The balanced symbol equation for burning sulfur in oxygen to make sulfur dioxide is:

S(s) + O₂(g) → SO₂(g)

Here's what each part represents:

* S(s): Sulfur in its solid state.

* O₂(g): Oxygen gas.

* SO₂(g): Sulfur dioxide gas.

This equation shows that one atom of sulfur reacts with one molecule of oxygen to produce one molecule of sulfur dioxide.
