    D. NH4 + (aq) + NO3? (aq) - -> NH4NO3 (aq).

    Explanation:

    Reaction between ammonia and Nitric acid is a acid and base reaction where ammonia is the base while Nitric acid is the acid.

    NH3 (aq) + HNO3 (aq) - -> NH4NO3 (aq)

    Ionic equation:

    NH3 (aq) + H + (aq) - -> NH4 + (aq)

    Net ionic equation

    NH4 + (aq) + NO3 (aq) - -> NH4NO3 (aq)

    The correct answer is

    e. NH3 (aq) + H + (aq) - -> NH4 + (aq)

    Explanation:

    To solve this, we write out the indidual ionization reation for aqueous ammonia and nitric acid thus

    For aqueous ammonia we have

    NH₃ (aq) + H₂O (l) ↔ NH₄⁺ (aq) + OH⁻ (aq)

    Aqueous ammonia is a weak base and therefore undergoes partial ionization hence the reversible reaction sign

    As the level of ionization will not be more than 5% OH⁻ cannot represebt the weak base

    For nitric acid we have

    HNO₃ (aq) → H⁺ (aq) + NO₃⁻ (aq)

    a strong acid like nitric acid undergoes conplete ionization in the solution

    The total equation is NH₃ (aq) + HNO₃ (aq) → NH₄NO₃ (aq)

    The sum of the ionic equation is

    NH₃ (aq) + H⁺ (aq) + NO₃⁻ (aq) → NH₄⁺ (aq) + NO₃⁻ (aq)

    The ionic equation is

    NH₃ (aq) + H⁺ (aq) → NH₄⁺ (aq)
