Combustion of Ethanol: Is ethanol a liquid or gas here?

Apparently from C1 to C5 Hydrocarbons are all gases at room temperature. So does that mean when i write the equation of combustion of ethanol it would be a gas?

 

[Mr_Kap]

anyone?

When they're referring to hydrocarbons in this context I believe they're referring to alkanes and alkenes and that is why for that bromine water experiment we use cycloalkenes and cylcloalkanes; they are liquid at room temperature and more stable than their linear counterparts

It's aqueous

Ethanol is not a hydrocarbon. It is liquid at room temperature

The combustion of ethanol is assumed to occur in cars (i.e. as a fuel blend)
Therefore it is assumed to be aq, but I dont believe you will be penalised if you write (l)

wat

 

[Drsoccerball]

Im pretty sure its liquid

That's only assuming it's pure ethanol

It's similar to how acids can be liquid or aqueous depending on their concentration

You still put the state as liquid, otherwise the marker is going to think your using aqueous ethanol mixture as a fuel.

Um. Yeh. Do I just put C2H5OH(laq) then?

You'll get a mark deducted for putting (aq) in a combustion reaction if it asks for it. Or 2 if it's worth 2 marks.

Oops my bad

I didn't read it for combustion

Yeah for combustion it's definitely liquid but for other reactions such as hydration of ethylene you can put it as aqueous

 

[Mr_Kap]

alright thx

You need to react steam with ethene in a hydration reaction, but the boiling point of ethanol is lower than water, so it should be in a gaseous state aswell.
