H2SO4

ok, thanks, just was kinda new and had never heard of it before i registered here. Also, how do people sighn in as guest. I never understood this at any forum.

Do you store your K in oil, because its not like you can wash oil of K with H2O. Id go with the same thing Akcapr says, eat bananas. Better yet just try eating alot of fruits, vegetables, juices and maybe some meat for a day or two before your tournament. I obviuosly dont know anything about human health, but thats what id do. If your legs are hurting try jogging frequently. Over time it realy helps your performance.

what is that whole latex thing. Its a sticky thread above this one.

so do i need a PC3200U stick? I do alot of multitasking so that would be great for more RAM

Im not a computer genius, but i do like computers and know a resonable amount aboput them. I had a old win 95 and it was the top of the line back then, and it totaly went to crap(like all computers). I have a nice dell (hyper threading, cd burner, dvd drive, pentium 4 with ht tech, 144 gig hard drive, 512 mb of ram, ect) and i dont want it to go to crap as fast as the last computer i had. I want to slowly upgrade it to keep it nice. The first thing i want to add is a some RAM sticks. I understand that you need to get the same type of ram thats in there or it wont work right. I wrote down what was on the ram sticks and wroe it in notepad. Im sorry if its kinda crude: RAM STICKS: BRAND: INFINION IT SAYS 32Mx64 CAPACITY: 256 MB, DDR, 400, CL3 THIS WAS ALSO WRITTEN ON IT: PC3200U-30330-AO(OR ZERO) Im posting this because i want some one to explain to me what i should by. I want to upgrade my ram because i found out that it greatly improves multitasking and speed.

dude that sgonna take forever to dissolve 45 pounds of zinc into solution unless you have it in powder form or turning

I buy H2SO4 at the auto parts store for about 3.50 a quart. Seems like a resonable price. You should probaly look on ebay for nickel or a nickel salt.

dont galvanized things utilize cathodic protection also?

who would want to be in a partialy lead casket, isnt lead like the bottom of the crap, poor, metals? If i was the pope i would want a partialy copper casket that would be friggen awesome.

When i need graphite rods i usualy cant extract the graphite without alittle heat. What i do is take my blowtorch (bunsen burner will work) and burn apenis till the ashes fall of the graphite. Gives you a nice, unbroken piece of graphite.

Imade a propane/mapp burner. All i did was expiremented with burner heads, and from my home made burner ran a hose connected directly from the torch burner. The great thing about this is you dont even need to build a jet. I tried to build a jet (even tried pulling a tungsten filement through solder) and i couldnt get a fine enough jet. Use the torchs jet to mix the fuel with the air. After my burner was finished it was better than our rappy school ones. I just had alot of soldering for the burner.

He posted this a few days ago and didnt get any replies. Sucks for him becasue he didnt get the answer for his test. Tuff luck.

exposing bismuth to radiums alpha will make astatine? Thats interesting.

Hi, my name is Derek, im 14 years old, im here because i love science. I am an amauter pyrotechnition and i like chemistry.

i dont know off any intersting things to do with the stuff, does it have the phosporescent stuff in it so it glows at night, because thats cool. You can probaly get alot for it on ebay.

good way to put it.

Ive never used Dimethyle Sulfoxide, does it stink that bad, it is a sulfur compounds?

I like calcium carbide and water also. Quite exothermic too. Ca2C+H2O---->Ca(OH)2+C2H2 (ethyne) Makes acteylyne

Fortuna, i enjoy making my own chemicals, gives me something to do, and gives you a sense of accomplishment when your done.

no, i dont have a school that lets me use chemicals. My school doesnt have much anyway. All my nitrates are of the alkali metals, so those wont work, what about ammonium nitrate?

it might be hard to find that though. Start out simple, did you try rubbing alcohol, gasoline, white gas. If you want to get super complicated and Mind me for saying this, im just throughing it in here for discussion, Liquid propane.

CH32SO (DMSO, a.k.a Dimethyl sulfoxide) might works. Supposedly it an extremely good solvent.

Thats way to hard a question. I have abinch i like. Some of my favorites are potassium permanganate and glycerin, copper chloride plus aluminum powder, i know theres more, but thats kinda a hard question.

benson, i can braze with my MAPP gas burner. I have a homemade bunsen burner that can operate on mapp, or propane, it hooks into my blowtorch regulater. Real simple and it works.
