I was wondering how C02 is collected? (for things like fire extinguishers, aquariums, etc)
Can it be taken directly from the air and "bottled"?
I'd assume it's by a large scale chemical reaction. Almost any metallic carbonate and acid will react to form CO2 and other chemicals. The CO2 wiki (http://en.wikipedia.org/wiki/Carbon_dioxide#Synthesis_and_chemistry) has a pretty good section on it.

It's produced as a by product from other chemical processing.

I think I remember hearing it is produced in large scale by the combustion of methane, then seperated by fractional distillation.
they get a heap of people to breath into bags and they bottle it.....hehe couldn't resist

Then please explain how CPR works?
Seriously your exhaled breath is not pure CO2.

If exhaled breath was pure CO2 then re-breathers used for scuba diving wouldn't work which basically takes CO2 out and diverts leftover O2 to be inhaled again.

I think the "hehe couldn't resist" part meant he was joking. It was a joke. You laugh at it.:dance2:
