  1. Making a mountain out of molehill here. It is a simple problem. Deserving a simple solution. I'm using ratios between sides and angles. They are both related. Sure it trig, but you don't have to use a calc to solve this problem.

     

    Fswd: He brought the "God" topic up.

     

    That is exactly what the tan function does, but different, as you cant divide metres by angles cuz the goniometric functions need to be fed dimentionless figures to get angles, which you get by for example divide metres on eachother.

     

    Oh well i'm using tan just in a wrong form.

     

    You arent using it at all.

  2. actualy i've been thinking about this...but hopefully i could find somebody to give me a solid explanation.. because I did know organic compund is composed of many such as phenol, alcohols, hydrocarbon(easy word,element that contain carbon ) and etc... but my Organic Chemistry practical questioning us like such..:confused: I've try to pull in all organic compound so that a derivation of a symbolized equation will be happen but it seems....huh!:-( please anyone....

     

    Oxidation of an organic compound (like burning) tries to put every atom in its highest oxidational state. We can say when something like methane, (C -4, H+1) is burned, we get CO2 (C +4, O -2) and H2O (H +1, O -2).

     

    When we burn chloroform, CHCl3 (which doesn't burn so good as the C is already +3), you could still say that the Cl can be oxidized up to +7. It yields ClO4-.

     

    What i mean with the + and - a number, i give the oxidation state of that particular atom. I know this analogy is wrong when looking at covalent bonds, but it is a good way to explain these things.

  3. well the Vid would be more trouble than it`s worth the files even for 10 seconds always end up Massive!, as for the design, I can give you my parts list and explain how and why they go together, sure :)

     

    Thats why they invented codecs :doh:

  4. It's a bit "old school" but that reaction works quite well. The other dominant product is sulphur vapour but I don't think that would blacken PbCl2.

    I don't see why it's not the conditions I described; I passed H2S over moist PbCl2 and it went black.

    In principle all reactions are reversible so while it's fair to say that the reaction would usually give lead chloride and a nasty smell it can be driven the other way.

     

    It actually could:

     

    S + 2e- --> S2-

    2Cl- --> Cl2 + 2e-

     

    And no, not all reactions are reversible: can you put the same CO2 and H2 back together into C8H18 and oxygen?
