First, identify the chemical formula for the chemical mentioned in the problem.
Hydrogen sulfide: H₂S
Air (Oxygen): O₂
Sulfur dioxide: SO₂
Water vapor: H₂O
Next, identify the reactants and the products as described.
Reactants: H₂S and O₂
Products: SO₂ and H₂O
The reaction is written as
Reactants --> Products
Therefore, the unbalanced chemical reaction is:
H₂S + O₂ --> SO₂ + H₂O
