Does a reaction occur when an aqueous solution of calcium iodide and sodium sulfate are combined. if a reaction does occur write the net ionic equation.

Yes. Ca²⁺(aq) + SO₄²⁻(aq) ⟶ CaSO₄(s)

Step-by-step explanation:

The possible reaction is

CaI₂ + Na₂SO₄ ⟶ CaSO₄ + 2NaI

To predict a reaction, you must know the solubility rules.

The important ones for this question are

Molecular equation

CaI₂(aq) + Na₂SO₄(aq) ⟶ CaSO₄(s) + 2NaI(aq)

Ionic equation

Ca²⁺(aq) + 2I⁻(aq) + 2Na²⁺(aq) + SO₄²⁻(aq) ⟶ CaSO₄(s) + 2Na⁺(aq) + 2I⁻(aq)

Net ionic equation

Cancel all ions that appear on both sides of the reaction arrow (underlined).

Ca²⁺(aq) + 2I⁻(aq) + 2Na²⁺(aq) + SO₄²⁻(aq) ⟶ CaSO₄(s) + 2Na⁺(aq) + 2I⁻(aq)

The net ionic equation is

Ca²⁺(aq) + SO₄²⁻(aq) ⟶ CaSO₄(s)

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
