General Chemistry by Linus Pauling. Good in depth explanations of many chemistry topics. - http://www.amazon.com/exec/obidos/tg/detail/-/0486656225/qid=1131063688/sr=8-1/ref=pd_bbs_1/103-3007256-0599005?v=glance&s=books&n=507846

This says otherwise' date=' so who's right? It'd make sense for you to be.. But who knows.
EDIT: I think I have a solution. Please tell me if I'm right. The way I see it, theres a lot mre Cu than Ni in the crude metal. So Nickel if oxidized. When the Nickel Runs out, the Cu is then oxidized. Once all the Ions are in the solution, there is no lack of Cu2+ Ions, therefor the Nickel is never reduced. Is this correct? If it is, it looks liek I jsut answered my own question, and that feels good. Of course it proll isn't right.[/quote']
Yep, that's about right.

Very interesting. It's curious how ICl is similar to bromine.

The lead will plate out first if you try electrolysis. It would probably be easier to precipitate it with HCl than to try and determine when it is all out of the solution.

Oh boy, there's so many I could choose. Copper is great for its color and malleability and colorful compounds, Aluminum is great for its light weight, Zinc is fun for its castability and non-poisionousness (is that a word?).

Use draxxus paintballs' date=' and you won't get cramps!
Anyways, i would just eat bananas and other fruits.[/quote']
I like PMI Premium myself. Boy, it's been entirely too long since I've played, I really should go.

I'll bet there isn't any glue, or very little, it's probably just the magnet holding on for dear life. I'd take a pair of pliers and carefully pull it off.

Heh, mine was off by about five miles.

Cool, thanks for the guide.

You'll like Chemistry, its very interesting to learn and even more fun to put to practical use

How much formal chemistry education do you have? You could make a battery with all kinds of things (Iron Oxide and aluminum will work)
The Aluminum will reduce the Iron Oxide, making Iron and Aluminum Oxide.

If you can remove it and if it is a pure metal (no iron or other metals attached that cannot easily be removed), you could place it into a tank of water that is completely full, and collect the amount of water that is displaced out of the tank. Then, weigh the object, and the mass divided by the volume of water it displaced will be its density, which you can compare to the densities of Aluminum (2700kg/cubic meter) and Magnesium (1738 kg/cubic meter).

I have a silicon chunk, and it has a neat metallic blue color too.

It is incredibly hard to melt salt. Two propane torches on all the way could not melt much more than the surface of some I was trying to melt.

question for you budu' date='
if you have a bucket upside down in the ocean, and you bubble CO2 into it, so now you have an upsidedown bucket of CO2, and you tie a weight on the handle so it sinks.
How deep will it sink before the CO2 turns into liquid?
or if that doesnt happen what do you think happens
I am picturing the water temperature as somewhere between 4 and 6 celsius once you get deep that is.[/quote']
Well, CO2 will liquify at room temperature at about 800-900 Pounds per square inch pressure.

You might want to take apart some batteries to get the carbon rods in the center to use as electrodes, because if you use copper or iron electrodes, they can react with the oxygen produced to make copper or iron oxides which muck up the solution (which may also be why you only get one stream of bubbles, the oxygen is reacting with the electrodes). The carbon should be relatively nonreactive, at most making CO2 which is a gas and therefore not going to muck up the solution.

An astronaut, Jerry Ross, who has been on 7 shuttle missions grew up here.

For non-scientific measurements, I like the old system. Mabye it's just because I grew up with it, and am familiar with it. Quarts, Pints, Cups, Tablespoons, and Teaspoons are convienient for cooking, the mile is nice for distances, weight in pounds, and Fahrenheit degrees are nice. I would really have a hard time adjusting to the metric system for those kinds of things. Scientific measurements are a different thing, and the metric system is very nice for them.

Why dont u just go buy some...They sell it in stores and its prob a hell of alot easyer then wasting ur time to make something....
Where's the fun in that?

That stuff is fun. It's fun to show people that water can start a fire.

My physics teacher puts a fact of the day on the board each day and he put that on the board last Thursday.

what that really happens in water,i wear my watch in the bath which isnt water proof,could it burn my wrist..i fail to see the reference to drugs though who would want to eat lithium batteries for a high
I'm sure the batteries are well sealed because if they weren't, just the oxygen in the atmosphere could oxidize about all the lithium in the battery away to Li2O in a matter of hours or days.

Hmmh... You could separate hydrogen from HCl with lithium quite easily. I can't see why anyone would like to spend lithium for that purpose though.
You can get hydrogen from water with lithium, it's neat to watch a metal just disappear into a cup of water amid a bunch of hydrogen bubbles.

I've bought stuff from them before. They have good prices.
