H2SO4

well, among other reasins, people wear sunglasses so that they can "check out" the opposite sex in public without it being obvious. Anyone with sunglasses has done this.

IN eighth grade we did all lame labs. I did things at home that were WAY cooller.

There are three electron guns inside your television. I always thought an electron gun was almost, or exactly the same thing as a cathode ray tube.

you mean you want close to pure calcoium carbonate?Are any of these soluble in things others arent?do any of these doecompose with heat? Are they different particle size?

Ive been reading along, and it makes sense now. Now im curious, what will my computer performance be if I disable hyperthreading. How much do you think a dual coare processor e cost? Whats the speed they run at?

ya, i agree with you why things dissolve faster. That makes sense.

maybe granulated Mg mixed with some oxidizer to for a powder. This should burn extremely hot. If you do this, dont grind, its potential flahs powder.

so whats up with these "daul layer" processers. Supposedly there two processors in one. Please correct me if im wrong. Intel just recently released them. Would this be any better than Hyperthreading?

Whats it smell like? I imagine it smells like an pool when you take the cover off.

You have to know how to use it. I believe theres instructions.

I always thought of dissolving as the molecules of (lets just say NaCl) go in between the molecules of (lets just say, H2O). I always thought if the H2O is hotter, theres more space in between the molecules, thus more NaCl will fit in between. When it cools, there pushed out of there spaces. Please correct me if im wrong, i think it is more complicated. If it is wrong, it is a good, simle way to look at it.

maybe your Bi had some contaminations in it. If you heat your Bi to long, it will eventualy get ugly. The secret to the buitiful colored oxidation is not to overdo the heating process, but stop it when neccasary.

I have ignited thermite before with Mg ribbon. I think its all about placing the ribbon correctly.

I'm sure they have people that contstantly moderate new entries.

so, the wire is the seed, not the oxides, or loose bits of copper on the wire?

so why does Cu initiate crystal growth? is it from copper contamination?

Lead from fishing weights, but not to pure

lets see, what can you find inside a television. Isnt there a tungsten button or something inside cathode ray tubes, which are in televisions.

silver solder is about 97% Sn.

chill newtonian. Im 14/M/USA

wait, is this like an aerosol can?

Yes, you wouldnt want any gaseous piss escaping.

id imagine, to stay strong at high temperatures it must be pretty pure. plus, any contaminants might react at such temperatures and cause the filament to break. You can find neodymium-iron-boron magents in good speakers. Theres so many but their not pure.

ya, i guess they make some of those chips out of 99.999% silicon. To bad it is processed though, and doesnt realy look like elemental silicon. Oh, tungsten from lightbulb filiments. To bad its such a small amount, so forget it. hydrogen from electroysis of water. Also O2 from same method. sulfur form the pharmacy. just go here and look at his element colection for ideas.

reasonably pure copper from electrical wire. Carbon from pencils. silicon from pc chips. lI FROM BAttery's. Theres more.
