Based on listed oxidation states which formulas would most likely result when sulfur and oxygen combine to form a compound?

SO₂ (Sulphur(iv)oxide)

Explanation:

Oxidation: Oxidation is the process involving a loss in electron, it can also mean the addition of oxygen to a substance during chemical reaction. It can also mean removal of hydrogen from a substance during chemical reaction. it can also mean addition of electropositive element and removal of electronegative element from a substance during chemical  reaction.

Oxidation Number: The oxidation number of an element in any particular molecule or ion is defined as the electrical charge.

Sulphur have variable oxidation states. And the oxidation number of surphur

is -2, -4 or -6, and the oxidation number of oxygen is -2.

Therefore when sulphur react with oxygen, the most likely results is sulphur(iv)oxide. (SO₂).

c) should be the answer.
