The Attempt at a Solution
I know E is definitely wrong because its organic so its insoluble in water. Water is polar so polar gases should be soluble in it, B and D are polar. Also carbon dioxide should be soluble in water because CO2 + H2O -> H2CO3. This gives me 3 gases that will be be able to be collected over water but there should only be one.
Thanks!
