  1. as for the soil, chlorates have been found in it, AKA weedkiller. so it`s probably not the Best idea to use the native soil anyway

    Number Bases

    I used to think Octal (base 8) was a pretty obscure counting system until I needed a output display for a prototype computer I made and didn`t have any BCD to 7 segment decoder chips and had to use straight decoders and bit 4 as carry, then it all made sense Decimal would have been nicer from a laziness perspective, but after a while I got used to thinking in octal as well. although I can`t envisage any practical use for a .5 based system??? at least nothing that can`t be performed in another more suitable base.
  3. the yellow "safety" flame is about 1000c, you can add a couple of hundred extra for the blue flame.
  4. I used to get exactly the same sort of thing (without the anger, just the panic effect) when I was in my early 20`s, get your blood sugar levels checked out as well as Iron and Vit B. sadly the problem snowballs psychologically, because after it`s happened a few times you associate it with things because the feelings are so intense, and these things can trigger an attack with or without the original cause being present latter. I`d rather not share How I managed to get myself past this condition/cycle as it`s medically ill advisible to do what I did, but I`m sure a trained professional will know exactly how to help you
  5. some things burn rather well in CO2, dry powder is usually the best to have around in a lab (at least that`s what I have in mine).
  6. what do you want it for anyway? there May be an easier route to get to your final product that doesn`t involve NaBr.
  7. maybe not for Cooking per se, but as a knife blade it might be ideal, you can already get ceramic blades, but non-stick as well? that would be Great!
  8. I think it was established through experimental means rather than mathematically.
  9. a simple salt water soln would provide the chloride needed. if it goes cloudy white, then it likely contains silver.
  10. sounds like Copper to me, perhaps a Brass, especially the chlorides then oxides. perhaps it`s been coated with something? try dissolving in Nitric acid, and then add a a weak chloride soln to this, look for a white PPT, I`v seen Silver (alloyed with copper) have this effect. did all the powder dissolve when you did the HCl addition?
  11. if the above is True, then how the hell do you explain the patriot act that Actively persecutes home chemist/scientists and deprives them of their Liberty and property? and they get no "due Process"!
  12. if it didn`t react with the NaOH then it`s not Alu, another idea would be to crystalise your green soln and look at them under the microscope, their shape and color can be very revealing.

    Being open minded

    I think it`s only possible to be closed minded in very narrow catagories, by it`s own nature; to be Broadly closed minded would disallow the learning of Anything in the 1`st place to be close minded about. with the possible exception of most teenagers, they already Know Everything
  14. WD-40`s pretty good for most things, but it will take quite a bit of time since it cannot penetrate Through the decal itself.
  15. isn`t 5 the forth prime number?
  16. solder a wire onto one of the output needles of an air ioniser, then hook that up to your conductive fence/cage.
  17. I`st of all you don`t mention what color the powder is, is there a reason for that? a green soln does however narrow it down somewhat, now try using sodium hydroxide
  18. it`s important to remember what Cinnamon actually is, it`s Wood, or more specifically the Bark off a tree, so it probably contains cellulose as well as other goodies.
  19. it want`s an Extra one to make 2, yes.
  20. you can add some Barium or Calcium carbonate or hydroxide to it until the pH is neutral, then evaporate all the liquid off. then you add the remainder to sulphuric acid, and hey presto, you have Conc HCl. it`s hardly worth the effort, but that`s how to do it if you Really wanted to.
  21. I was forced to go today (my wife made an emergency appt), I`m already stone deaf in both ears as of thursday morning and the Pain on Friday night was unbearable (I don`t say that lightly), on Saturday it turns out that my left ear is now bleeding as well anyway that dosage thing has been a moot point as I`v been eating the 30mg tabs like candy. I`v been given yet Another 7 day course of amoxicillin (the stuff that didn`t work last time) and some 10mg codiene tabs I`v seriously considered going into the city and buying a bottle of methadone off a junky when these 30mg`s run out, this pain is driving me insane! and if something doesn`t get done about it the next time a quack sees me, I`ll need a script for anti-psychotics!
  22. actually I always thought that it was Space that bends due to gravity and that the light within that space was traveling in a straight line?
  23. Thanks each, it`s nice to have my logic is confirmed as reassurance, and I also managed to get a bit of sleep last night as well because the pain wasn`t as bad. the funny side is that my middle ear is also affected by this "bug" so badly that I might as well have taken the large dose for all the good it was trying to stay clear headed and balanced
