Perhaps in the future they'll have nanobots (possibly with tiny lasers ) ) that can be released into your bloodstream, that destroy only particular organisms in your veins, for example HIV. (Or then there's the chance I've just played too much Anarchy Online :< )
-
EW = certain forum? If so, let's leave them run around in their own little circles shall we. Btw, if we're talking about common materials that are HANDLED commonly, I'd say nickel or zinc are good examples as they're found in many coins. )

Hot water freezes faster only if you throw it in the air, as it's partially steam, and scarce water molecules are easier to freeze than... less scarce water molecules. If you have a bowl of 50 C water and a bowl of 25 C water, with equal masses and so on, the 25 C water freezes faster. http://www.physlink.com/Education/AskExperts/ae7.cfm

"you know what a cool thing to do in the freezing cold(i did it in -20 F) weather is to take a cup of boiling water and just throw it and it freezes in mid air." Finland didn't really get that kind of temperatures this winter, but if the next winter's different perhaps I'll try that. And wouldn't it be more effective if the water was already somewhat cold?

Old planets might be good in the aspect of organism searching. Or not. Or perhaps advanced life anyway. Wasn't the oldest planet found somewhere near 10 billion years old? Although humans are probably gone in five billion years from now, some other species might not.

"One might argue that if it doesn't have a short name it isn't a common/everyday molecule. (common meaning common for the average person, not common for a chemist)" Yeah, for example some chemicals in the body are "used everyday", but they don't really have a shorter name. "malic and formic acid?" Hmmh? People use formic acid daily/commonly? Btw, malic acid is C4H6O5.

"Best thing to do in highschool is just completely ignore the class and study more advanced things all period. Generally teachers won't care, as long as you're acing all the tests." Can we have an amen to that?
-
"come now, thats just called 2,4,6 nitrotoluene" You want to do it the easy way, or you want to do it the hard way?
-
"i love organics. there are compounds with names that would go for 3 lines that we chemists would understand and put together. i love it" Yeah, got to hand it to organics. The 6,6,4-buty-whatever way of marking the structure is especially awesome, like 1-methyl-2,4,6-trinitrobenzene (TNT, C7H5N3O6). And the biggest hydrocarbons are cool too (for example C60H122, or hexacontane).
-
What if people said more what the molecular formulas actually mean in English - that would be nice. (Of course, only in cases where the compound actually has a shorter/simplier everyday name)
-
"I know people who trapped Francium. It eventually got away, of course." Yeah, I recall some people trapping it quite a bit. http://funk.physics.sunysb.edu/lab/frnews2002/more3.htm <- cool Oh, has someone mentioned aspirin (acetylsalicylic acid)? It's C9H8O4.

"Alternatively, even a primitive ladybird can be intrigued by the sight of Gilded swinging a number seven iron." Naturally, the iron 7 is my choice for a 1ft putt.

Are you using a browser that can block all pop-ups, or pop-ups from specific sites?

I remember practicing golf (it sucked though ), and the just recently cut green was full of ladybugs (or ladybirds, if you insist), and you could see more coming from the taller grass. What causes this kind of behavior? Were they looking for something?

Test for Chloride ions in Aqueous solution
Gilded replied to Redrang604's topic in Applied Chemistry
"(not sulfate)" Yeah, that's quite obvious. :> -
"these generally are the people who obsess over organic peroxides and "francium" which doesnt really exist." Oh come on, there's about 25 pounds of francium at a time on/in Earth. Btw, vitamin B-12: C63H88CoN14O14P - the coolest vitamin

"BTW, why is the "first day" you can buy fireworks in Finland? It is a local custum or a new law in effect?" I don't know how much it has been in effect, pretty long anyway. But now I checked the midsummer thing, and it seems that you can use fireworks on the Midsummer Day too, in addition to New Year's Eve.
-
I'm off to my friend's to dispose of my fireworks now. ) See you guys on Saturday, and a happy New Year to y'all!

I prefer the C2H5OH for ethyl alcohol (not that you couldn't figure out the shape of the molecule with C2H6O though).
-
"thats weird. so -126 is not that cold after all!!" Trust me, it is. They use that sort of temperatures for some sort of muscle and joint treatment though...
-
"Gilded was right. The second law, which holds for macroscopic systems, implies that fully adiabatic processes will not exist." Yeah, exceptions in the microscopic scale. Btw, did Maxwell's demon have something to do with adiabatic processes?

Over 120 000 overall dead announced, 80 000 in Indonesia... According to WHO, approximately 5 million homeless.
-
C6H12O6 is fructose. And C12H22O11 is table sugar, which is used in it's plain form. Let's see... gasoline's mostly hydrocarbons with 5 to 12 carbon atoms... and C2H5OH or ethyl alcohol is something especially Finns use very commonly. )
-
I know as much physics as the average squirrel, but I remember it having something to do with the 2nd law of thermodynamics.

I think grams are better than the pound/other stuff, as with the pound you have "stones" and who knows what. With the gram, you can just add kilo- or similar affix. Although we do have tons... Hmm. Perhaps we should ditch both and use a unit based on atomic mass units. )
