yes sugar does produce water when burned so charcoal would be better

i see you are talking about a controlled heat experiment one eg where zinc powder reacts with water to generate a exothermic reaction which is not capable of welding steel

ahh yes do ignore my post i just quickly scanned through the older ones and came across the word thermite then you asking about aluminium which goes with thermite and so i thought you wanted a thermite reaction sorry about that

yes for a thermite reaction you can just use iron oxide(rust) and aluminium 75% rust 25% aluminium, but i must warn you must not mess around with thermite it throws molten iron around once ignited and can reach temperatures of upto 3000c and the only time magnesium is used is in the form of magnesium strip which is used to ignite the mixture but you could just use a hand held turbo lighter tie it to a long stick and turn the lighter on it will ignite the mixture at a safe distance

its the circuits which are made out of silicon

how can you dry KNO3 when it has become damp

LOL that was quite witty

which companys make zinc/czrbon batterys so i know which ones to look for

so how good is lead nitrate as an oxidising agent, if its ok what are the ratios of nitric acid and lead to make lead nitrate

LOL same here except i lernt German

i have heard of that before and i read some where that they might even start to use it in airbags because it is so fast at releasing gasses which is good for the use in a airbag

do all local tire shop's use lead because there is one quite close to me, well its a garage but they also deal in tires so if i ask would they give me some, also what can lead nitrate be used for how good is it as an oxidising agent

i used to have the old black box but the blue bin is new we have had it for about 1-2 months now and we have the standard wheel bin collection every week but that is not for recycling, oh yes we also get a box for recycling bottles so that is something else i recycle

now in britain they give everyone a big blue bin to recycle paper, so yes i recycle a bit

they can do that now anyway carnt they because they put a chemical in which changes colour when somebody pees,and also did you know the reason why americans do not spell words the correct way is because they had to simplify words for immigrants who were not able to pronounce them correctly arnt they nobel:)
