Answer:
The reaction NH3(aq) + HNO3(aq) → NH4NO3(aq) is an acid-base reaction. In an acid-base reaction, an acid and a base react to form a salt and water. In this reaction, the acid is nitric acid (HNO3) and the base is ammonia (NH3). The salt that is formed is ammonium nitrate (NH4NO3).
The other choices are not correct. A precipitation reaction is a reaction in which a solid precipitate forms from a solution. A redox reaction is a reaction in which electrons are transferred between atoms or molecules. A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances.
