The balanced chemical equation for the reaction of carbon disulfide (CS₂) with oxygen gas (O₂) to produce carbon dioxide (CO₂) and sulfur dioxide (SO₂) is:

CS₂ + 3O₂ → CO₂ + 2SO₂

Here's a breakdown:

* CS₂: Carbon disulfide, the reactant.

* 3O₂: Oxygen gas, the reactant. Notice the coefficient of 3 is needed to balance the oxygen atoms on both sides.

* CO₂: Carbon dioxide, the product.

* 2SO₂: Sulfur dioxide, the product. Notice the coefficient of 2 is needed to balance the sulfur atoms on both sides.

This equation demonstrates the conservation of mass, where the same number of atoms of each element are present on both the reactant and product sides.
