Seawater found to be seeping up through the canyon floor is why

scientists think Grand Canyon was once covered by an ocean.

Grand cayon is located in Arizona, United States and comprises of a lot of

fossil records and rocks which makes it one of the best sites for geological

study.

The Grand cayon was found to be seeping through its floor which made

scientists think it was once covered by an ocean years ago.

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.
