You're describing a molecule with one sulfur (S) atom and four oxygen (O) atoms, which is likely sulfur dioxide (SO₂) or sulfur trioxide (SO₃).

Here's why:

* Sulfur dioxide (SO₂) has one sulfur atom and two oxygen atoms.

* Sulfur trioxide (SO₃) has one sulfur atom and three oxygen atoms.

To figure out what the products of a reaction with this reactant would be, we need more information about the reaction itself.

Here's what you need to know:

* What is the other reactant? The type of reaction depends on what the sulfur oxide reacts with.

* What are the conditions of the reaction? Temperature, pressure, and the presence of catalysts all influence the products.

For example:

* SO₂ reacts with water (H₂O) to form sulfurous acid (H₂SO₃).

* SO₃ reacts with water to form sulfuric acid (H₂SO₄).

Let me know if you can provide more context about the reaction, and I can give you a more specific answer about the products!
