I have no experience with your reaction scales, so I'm not exactly sure what it is you're doing, but who knows maybe I can help. What is the reaction? Is it just ammonia + sulfuric acid? If that is the case then ammonium bisulfate would form before ammonium sulfate as the reaction proceeds, which would just be a simple acid/base reaction. You could control this just by stoichiometry (adding half the ammonia (before driving off all the water of course, because while you've got water around all the weak acid/base equilibria come into play.)) Also, I would guess that the pyrosulfate stuff would form if you heated it to drive off water, but heated it too long or too high (but you'd really have to heat the piss out of it). As for the rock hard stuff, is it water soluble? Is a little or a lot? I actually have no idea if we are on the same page.

what a coinkiedink my work involves improving the catalysts for PEM fuel cells actually direct methanol fuel cells I'm developing methods that alter the shapes of the catalyst particles so that only one crystallographic surface (for the most part) is doing the reacting that way we can see if we can't get 2,10,20 times the current out of a DMFC, and you can have higher power densities, you could power more devices with them i've gotten the particles, the hard part it seems is getting them onto the dern Nafion membranes without ruining them (heat and pressure and all). But, the bigger problem with DMFCs is methanol crossover, which limits the MeOH conc. you can use. So you have a huge tank of dilute methanol on the back of your laptop. but improvements are being made all the time ANYWAY..........

hehe! If you aren't 16 yet, then who is that in your avatar? This whole time I thought it was you.

HF:SbF5 is called "magic acid" but I doubt you'd hallucinate if you took it, (well, you might before you die) Conc. HCl is 12 M ( i don't know if that got answered) when you buy it in a bottle.

if yer going to split water, don't forget the electrolyte! http://www.science-projects.com/Electrolysis/eLysis.htm

oh, yeah, mineral oil will work (avoid silicone oil) but, even though H2 is given off , the oxides still hydrolyze to hydroxides

what the hell do base baths have to do with anything?

Lithium has the lowest standard reduction potential in the periodic table. This is not equivalent to first ionization energy, where cesium has the lowest. Sodium won't displace potassium because it's standard reduction potential is HIGHER than potassium's. Li = -3.040 V Na = -2.713 V K = -2.925 V Rb = -2.924 V Cs = -2.923 V Look up a table of reduction potentials. You will see that it does not follow a periodic trend all the time. And you'd better do it under argon or helium, because the metals will react with the air. You can't do it under cheap ole nitrogen because of the LiN3 thing. edit: hehe switched up the highests with the lowests

so, the theory says that as the universe has been expanding then light speed has been going through various phase changes, i like this theory because it solves a lot of the "cosmological problems" without invoking 'dark energy' and 'dark matter' and there's no fudge factor, 'cosmological constant' or 'quiescence' it was ridiculously fast in the beginning, then it phase changed and slowed to a different speed, we are in one of those phases now where light travles at 300,000 m/s to answer earlier posts, light travels at one speed (nowadays), period when someone says "light travelling through a medium" they mean that photons are being absorbed and re-emitted throughout the material, atom to atom, so to speak but light ONLY travels in a vacuum, and at ONE velocity

Look up Michael Denton and all you get are creationist websites he's not a real paleontologist

as for Li displacing K in KCl are you talking about Li + KCl --> LiCl + K ? Look up the standard reduction potentials Li --> Li+ +3.040 V K+ --> K -2.936 V ---------------------------- +0.104 V It's positive, by god, and that means it's spontaneous (at STP). So Li will displace K in KCl to form LiCl. Also, look at the differences in lattice enthaply. LiCl is more stable. KCl = 715 kJ/mol LiCl = 853 kL/mol Based on that (if you did this in an inert atm) then the reaction should go.

OK, this discussion is STUPID!!!! When talking about activity/reactivity it's all a relative thing. If I were to take a chunk of lithium and chunk of potassium into my nitrogen filled glove box, then as for the metals reacting with the nitrogen LITHIUM wins, because lithium will react with the nitrogen to form LiN3, the potassium will not react at all. If I then take a chunk of lithium and a chunk of potassium into an argon filled glove box and heat them both in the presence of graphite POTASSIUM wins, since at atm pressure lithium will not react with graphite, but potassium will to form C8K. Thank you.

Oh, well, i would point out that he didn't address the point at all. (The foxes started looking like something else, not so much like foxes anymore, when bred for tameness alone.) You can't just talk about one little piece "evolving" on its own. If our ancestors were simpler beings they wouldn't have half a heart, or half an eye. They would have a more rudimentary organ. One that preforms the function, but maybe not as well as the later, more sophisticated versions. Or, more precisely, it performed the function to the requirements of the organism, which was to our perception, simpler. Tell, him to google: "planaria eyespot" to see simpler eyes, "insect ganglia" to see simpler brains, "insect heart" to see simpler circulatory systems

OH! I remember hearing the Young Ones discussing their O-levels!

hmm , most chromium salts are green (or blue) don't know about the oxides, but i think that chromates are usually green or yellow (or orange, pot. dichromate), i think CrO3 is yellow nickel salts are usually green too, don't know about the oxides i made some big fat crystals of nickelocene one time (20 electron complex) and they were a nice hunter green copper nitrate is green too ???

cool, thanks!

I've heard poor Luis de Broglie's name pronounced more ways than I care to think of. Does anyone know the correct pronunciation? I have always thought that the g is pretty much silent, and the lie part has a "yeh" sound to it. As in : " de Broh-yeh " Also, when I see "Euler" I want to say "you-ler", but I've heard someone say "oiler" before, is this right?

when are they going into lake vostok?? guess i could look it up, but just raising the question

If you could get something conductive to pass through the field lines, then you'd have some current (very little), but the earth's magnetic field is so weak in any one place that it wouldn't provide much power.

i have no idea what GCSE means, but, cool... glad to help!

i think the resolution of your eyes depends on the size and spacing of your rod and cone cells http://hyperphysics.phy-astr.gsu.edu/hbase/vision/rodcone.html basically, the rods pick up contrast and the cones pick up color, whether you can relate your eye's resolution to them is another matter, but your brain makes like it's all continuous anyway

yeah, they should separate pretty easily since magnesium sulfate is so much less soluble than copper sulfate (f for americans, i guess) you should get colorless (white) crystals in a blue solution, if it gets cloudy, then try adding a little more water (but not too much) to dissolve the MgSO4 back up (if you want larger crystals)
