TheLonelyIsland:
also, plz, when a gas is collected from a reaction, why does it have to pass through a liquid, and then finally be collected, and what role does the type of a liquid play in all this? Help, plz, don`t get it...
:)
TheLonelyIsland:
Anyone?... Pretty please?

Er, I don't really know the exact reason but a gas is collected over because it is insoluble in water and it is more convenient. Sorry I couldn't help you much. i would be waiting for an accurate answer too. :-[
TheLonelyIsland:
Thanks anyway! You know what I mean though, right? For example in catalytic cracking, when an alkene is collected, the delivery tube first passes through water... why? Why not just downward delivery? That`s just an example though, there are other reactions involving another liquid, not water...
Anyway, good luck!
