write net ionic equations for the reaction, if any, that occurs when aqueous solutions of the following are mixed. a. ammonium s
sertanlavr [38]

Answer:

SO₄²⁻(aq) + Ba²⁺(aq) ⇒ BaSO₄(s)

Explanation:

Let's consider the molecular equation that occurs when aqueous solutions of ammonium sulfate and barium nitrate are mixed.

(NH₄)₂SO₄(aq) + Ba(NO₃)₂(aq) ⇒ BaSO₄(s) + 2 NH₄NO₃(aq)

The complete ionic equation includes all the ions and insoluble species.

2 NH₄⁺(aq) + SO₄²⁻(aq) + Ba²⁺(aq) + 2 NO₃⁻(aq) ⇒ BaSO₄(s) + 2 NH₄⁺(aq) + 2 NO₃⁻(aq)

The net ionic equation includes only the ions that participate in the reaction and the insoluble species.

SO₄²⁻(aq) + Ba²⁺(aq) ⇒ BaSO₄(s)
