    I got D,D,A,D.

    The reason why I say D is because the reaction to form Ammonium Nitrate is a neutralisation reaction...

    NH3 + HNO3 --> NH4NO3,

    which turns Ammonia into Ammonium Nitrate!

    D - because an acid dissociates to form a Hydrogen ion which is positive and an alkali dissociates to form a hydroxide which is negative, so that forms the water

    D - acid + base --> salt + water, so you need to work out what you can have a base with etc and an acid

    A - you need a hydroxide for the alkali and sodium is a metal

    D - the sulphate comes from the sulphuric acid

    But i was thinking that this reaction is not in the form:

    H+ (aq) + OH- (aq) --> H2 O(l)
