The chemical reaction is:
C6H5COOH + NH4OH = C6H5COONH4 + H2O
(NH4)2CO3 + 2HCl -> H2O + CO2 + 2NH4Cl
HNO3 + NH3 =NH4NO3 is not a precipitation reaction, ALL(NO3-) nitrates are soluble even in water.
This is an oxidation reaction of N from -3 (in NH3) to +2 (in NO) oxidation value. 4 NH3 + 5 O2 --> 6 H2O + 4 NO
Ammonia Reaction Isn't SYNTHESIS REACTION?
It is an acid-base reaction and also a synthesis reaction.
3N2H4 --> 4NH3 + N2 is the correctly balanced equation.

Decomposition
Ammonia Reaction Isn't SYNTHESIS REACTION?
This is an acid-base reaction or proton exchange, but there are many more reaction possibillities depending of Cu2+, OH- and NH3 concentration
There are 15 moles of ammonia sulfate in the reaction of 30.0 mol of NH3. This goes from the formula 2 NH3 H2so take away (NH4)2So4.

As you have it written NH3 donates a proton to the solution and this hydrogen ion is picked up by PH3 to make PH4; so NH3 is the acid here. ( though this reaction seems odd to me )
You could say ammonium hydroxide, but that is not quite correct in solution. NH3(aq) is sometimes used, but this is the equilibrium reaction. NH3 + H2O <<->> NH4(+) + OH(-)
This would be a synthesis reaction. General formula A + B yields AB.
