Which is the correct net ionic equation for the reaction of aqueous ammonia with nitric acid? Which is the correct net ionic equ
Svet_ta [14]

Answer:

The last option:

  • NH₃ (aq) +  H⁺ (aq)  →  NH₄⁺ (aq)

Explanation:

1) Word equation

  • Aqueous ammonia + nitric acid → aqueous ammonium nitrate

2) Chemical (molecular) equation

  • NH₃ (aq) + HNO₃ (aq)  → NH₄ NO₃

3) Ionization reactions

Write the dissociation of the soluble ionic compounds:

  • HNO₃ → H⁺ + NO₃⁻
  • NH₄ NO₃ → NH₄⁺ + NO₃⁻

4) Total ionic equation:

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

5) Net ionic equation

You must cancel the spectator ions, which are those ions that are repeated in both reactant and product sides, i.e. NO₃⁻. They are name spectator because they do not participate (change) during the reaction.

  • NH₃ (aq) +  H⁺ (aq)  →  NH₄⁺ (aq)

And that is the last choice of the list.

What is meant by a chemical bond? why do atoms form bonds with each other? why do some element esist as molecules in nature inst
Alex Ar [27]
It is the attraction between two atoms resulting from a redistribution of their outer electrons. Atoms form chemical bonds in order to make their outer electron shells more stable. Some resist due to some being very big and electronegative
