2h2s + 3o2 2so2 + 2h2o which option gives the correct mole ratios? h2s: so2 = 2: 2 and o2: h2o = 3: 2 h2s: so2 = 2: 3 and o2: h2o = 3: 2 h2s: so2 = 4: 4 and o2: h2o = 5: 4 h2s: so2 = 4: 6 and o2: h2o = 4: 4

Correct 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
