Which statement correctly explains why H2S is a stronger acid than water?(1 point)

Responses

Sulfur (S) has a larger atomic size than oxygen (O), so H2S is a more stable, weaker base than H2O.
Sulfur (S) has a larger atomic size than oxygen (O), so H 2 S is a more stable, weaker base than H 2 O.

The correct statement that explains why H2S is a stronger acid than water is:

Sulfur (S) has a larger atomic size than oxygen (O), so H2S is a more stable, stronger acid than H2O.

This is because the larger atomic size of sulfur allows for the H-S bond to be more easily broken, which contributes to the acidity of H2S compared to H2O. In addition, the conjugate base HS⁻ is more stable than OH⁻ due to the larger size of sulfur, making H2S a stronger acid relative to water.
