    Precipitate???

    Balanced "molecular" equation

    3NaF(aq) + Fe(NO3)3(aq) --> FeF3(s) + 3NaNO3(aq) 

    Net ionic equation

    Fe^3+ + 3F- --> FeF3(s)

    Since FeF3 is "slightly soluble", the concentrations of iron(III) ion and fluoride ion must be fairly high in order to get a precipitate.

    1.

    NaF(aq) + Fe(NO3)3(aq) → FeF3(s) + NaNO3(aq)

    2.  The precipitate is the product marked "s"olid.

    Fe{3+}(aq) + 3 F{-}(aq) → FeF3(s)
