    Hair extensions

    I've had a hundred people tell me not to get weaves and yes, they aren't too good for your hair. BUT what I do is just get them for special occasions and then take them out straight away and then keep the hair so it stays in tact, then pay the hairdressers just to put them back in. Bankstown...

    solubility of gases

    I realise that the solubility of gases increases with ocean depth due to increased pressure and decreased temperature, but what about at the light zone and in between?

    long response q for 2009 HSC

    I hope the extended response will be on Galvani, Volta etc that'll be easy as! I'll die if they put something bout water quality or anything from acidic environment lol If they did put anything from the acids module as an extended response what do you reckon it would be?

    States of ethanol and glucose in fermentation

    On that note, do you think that if we get a state wrong in an equation we wouldn't get the mark?

    Steel composition.. quick question

    Thanks heaps for the quick reply! =) That's what I thought, but I just read over a prac (the first one on shipwrecks) and it said that the steel corroded more than the iron. If iron contains more carbon than steel, why did the steel corrode quicker? It was in the Success One book.

    Steel composition.. quick question

    Can someone quickly tell me the connection between the amount of carbon in a steel and the rate at which it corrodes.. I'm guessing it's more carbon -> more cathodic sites -> corrodes quicker Is that right??

    Ethanol as a fuel

    Ok wait I do get what you're saying.. so it's sorta assumed that all of the CO2 released during fermentation and combustion of ethanol is going to be absorbed during photosynthesis

    Ethanol as a fuel

    Yeah theoretically it's right but it actually doesn't take into account the carbon dioxide that is used in photosynthesis to produce the glucose 6CO2 + 6H2O -> C6H12O6 + 6O2 so there is actually more carbon dioxide used than is produced

    Ethanol as a fuel

    I was just wondering, other than that it is renewable and undergoes complete combustion, what is another advantage of using ethanol as a fuel? I was going to use 'carbon neutral' but I've just been told that it's incorrect. Any help would be much appreciated =) Thanks
