Have a look here and here Quite a lot of approximations and formuals in those two Cheers, Ryan Jones

I've never actually done a thermite reaction yet but I've used Amilinium to test its reactivity with various acids or bases. That Aluminium Oxide is a pain, makes Aluminium seem rreally unreactive Cheers, Ryan Jones

Graphite plates? Never heared of those only graphite rods. I suppose if they exist lab supply stores should ahve them if not then you'll probably have to contact a speialist to get hold of some Cheers, Ryan Jones

Indeed, it would probably be cheaper just to but pure aluminium powder Can't you just shred aluminium cans? I did that with one of those industreal shredders and it worked fine Cheers, Ryan Jones

Have a loom here Cheers, Ryan Jones

Umm... a lot. Maths is one of those things where you just keep on learning - I'll point you twards some good links if you want to look further http://mathworld.wolfram.com/ http://www.ics.uci.edu/~eppstein/junkyard/ http://home.att.net/~numericana/ http://www.dansmath.com/ Cheers, Ryan Jones

At what level are those questions set? If your looking for a site where you'll find the answers I'll point you to the one I use (Have read the whole site a few times) http://www.chemguide.co.uk/ I'd like to help more but I am no chemistry expert, maybe one of the resident experts can help you better than I Cheers & Good luck. Ryan Jones

I'll offer you a few sites I look at regularly: http://www.webelements.com/ http://81.207.88.128/science/chem/index.html http://www.chemguide.co.uk/ http://www.freewebs.com/akexperimental/ Books are another good source of interest I'm shure others have more sites for you too look at also Cheers, Ryan Jones

Not always but often reactiions involving one or the other can be quite vigerous And example would be Potassium and say Fluorine - that would be interesting to watch Cheers, Ryan Jones

Great practiacal YT2095 I'm going to try this one. I've got some Boron ordered but its not the same when you don't make it yourself Cheers and thanks for this (Will be trying this later today) Ryan Jones

Actually it can react with its self by forming trioxygen' date=' AKA Ozone. ([ce']O_3[/ce]) But your right oxygen is an oxidant, it reccieves electrons from other elements / compounds and in the process reduces its self by gaining the electrons If you could make this work commercially then a lot of people may be interested but it would be no small challange! Cheers, Ryan Jones

Looks like this stuff is really hard to keep in its pure form then. Is it best just to buy this stuff as you need it? Cheers, Ryan Jones

That big? Thats an impressive length. If you take all those chromosomes from every cell in every person, plant etc. you would have a huge chain! Cheers, Ryan Jones

Ah, right I see. Those defects over a long length can cause the structure to break down - seems logical So there is a limit imposed by nature (Defects) but the actual length of the chain would otherwise have no limits? Right - got it! Thanks all Cheers, Ryan Jones

this website explains it well. Read there and see if it helps you at all Cheers, Ryan Jones

It depends on how you look at it - these bonds give it its cohesive and solant properties. At what level are you stddying? Have a look at this and also this - its the first place I look for chemistry type answers like these Cheers, Ryan Jones

Heat kills yeast by denaturing its enzymes thus renderind it useless. Also a high or low Ph would do the same thing If you could engineer an anti-body to attack and kill the yeast cells that would certainly stop them from working but thats probably way beond anything you could do for an experiment. Cheers, Ryan Jones

Looks like you can't - apparently its reacts with Oxygen. Source: http://81.207.88.128/science/chem/elem/elements/Cu/index.html Cheers, Ryan Jones

Yes it does... it is used to track planets orbits accuratly, its used are unlimited - jest because you think it does have no efect on everything does not mmean that it does not have any use - this should probably be moved to the Metaphysics section... I'm no expert on relativity, but there are a few people on this forum who could be considered to be - maybe they will be able to give you some practical applications. Cheers, Ryan Jones

Just tested in Firefox 1.5 Beta 2 and it works fine, User Agent String below: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.8b5) Gecko/20051012 Firefox/1.4.1 - Build ID: 2005101209 Cheers, Ryan Jones

Unless you have sufficient ocygen for the higher octane fule to burn in then you would get a lot of messy stuff... if you could find a way to readily supply the oxygen to the pistons then it should give you a boost. You'd also have to o some testing to find the optimim oxygen to air ratio - if you cna then you can patent it and sell it to the car manufacturers Why do you think they don't use really high octane fules in cars? It sprobably ebcause it would ignire too easily though there jsut be ways to do this also. Fild some way to denature the fule intil it comes into the cylinder then just before the compression activate it with some kind of catalyst and then add the pure Oxygen and then that should work good - maybe this would also be better in the Engineering section? Cheers, Ryan Jones

Yup, I agree. We'd have a hard time digesting things if it were not for these little proteins... its also why extreme heat and cold are so dangerous to humans. Speaking from my first point ther eit is a common missconception that its the acid (Hydrochloric) in your stomach that breaks down the food (Mostly from younger kids) when infact its used as a primer for the hydrolytic(sp?) enzymes which are secreted in an unactive state and also to kill any bad bacteria or anyhting else that may try to stray into the wrong place. Note: I am not saying that you people did not know that but just thought I'd point it out incase there any younger readers here too Cheers, Ryan Jones
