  1. what like chemo theropy?
  2. im not making chloroform again ^^ not after i nearly knocked myself out. it smells nice tbh ^^
  3. DCM has been banned for use in paint strippers here in the UK (an the EU) so that opition is out of the window^^
  4. mainly because i dont have much money to buy DCM ^^ acetone and white spirit are cheap and easier to obtain ^^ i know i can get DCM on ebay and i might do that next time i get paid ^^ but atm im running a mini trial with both white spirit and acetone using 125m of both solvent to see what woul happen
  5. have you tried ebay?
  6. will it be possible to extract this from black pepper using white spirit or acetone as i dont realy want to be using DCM... sorry for the spelling mistake ^^ its ment to be piperine
  7. if you press two peices of ice together they stick...
  8. i saw a video on youtube about the making of hydrobromic acid, the guy used potassium bromide and sulphuric acid the set up was a beaker and over head stirrer and then a basic still. to me this seemed a bit ott because the product would require to be sepurated from the residual H2SO4 by using simple displacement chemistry one can make it using hydrochloric acid, this in theory should produce a more pure sample for the HBr can be boiled off and passed through distilled water to produce the acid. equation: KBr(aq) + HCl(aq) --> KCl(aq) + HBr(aq) instead of: KBr(aq) + H2SO4(aq) --> KSO4H + HBr
  9. in simple terms. the HNO2 forms ions of gold but in an equalibrilum so it does not dissolve, the HCl then bonds to the gold ions to form AuCl3 and this can not reattach to the gold, then the HNO2 ionises more gold and the process continues untill the gold is dissolved
  10. faraday cages would protect agaist EMPs, so if you have an iphone and are worried about EMPs stick it into your budgees cage at night...
  11. death is not a direct result, it is abit like major flooding, those who survive the wall of water will have to contend with diseases... my point is that an EMP might indirectly cause death but it woud cause chaos and panic over vapourizing hundreds of civies
  12. yes but cyber attacks do not cause death, and nethier do non nuclear EMPs
  13. EMPs occure as a side effect of nukes, and the EMP its self is not very destructive (unless you are on life support or in a plane) so it would be caled a weapon of mass disruption, much like how biological and chemical/radiological (dirty bombs) they don't cause damage by destroying a vast area in one area nor can they change the landscape (destroy mountains) unlike the nuke blast that emmits the EMP. so a weaponized EMP would be more of an inconveanience than a threat.
  14. that is to be understood ^^
  15. store it a glass reagent bottle... surely glass is more inert than HDPE to acid corrosion
