Please classify the following substances into compounds or mixtures?
a) air
b) water vapour
c) carbon monoxide
Answer:
Air is a mixture as air is a combination of all kind of gases such as oxygen, carbon dioxide, nitrogen and so on.
Water vapour and carbon monoxide is a compound.
Water vapour can be collected and has it changes its phase to liquid state. After that, you can separate oxygen and hydrogen gases through electrolysis.
As for the separation technique for the others, I couldn't think of a better one than what Cemre Tas has suggested.
perhaps an oxidation machine for the air, to seperate the oxygen, nitrogen, and the misc elements. However its hard to contain the seperate items.
Collect the water vapor into a liquid state, then throw some metal KN03 into the mixture and allow the pottasium to seperate it into oxygen, the hydrogen will be burned off.
Carbon monoxide is to push it into a space where air cant escape, then open the top of the space to allow the air to leave, the C02 wont because its denser then air and will remain at the bottom.
only a is a mixture, the other two are compounds.
to separate air into it´s components all you have to do ( and this IS how liquid oxygen and nitrogen are produced) is to distill it (under pressure and low temp, of course)
