You're asking about the reaction between silver nitrate (AgNO₃) and potassium sulfate (K₂SO₄). This reaction results in a double displacement reaction, where the cations and anions of the reactants switch places.

Here's how the reaction proceeds:

1. Identify the reactants and products:

* Reactants: AgNO₃ (silver nitrate) and K₂SO₄ (potassium sulfate)

* Products: Ag₂SO₄ (silver sulfate) and KNO₃ (potassium nitrate)

2. Write the balanced chemical equation:

2AgNO₃ (aq) + K₂SO₄ (aq) → Ag₂SO₄ (s) + 2KNO₃ (aq)

Explanation:

* Silver sulfate (Ag₂SO₄) is insoluble in water and forms a precipitate (solid). This is why we see a solid forming in the reaction mixture.

* Potassium nitrate (KNO₃) is soluble in water and remains dissolved.

Therefore, the molecular formulas for the products of the reaction are Ag₂SO₄ and KNO₃.
