    2NH3 - Gas Phase

    2 NaCl - Solid Phase

    2KNO3+PBI2 - Aqueous Phase

    Explanation:

    2NH3 is ammonia gas which is colorless and has a bad pungent smell.

    NaCl is salt. It has crystalline structure and can exhibit both aqueous or a liquid phase. Since there is no H2O molecule in the formula of NaCl, hence it is not aqueous. It is not liquid as well because liquid NaCl is represented as NaCl (l) while aqueous NaCl is represented as NaCl (aq).

    The reaction 2KNO3+PBI2 will take place in aqueous phase and hence these two exists in aqueous phase
