  1. I formatted my PC due to a virus problem and re-installed windows. I however only later realised that I don’t have the drivers CD that comes with the PC. I have an AMD CPU and a NVIDIA graphics card. I was able to download (from another PC) the drivers for the Graphics card because I knew the make and model. I went to the AMD website and downloaded several driver packs but none of them worked all giving me the error code “No AMD components Found”.


    Can anyone please help me? I need the drivers for the motherboard etc. Is there a program that can analyse what drivers I need? Thanx


    P.s I really don’t know what to do now. At the moment my Ethernet port doesn’t work so no internet at that Pc. However I do (obviously) have access to the net!!

  2. This is quite interesting !


    How does O3 to decompose.


    Does it decompose Spontaneously ?

    If so what would its half life be ?

    What catalist would promote decomposition ?


    And ...


    When you say it filters UV ...


    Does 02 not just absorb some of the UV's energy and because of that splits to form two singlet O's that then combine with O2 to form O3 ???


    O2 + 2 O2 + UV -> 2 O3 + (no UV )or(a wave of less energy eg light)???



  3. You could make (Mn2O7) which when decomposes produces two O3 molecules and Manganese (ii) Oxide.

    One can make Mn2O7 by reacting a VERY SMALL (50 mg or so) amount of Potassium Permanganate with Sulphuric acid which will produce a green oily substance (Mn2O7). Im not sure how you would get it to decompose without causing an explosion but this is how I would go about producing O3.

    Before you even consider this there are several safety concerns and technical details that you may want to consider. Just check out the link before you try anything.



  4. This thread has been dead for years and now but anyway.


    When i need Al powder and it isn't critical that it be very fine (or pure for that matter) then i just take Aluminium foil and put it in a blender. If you run the blender long enough it makes it fine enough to make thermite with ;) and you get showers of bright white burning pices of Al what ever you use it in. :)

  5. CO2 can supply oxygen to elements and compounds that are stronger reducers than it such as magnesium , aluminium , Potassium etc. The element or compound then takes (reduces) the O2 part Of CO2 for oxidation leaving elemental Carbon.

  6. I would strongly sugest that you dont try anything in that book before consulting someone who has had some chemistry expirience or the forum. Wile the book is nice to read through to get ideas or inspiration from not all the articles are safe or acurate .


    Sory my last post is quite ambiguous :doh: i was refering to the "anarchists cook book"

  7. No not all the powder disolved (it could just be that the acid lost some acidity though)! I gree that it may be a aloy of copper but i dought it contains any silver (baught it for quite cheep).


    It was slightly affected by a strong magnet (when i moved the magnet close i saw the particles moving a bit) but not enough for the powder to "slick" to the magnet.


    What chloride soln should i add to the nitric HNO3 metal mix (chloride that i got from the HCl and metal mix)?



  8. It is a grey/silver metalic powder.

    I didnt observe any reaction between it and a strong NaOH soln after 20 min.

    It has a density of 3.08 g/ml


    Something to consider, it might be an aloy.


    P.s my density might be slightly off (i used a scale that only has one decimal).


  9. I was walking ... ok you dont need to know the details.


    I have a jar of metalic powder that i found in a garage. It was used to make reflective paint so i asumed Al ... So to test my theory i put a pinch into HCl but nothing happened :confused: so now i am lead to believe that it is not Al. I tested it with a magnet. Its not magnetic. It is grey in colour and is quite heavy (i will work out its density and post it later)


    Any suggestions as to how i can find out what it is ???

    Much appreciated
