Correct Answer: Option (A)
H₂S : SO₂ = 2:2 and,
O₂: H₂O = 3:2
Explanation:
The mole ratio is the ratio of coefficients of the compounds involved in the reaction. Reactants, as on the left hand side of the chemical reaction which reach to form new products.
In the given reaction,
2H₂S + 3O₂ ⇒ 2SO₂ + 2H₂O
The reactants are : H₂S (hydrogen sulphide) & O₂ (oxygen)
The products are : SO₂ (sulphur dioxide) & H₂O (water)
Therefore correct option is
H₂S : SO₂ = 2:2 and,
O₂: H₂O = 3:2
