  1. ok i've got one, You've probably all heard it before, but anyway: A man is walking in the desert, he is captured by some local tribesmen. They take him to their king. The king says to the man: "you have a chance to say one sentence, it has to be true or false. If you say a true sentence I will kill you quickly,If you say a false sentence, I will kill you slowly." The man says one sentence, and the cheif has to let him go. Now I've heard many plausible answers to this riddle, all correct, and because of that I'm only going to accept the one I'm thinking of HEHEHE have fun with that one if you dont already know it!!!
  2. Ahh, I see That would make sense, lol
  3. One of my friends studying chemistry at university further explained the situation to me: You said antimony pentafluoride isn't an acid,but he believes (not having studied it intensely), that it IS a Lewis acid. However that is not relevant to this discussion. The reason it is not a normal acid is because it doesnt make H3O+ in water, thats where the acid loses a proton to water, and forms a conjugate base, I.E: {H2SO4 + H2O ----> H3O+ + HSO4-} The presence of H3O+ makes a solution acidic, in Antimony Pentafluoride though, the conjugate base is EXTREMELY stable, so you end up with free protons running round in solution - something that never usually happens, because they cant exist on their own so you end up with: {HF + SbF5 ------> SbF6- + H+}. I should also specify that HF is a liquid, and not aqueous Once again, I hope this explanation helps.
  4. Ahh well, complain to Guinness. There beer isn't too bad, but I guess they should get their facts right first!
  5. I can see both points to this discussion. Im sure though, that If a 1TB CD was made, it would be re recordable, I think it would be quite stupid for a disc that big in common manufacture is not re-recordable. I can almost guarantee that 90% of people who use a computer would not be able to fill a TB CD in 1, as is neccesary with all CD-R's and DVD-R's. In some cases I need smaller storage, and in others I need larger storage. Most of the people I know use MSN, and those who don't tend to have an email address. I'm still on dial up internet, (Bloody countryside!) But I find it no problem to send a 1.44mb file over the internet. Sure it may take me 10-20 minutes, but that's not a lot of time. I think floppy disks are becoming more and more extinct. My school has just got a new computer suite: P4 3.2Ghz, 512MB DDR330 ram and 80GB Hard drives. Not one of these computers has a floppy drive. (Maybe it's just that they're crap computers, but I do think that floppy will be completely gone in a few years) However, when some of my more fortunate friends who happen to be on broadband ~Cough BASTARDS Cough~ download things that I can not, often these amount to more than 10GB, and thus result in needing more than 1 DVD. In this case a 50GB DVD would be ideal, but in my opinion, CD's should be kept for those files that are a bit to big to send even on broadband, DVD's should be kept for those movies and files too big for CD's, and a larger DVD (Such as the Blu-ray) should be more widely available. And as for those people whining about 3MB files being too big to be sent by email on dial up: Put up with it, I have to!
  6. Just checked, I'll quote from the Guiness Book of Records 2003: "Normal solutions of strong acids and alkalis tend towards pH values of 0 and 14 respectively, but this scale is inadequate for superacids, the strongest of which is an 80% solution of antimony pentafluoride in hydrofluoric acid (fluoro-antimonic acid). The acidity function of this solution has not been measured, but even a weaker 50% solution is 1,018 times more powerful than concentrated sulphuric acid" Now, that's not one I'd like to put my hand in!
  7. I'm not 100% sure, but I think the strongest acid is antimony pentafluoride.
  8. I tried posting something about this a while ago, but no response, so I'll try again: Has anyone heard anything about octanitrocubane, I've read everything there is from the chicago university website, but have not been able to strain any more information out of the net. Im sure its there, just I can't be arsed to find it Also, I was wondering if it is possible for it to be synthesized. (By someone with access to a lab, obviously I'm aware I couldn't do it in my back garden, and I know it can be done with access to a lab like that of Chicago university, but is it possible for someone who works at say an upper (High) school chemistry lab to synthesize the marvel? Any replies to this post would be much appreciated Regards Ld
  9. Try using your potassium perchlorate to see how much energy is in chocolate Its always fun
  10. Also, If anyone can help on my formating problem aswell, I would be very appreciative. Oh, and its not as simple as re-installing windows with my windows XP Disks, as I never got any, (Bloody Budget computer) and still don't have any. All I have is the format disks, one cd drive and one knoppix CD. Regards,
  11. Has anyone heard of an os called knoppix/used it/is using it? My old computer really screwed up, and I partitioned the Hard Drive, but made the partitioned side without windows the primary one, and consequently, I can not format the hard drive, but thats another story. I have a copy of knoppix on disk, and my old computer only has one CD Drive, so I don't know how to install any disk software. If anyone can help on this, again, as always, it would be appreciated. Regards,
