    CO2 or carbon dioxide

    Do you always read this as "carbon dioxide" or "See Oh Two" as well? I think the same goes for H20 meaning water.
    GO2-12)A flight between London Heathrow and New York's John F Kennedy airport creates around 1.35 tons of CO2 per passenger - more than one-third of the yearly emissions of an average person worldwide.

    You can use either and be understood. But if it's written CO2, then I'd read it that way.

    Re: CO2 or carbon dioxide

    I would read it as "see-oh-two" as well, especially if reading it aloud. If, however, I was trying to explaining the concept to someone who might not know the chemical elements, I would probably call it carbon dioxide. We read and see CO2 much more frequently than H2O, unless we are in a scientific environment. CO2 has only become relatively well-known due to environmental/green issues.
    Remember - correct capitalisation, punctuation and spacing make posts much easier to read.

    That's right. It's quite OK in English to say we breathe out CO2, but it's not natural to say we drink H20.

    Re: CO2 or carbon dioxide

    I think most people are savvy enough to understand what "H2O" is. (It's what you mix with your C2H5OH.)

    I mix soft drink (probably what you'd call pop or soda) with my C2H5OH, unless I'm disinfecting a wound with it.

    Yeah, but that's just fizzy sugar-water.

    In which case, you can also use C3H7OH.

    Re: CO2 or carbon dioxide

    Reminds me of the epitaph:

    "Alas, poor Fred, he is no more
    For what he thought was H2O was H2SO4!"


    R21

    PS: H2SO4 = Sulphuric acid.

    To say nothing of the K9P joke (low quality of water - you can roll your own )
