another antiseptic?
  16. Has anyone here ever been severely burned by chemicals? I know there was a thing on the news about some women who got a thing of acid dropped on her head and it "severely maimed" her. I dont know what to think becasue i cant believe a thing of acid can screw someone up that bad pretty quickly. The only thing i can think of is like if it was peroxymonosulfuric acid (conc.?).
  17. Ya, KNO3 gives a strange sting on little cuts and abrasions. I work with black powder alot and it always gets in my cuts.
  18. H2SO4

    Lasers

    i dont see why not. A longer pulse means 1, and a short one means 0. binary code. I dont see why not.
  19. I just remembered when you heat KMnO4 it turns brown after it gives up its oxygen. SO it must be an oxidation reaction. Oxidation of skin, creepy.
  20. I was wondering what causes KMnO4 to stain skin so horribly. I was making saturated solutions of oxidizers to dip cotton string into to see how strong each oxidizers where (and just for the hell of it) to make fuses. Although nothing faces up to black powder rolled in tissue paper. I always get lightly stained by potassium permanganate and try to avoid it, but this saturated solution was so crazy, the second it hits skin it leaves brown marks, even if contact is for even a second, its very quick. I dipped a bit of steal wool in the solution to see how fast it would burn when dry. I put the steal wool on a firebrick and set it on the ground in the sun to dry. About 10 minutes later i came walking to my garage BAREFOOTED and stepped on the steal wool. All my toes are dark brown and alittle in the area underneath my toes. The stains dissipate after about three showers so i dont realy care, but i was wondering what causes this? Why is it purple then goes brown? Is it some kind of oxididation reaction. Also, when you get conc. H2O2 on your skin, it seems to bleach the local area, and sometimes slightly blisters, but i dont understand it because it reverts to normal within 1/2 hour. I know i shouldnt be getting chemicals on my hands, but it just happens sometimes. The only thing thats actualy ever caused pain was the conc. H2O2, but even the it was very little. I once had a wet knuckle and some NaOH pelets got on it and started to sting, but never auctual even caused a red mark. Ive put tiny amounts (i mean like half drop) of conc. H2SO4 on my skin and let it remail for quit some time, and nothing happened at all. My only explanation is that chemicals are only "skin damaging" if the area is large. I do think that people over-exhaderate on how dangerous chemicals are on skin contact, now eyes is a whole different thing. There delicate. All in all, this post was originaly intended to fimd out what causes KMnO4 to stain skin and turn brown.
  21. idk, but if you want gmail just ask me and ill happily invite you
  22. ok, send me pm with your email and ill give you gmail
  23. do you want one
  24. Ok, the first five people that respond to this thread get a gmail invite. I have 47 of them and i understand so many people have gmail now there getting "not so special" so i figuered ill have some fun. If you are one of the five Personal message me with your email and ill send one asap. This is kinda like an auction but without money. BTW gmail has upgraded to 2150 mb per inbox. I remember when it was one gig, now its over two. They gotta keep up with the competition.
