Aquesous ammonia, help!

I don't know if this is a stupid question but if a question says state the formula of aqueous ammonia, what would you write ?
Do you write NH3(aq), NH4OH or NH3 + H20 ?? Or is it completely different ?
I am doing the new chemistry A level (OCR A)

Thankyou xD
I would write it NH3(aq)
I'm doing the old spec but I assume it wouldn't change

I don't think you'd ever just be asked to write the formula of aqueous ammonia.

Maybe as part of an balanced equation, in which case, you'd write whichever formula supported the property you were trying to demonstrate...

e.g. if you wanted to show NH3 acting as an alkali, you'd write NH4OH, or for ligand exchange (A-level topic, i.e. not AS) you'd write NH3.

okay so as part of the balanced equation would I write
NH3(aq) +H20-> NH4 + OH

Only if you show the charges on the NH4+ and OH-

You would just write NH3 but since its told you thats its aqeous, its probabl expecting state symbols so just write NH3(aq).
