Your welcome. There are others but those three have kept me safe now for a long time, I also use Firefox so I feel even safer! And with the new version of Zone Alarm Pro it has one built in which is also pretty effective Cheers, Ryan Jones

Spybot Search & Destroy, Ad-Aware and SpyWare Blaster are all great and work in Win 98 Cheers, Ryan Jones

Firstly welcome to the forums! I'm quite shure your not allowed to have this stuff then again maybe you are :S Have a read here for starters: http://en.wikipedia.org/wiki/Tritium shows that Tritium is normally made by bombarding a Nitrogen 14 atom with a neutron though bomdarding duterium works just as well Good luck with making Tritiun anyway, Ryan Jones

I though I'd start a thread to show how greatful I am too the people who have helped me here at SFN in the hope that others will do the same. Firstly I'd like to say thank you to the staff who do their jobs with a great deal of enthusiasm and show a remarkable ammount of ability, everything you learn something they know something that is beond what you know - brilliant! Also thanks for the understanding you have shown and remarkable patience with me Secondly to the members who have helped me, there are too many to post here and seeing as I can't list them all I will not post any and you know who you are so thanks! I'd also like to post a special thanks to the chemistry experts and other members in the chemistry forum, thanks for understanding my abilities and thanks for helping with my mistakes and correcting me on them - you have helped me gain a lot of knowledge in this area and you know who you are - I don't think I need to post names! Finally, thanks to all the members who have posted in my threads and you are the people that make this forum what it is and what it will become! I'm not going anywhere I just thought it was time I showed my thoughts for all the peopel who have helped me and who will help me here in the future! I just hope I can help enough people here to makeup for all the help you have given me! Cheers, Ryan Jones

In a way it does but not that kind of cold, you'd need your whole body to be cold, not just a small part of it The reason is when you get cold your heart rate goes down to conserve energy, when this happens all un-nessisary facilities are closed down and the immune system cna be affected by this but its not true for drinking cold water Cheers, Ryan Jones

It would be interesting to say the least. I'd also like to see an imaginary number base, that would also be quite interesting! Cheers, Ryan Jones

You may also find this interesting http://mathworld.wolfram.com/topics/Non-EuclideanGeometry.html but I an afraid I can't help you with any books Cheers, Ryan Jones

Not in this age, in the past it could have been as non-heated water would have had some nasty bacteria and other microbes in it so it could have made sence then but we have stuff added to our water sothis point no longer works . Today I don't thnk this is true at all as people have ben doing it since we evolved and a long time before! Cheers, Ryan Jones

Apparently it does! but it does not seem to in some forums! Cheers, Ryan Jones

Ah, I see - thanks woelen. So if you know the type of the compound, e.g. chlorate you can probably say its ionic? Thanks Cheers, Ryan Jones

Hi there everyone! I know that is you take say Caesium Fluoride, even though this substance actually formcs covalent bonds the difference of the electronegativity of the elements ([math]E_d = |(x_a - x_b)| = |(0.7 - 4)| = |(-3.3)| = 3.3)[/math] means that it actually has more ionic character than covalent [math](E_d > 2)[/math] and so is classed as such. My question is how would you work this out for molecules with more than two atoms / molecules bonded together? Say with something like Potassium Nitrate, would you need to work out each bond in this seperatly or is there a better way to do this? Cheers, Ryan Jones

http://www.webelements.com/webelements/elements/text/Xe/key.html And on Krypton: http://www.webelements.com/webelements/elements/text/Kr/key.html Unless you have some pretty high tech equiptment you'r not going to be abel to use that method anyway! If you did have access to a lab there are other more compex methods that oen cna use (One involving a centrifuge and one involving something simmilar to a mass specrometer.) Cheers & Good Luck, Ryan Jones

Ah, I see - thanks for the explination (Makes more sence now ) Cheers, Ryan Jones

Thanks for the link donkey, I'll aheva read when I finish my Chemistry homework Cheers, Ryan Jones

I signed up for that too, I wonder if they really do save that area of the Amazon because you signed up... if they did get everyone here to sign up and that would save a lot of rain forest Cheers, Ryan Jones

No, its because of the preassure differences. If you have a bottle of somehting like compressed butane from the portable burners then shake at back and forth it will get VERY cold but as soon as you stop it returns to normal temperature Like I said its to do with preassure differences though i am not 100% shure as to why Cheers, Ryan Jones

I've heareed of that one form a book called the science in science fiction, its an interesting idea and its one of only 2 good uses for nuclear devices Like dave said the hard part will be the shielding and the fact that currently nuclear devices cannot be detonated in orbit. Cheers, Ryan Jones

What you said there makes no sence at all, can you restate the question by any chance? As aj47 said any liquid gas is really, really cold. On an interesting note, Helium is the only known substance that does not form a solid at standard preassure. Cheers. Ryan Jones

Good point, that rules does exist. If the questions were in the correct place they could be better answered Cheers, Ryan Jones

If you consider a photon as an energy transmitter then yes, every part of the EM spectrum is made of photons and the lower the wavelength the higher the energy they contain. Photons give energy too the electrons of the atom as they are absorbed and so, they do have a heating effect on the atom and the substance (I think anyway). For more informaiton this may be of interest: http://en.wikipedia.org/wiki/Photon Cheers, Ryan Jones

True but from my experience I know that a little of help does good too, provided the minimulm I could and I did not answer the question, all the explaining and reasons for it etc. have been left out and by giving hints you encourage the person too look for an answer themselves, simply not answering or helping at all will have the opposit effect in most cases Also, if there is a rule not to do his then I appear to have missed it and will not assist in homework questions in the future but I can't seem to find the rule anywhere. Cheers, Ryan Jones

Its an interesting idea but it will probably not be added for the same reason(s) as the img tag is not enabled. 1) It will slow the page loading times with a load of images in threads. 2) People may abuse them and use way too many of them. Other than that its an interesting idea Cheers, Ryan Jones
