    anyway its easy to work it out i have got half of it in the last 5 or so minutes you should listen in class then you would understand it, this may sound a bit mean but trust me listen in class and if you dont understand it ask a teacher

    whats wrong with you doing your own homework you will never learn how to understand it if you dont do it yourself
  6. why what does lithium nitrate look like
  7. i just thought do you also collect things which are not on the periodic table eg potassium nitrate ect
  8. still i have found a graham condenser on ebay.com which comes to £28 including delivery insurance plus the condenser
  9. yes it was from united nuclear, i was going to order it but i read they do not ship international any more i only thought that was for chemicals but its not its for every thing
  10. would you say £25 is cheap for a graham condenser because i am really tempted to buy one because i think that is cheap
  11. would any old paint shop sell aluminium powder or would it be a specialist
  12. plus nitrocellulose is one of the more safer nitrations
  13. thank you for your concern but i have made it before and the very most important things are dont let it get over 70C during nitration make sure you neutralise it and dont make large quantities and i think .5g isnt exactly large quantities is it. 5ml for every .5g thats what i would use
  14. i know all the procedures 2.5ml/nitric acid 2.5ml/sulphuric acid add .5 cellulose let it nitrate for 5minutes then boil it in sodium bicarbonate solution and rinse with distilled water untill it tests for neutral etc if you make large quantities it may result in a run away as well thats way if you were to make it make it in small quantites, and its nice to see you yt not heard from you in a while
  15. yes that is what i thought, i just needed somebody to clarify it
  16. this is just a thought if you were to make nitrocellulose could you reuse the 50/50 sulphuric acid/nitric acid mix after you all ready nitrated some .5g cellulose to make some more nitrocellulose
  17. or you stand to close because they shoot out molten iron at you
  18. it is a fact that it is the raven or crow can not remember which one that is the smartest bird of all it is able to make tools out of sticks or wire by bending them and using the wire to extract food from small holes they have also been know to drop nuts which they can not get into on the roads in line of cars tires untill one runs over the nut and crush's the shell so it can eat the nut, as well as mimic, and some have also learnt to pull bin bag liners up from bins by grabing with there beak pulling up and trapping it under there claws untill they can reach the food in the bins. now didnt i say they were cleaver
  19. well why would he be blowing him self up even if it was plasticy aluminium as he said
  20. why what do you want to make with it anyway
  21. and aluminum can only has a thin layer of tin on its much pure then using aluminium foil like you sujested and if you want to make thermite an aluminum can works two reasons i know one there is a program called rough science where in one of the episodes he used an aluminium can to make thermite and two i have made it my self from an aluminium can
  22. aluminium foil isnt pure aluminium it is'nt even close if you burn aluminium foil you will see a plastic covering aluminium foil isnt any real use so use an aluminum can, if you look on the side it will have a triangle with the words alu in it to confirm its an aluminium can
  23. it was most probably some other chemical on it used in a previous experiment and not washed propley at my college that happend quit often and so we made sure we washed the appiratus when we came to use it other wise the experiments would be ruined eg titrations
  24. and i am very supprised your teacher did not no this maybe he did not want to tell you.
  25. because it may have not been concentrated enough to do it the first time
