right, but you almost never see them. according to one of my books, iron can be found as Fe-2 in Fe(CO)4-2, as Fe-1 in Fe2(CO)8 -2 as Fe+ in [Fe(NO)(H2O)5]+2, as Fe+2 in FeO, FeS2, FeF2, etc, as Fe+3 in Fe2O3, Fe3O4, FeF3, FeO(OH), as Fe+4 in some rare complexes and FeO4-2 and as +5 in FeO4-3...doesn't mention +6 must be really rare i guess i have a project for when my KOH(s) comes

apple computers pwn buddy

well.....i wouldn't say that...formaldehyde and glucose have the same empirical formula but theyre totally different
-
well, had you heard previously of this? supposedly it works...the thought of it is astounding, as such would be an amazing oxidizing agent.
-
anybody here familiar with ferrates? supposedly barium superoxide and Fe2O3 yield BaFeO4... as well, molten KNO3 and Fe2O3 should yield K2FeO4 but hey, since when could iron chemically oxidize to +6??

Right-wing governments 'increase suicide rates'
budullewraagh replied to Tetrahedrite's topic in Politics
sad thing is that once they get there many decide that war isn't quite as cool as they had thought it would be. a good many people are converted to the left on the battlefield, only to die. but again, myopic fools support the right anyway, despite its failure -
i do. and about 2000 students at my school. and AB and BC calc, although only 2 teachers in the math department actually know calculus...

actually, we're just pissed off/depressed we really want our country to succeed and it hurts us so much to see it fail so miserably while myopic fools support such failure -
yeah jdurg, the peroxide would eat through the sword. i still think RP is a good choice

well, sulfur is mostly insoluble in water... so you just add water to your 90% sulfur, heat to make sure you get everything, mix it up a bit, then pour off the water and you are done with your ionic/polar solutes. another thing you could do is dissolve the sulfur in carbon disulfide, benzene or toluene

actually, look at europe -
that is moderately humorous. i was going to mention alkali metals but they would tarnish if left on a sword. considering the chemical and cellular makeup of blood, i doubt there is something you could use. however, if you want, you can use red phosphorus, which is friction sensitive. back in the middle ages it was sort of a mythical element. striking phosphorus with something hard causes it to explode, so you could have the sword tipped with phosphorus and have the phosphorus explode when the sword strikes a foe's shield/armor/weapon. unfortunately, you have the problem of your own sword blowing up nomatter what you use. also, you have the problem that the red phosphorus can be used once, after which it has exploded... i suppose it makes a nice tip for arrows and francisca throwing axes however...

i beg to differ with 3... -our school is falling apart, no joke, despite the fact that we live in an afluent area -our football baseball and basketball teams get loads of funding and always come in last, but our other sports teams (crew, track, xc, lax) get none -our music department is bloody poor and yet we send our entire orchestra to area-all state and we usually have the all-state concertmaster. we put on a benefit gala and our highest select orchestra played beethoven's 9th symphony and the select chorale sang it. it was intense...but the admin doesn't care -our principal, vice principal and other fake-principal-like positions are all held by former football jocks who have lived in this town their entire lives -our school board refuses to offer AP psychology despite the fact that 40 students want it, we already have the books required for the class and a qualified teacher who wants to teach the class -our librarians/computer lab monitors are bloody nazis -teachers for freshman and sophomore years are HORRIBLE -we have a physics teacher fresh off the boat from holland who believes that when you eat food, some of its mass is converted to energy by the equation e=mc^2 -our chem teachers are fake chemists and more mathematicians who don't know a thing about theory and applied chem -our science department is rediculously analretentive; on a chem lab last year, everybody forgot to add a coefficient of "2" to an equation and we all lost 3 points on an 18 point assignment...and this was a lab the teacher gave us on the last day before christmas break...sheesh

TCAP is tricycloacetone peroxide btw they are unstable because the oxygen is bonded to other oxygen, which is not too desirable. so, the excess oxygen is liberated upon decomposition. with regard to kallium, have you ever dissolved it in liquid anhydrous ammonia? makes for a nifty reducing agent and looks cool, suppsedly...plus there's also the novelty of knowing you have reduced potassium... i never have, for lack of anhydrous liquid ammonia and for fear that the feds would stop by thinking i was reducing ephedrine...which i dont do. btw i think that's really cool that the old potassium metal forms peroxides and superoxides due to its electropositivity

could be happy for the fish depending on what you use

i see, i see. so if one lacked morals it would be much worse. it is a lose-lose situation for the fish

that is correct: sum of mass of 0.1 mol Na+ and 0.1 mol OH-=mass 0.1 mol NaOH

isnt that mildly cruel?

some of them i strongly advise you to research before you go about trying to obtain them. some important notes: -dont go above bismuth until you have significant knowledge of radioactive materials/unless you wish to irradiate yourself -read up on the halogens before you try to obtain them; they aren't too pleasant -before you get angry at the fact that you electrolyzed alkali salts/hydroxides and the resulting metal readily oxidized, figure out a good means for preventing this oxidation (try inert liquids like motor oil or mineral oil, or inert atmospheres like helium, argon, etc) -be careful with the transition elements, as there are some pretty nasty carcinogens among them, and many are really expensive -unless you are really wealthy and dont care about your money, scrap the lanthanides -europium looks cool, but is also remarkably expensive -some elements you may want to breathe away from, as they may have high vapor pressure (eg mercury, bromine) -wash your hands before and after you touch most elements

well, car batteries but they're SO poor, as the lead sulfate is left and theyre messy etc. i just dont like using batteries for sulfuric aside from that i have no source. i was thinking about using the lead chamber process, however, to make some sulfuric
-
hmm, i just thought of a wonderful exotic thermite; silver fluoride and lithium, done in a helium atmosphere (hey, you never know, even, say, neon may be oxidized by the fluorine otherwise). who wants to make bets that you wouldnt even have to heat your components to get them to react? takers, anyone?
-
yeah, i have the same problem. we cant get any oxidizers where i live; nitrates, nitrites, chlorates, perchlorates, chlorites, permanganates, etc. they're even taking away simple common things like hydrochloric acid, which i rarely see anymore. theres almost no red phosphorus in match books...and i still can't find sulfuric acid either
-
i bet it burned lilac instead of blue:\ what were your proportions? how large was the flame in comparison with the reagents? btw jdurg, can you get nitrates where you live? i can't

sadly i have yet to. usually i just marvel at it. i used a piece of paper to funnel it into a 60mL bottle and the paper actually caught a bunch of the dust. when i tapped the paper to get the dust out, it flew up into the air...i love the stuff. seriously, if you looked at the bottle you would think it were a liquid. it even flows like a liquid when you move the bottle
