So in SiC the silicon and carbon atom share all their electrons? If so, it seems that SiC is a compound for communists.

Umm, isn't that bloody hard to do? :|

Thanks. Aren't there also double (or more) electron bonds? Like a carbon atom forming double bonds with two oxygen atoms making carbon dioxide? Or am I way off here? :<

Just noticed that it's not probably used anymore: http://www.theodoregray.com/PeriodicTable/Samples/053.7/index.s12.html That's 93% iodine (10 grams of resublimated iodine plus 3.5 grams of potassium iodide) and it's "said to be antique".

Well, the medicine I talked about is in crystal form but it's about 98% pure.

Hmm... If you make nitrogen tri-iodide, it won't even explode if the iodine is >99,99%? Or was it the other way around? Horse hoof-ailment medicine is like 98% iodine, so if it's that way, it should work just fine.

So if an atom has four outer orbit electrons, it can have them all shared with for example four fluorine atoms? This stuff is taught in Finland like in the second year of high school or something.

"Graphite for leving www.scitoys.com" I knew about that page, but I haven't found pyr. graphite at any other site. :<

Yeah, in the nuclear war scenario, the nuclear winter wouldn't be nice for even the most radiation resistant species.

Let's take this scenario (which I think is disturbingly likely to happen): Nuclear war has ended. Just about every continent is a wasteland, mostly with radiation and toxic levels nearly unbearable to homo sapiens species. All mammals including humans become extinct within about 10 years or so. The interesting part comes first: Now that the sections in the food chain and ecosystem where humans and mammals used to be is empty, a new species will most likely take it over within a couple of hundred million years. But which species will natural selection choose to be the next "dominant" species? Highly radioactivity withstanding insects? Bacteria will start to evolve to something more? Just something to think about.

This is starting to get little "biologey", but do you have many natural blonde men in the UK? I am a n. blonde. :<

Well, they are not much use, unless you need to irradiate something fun, such as a plant etc..

I don't think sulfuric will decompose until 250, but I still don't recommend using over 200 C heat.

The 1g Be ball is brilliant, you could make a neutron gun easily with it. Edit: I wonder what FedEx or the like would think if you bought something from United Nuclear and sent it to me.

Hmm... The boiling point of 50%-70% nitric acid is about 122 C. So I bet you could concentrate it by boiling it with about the 80-90 C you mentioned.

H2O2 + (2)MnO2 --> (2)HMnO4 + O2 ? I bet it could work, but I have no idea what it produces with the permanganic acid. Could be O, could be H. No idea.

I think that's a good idea, just remember to first pour the water, then the acid. I also think it's way more simple to dilute near 100% acids with water than mess around with 60% or 70%.

Seems like a nice cave. The only I've been to is the Melidoni cave in Crete. "I``ve gotta go and do some gardening in the pouring rain now" It would be worth mentioning if it DIDN'T rain in England. Talking about rain, the worst acid rain has been measured in Scotland (can't remember the place), measuring about 1 pH.

I'm 192 or something and I'm 16 years old. :| Aspirin, my mother would like to know if the Postojna cave in Slovenia is worth of visiting. Have you ever been there?

I think they are the ones with the least color. I'd like to know if any company sells non-dyed matches.

Well, my dad's a psychiatrist and usually is somewhere all the time in conferences or the like (it's starting to get hard to name a country he hasn't been to). And if you're anxious to have kids, you can adopt me if you'd like to. Lol

Yes, I had some of that too (my dad bought two chemistry sets from US of A since they didn't sell them anywhere in Finland).

Unless you are able to heat it with a temp of about 50 C to vaporate the last H2O on a plate or something where it's easy to scrape off, just let it dry in room temp. Or, you could mix the sugar/whatever you're mixing while it's still wet.

Heh, the red cabbage juice is probably the most basic experiment with acids/pH. I remember doing it when I was 9 or something.

Yeah, it sounds like the kind where you actually do get a Darwin award, or at least an honorable mention.
