i can tell you a number of methods, but i need permission from the mods first. what do you intend to use the potassium nitrate for?

it doesnt work. give it up.

mccain has become a whore to the extremists douglas, bush isnt anywhere near the greatness that was fdr. i think the ignorant have had their time screwing the us over and that by 2008 we'll be through with this hypocrisy

i strongly advise you to not make nitric anhydride. it comes back to haunt you later in life

check out his speech at the DNC on nytimes.com

you would need to buy an ultracentrifuge (several million US $), and uranium dust wouldnt work. first, youd die. second, and more importantly, the fact that there is a greater surface area doesnt negate the fact that some uranium/plutonium fragments would block some other uranium and so the plutonium in the front would just undergo fission

have you heard any of his speeches?

which is an interesting concept in itself, considering hahn did have urananite ore. good thing he didnt understand solubility rules and ended up with a mixture of the ore and conc H2SO4/HNO3

"drip it into a bottle of like neon" argon and helium are significantly cheaper. "Yes, but its at least 13 times more interesting than a nail." agreed. "So you just take the external layers and polish them off. The iron that is not exposed to the surrounding air cannot be oxidized." true, that, although it diminishes product quantity

hahn never made Pu; he used radium-226 and beryllium through tritium (after trying americium-241 and aluminum and failing) on thorium 232, which accepted a neutron and became thorium 233, and decayed to protactinium 233 and finally to uranium 233. the problem is that even if you make plutonium, you'll make the atoms split as soon as they are formed, or so probability says. plus, you have no idea when an atom is going to decay (schrodinger's cat) and without an ultracentrifuge/beast of a mass spectrometer, you can't do anything.

it's second nature. i can predict the properties of just about anything, save a few macromolecules, namely proteins and the like that are receptor specific. hard to explain.

it's cheaper at 35% by the liter. i can get a grand total of something like 22mL of 100% h2o2 for maybe $1.50 at a local drug store. of course, it's diluted to 3%. i got a liter of 35% for $17. not particularly cheap

pangloss is a liberal? ack, what is this platform coming to? out of curiosity, why are the two of you not enamored by obama? btw, rice is pure evil

you shouldnt get a good yield of iron at all. yes, you get the molten metal, but it oxidizes easily at such high temperatures

"Please help! I need to know how you can use the periodic table to make predictions of the soluabilities of compounds of groups1 and 2 ... and also 16 adn 17. mainly magnesium carbonate, sodium carbonate, potassium carbonate, and calcium carbonate... and also copper (II) oxide, copper (II) chloride, copper (II) bromide, and copper (II) sulfide. PLEASE HELP! " MgCO3 shouldnt be particualrly soluble, as carbonates tend to not be very soluble. Na2CO3 should be soluble just because of the Na+. same goes for K2CO3. CaCO3 should be mostly insol because it's a group 2 carbonate. cupric oxide should form the insoluble hydroxide. cupric chloride and bromide should be slightly soluble. cupric sulfide shouldnt be soluble.

aww, h2o2 is so expensive tho

just a note to reply to h2so4's post. if you try to do a displacement reaction with a more active metal than Mg, it will react with water. if you try to do it dry, it will be an insane thermite.

dean obama '08!

it depends on what glassware you have. you could try a number of methods; if you have a strong fan, you could push air into your reaction vessel, but it could get tricky. make sure the fan is strong and you have a reasonable amount of space for the SO2 to diffuse out and into the solution.

i wouldnt suggest that:\

magnesium nitride shouldnt form in any remotely significant quantities unless you were to add much heat and pressure to Mg in an N atmosphere

thorium is actually available, but im not going to get into that. myth: terrorists are everywhere

and you can easily do a displacement with the sodium to get potassium. H2SO4+NaOH-->NaHSO4 only in a 1:1 ratio stoichiometrically. same works with KOH. S+O2-->SO2 SO2+H2O2-->H2SO4 H2SO4+KOH-->KHSO4 ^i wouldnt suggest the above just because the SO2 isnt friendly, or so i've found in my exposure to it. if you were to try this, i would suggest you try to keep the peroxide very cold, as dissolving the SO2 is an exothermic process and could cause the runaway decomp of the peroxide.

"The problem is, sodium nitrate is an ionic solid so it will only dissolve in a polar liquid." i would disagree, as it is soluble in glycerol for example, which isnt so polar at all. also, is it soluble in pyridine?

U233 is fissile, and not as difficult to produce as one may think (david hahn) although it is difficult to isolate various isotopes
