Which statement correctly explains why H2S is a stronger acid than H2O ?(1 point) Responses Sulfur (S) has a smaller atomic size than oxygen (O), so H2S completely dissociates while H2O does not dissociate. Sulfur ( S ) has a smaller atomic size than oxygen ( O ), so H sub 2 S completely dissociates while H sub 2 O does not dissociate. Sulfur (S) has a larger atomic size than oxygen (O), and the HS− conjugate base is weaker than the OH− conjugate base. Sulfur ( S ) has a larger atomic size than oxygen ( O ), and the H S raised to the negative power conjugate base is weaker than the O H raised to the negative power conjugate base. Sulfur (S) has a larger atomic size than oxygen (O), and the HS− conjugate base is stronger than the OH− conjugate base. Sulfur ( S ) has a larger atomic size than oxygen ( O ), and the H S raised to the negative power conjugate base is stronger than the O H raised to the negative power conjugate base. Sulfur (S) has a smaller atomic size than oxygen (O), so H2S partly dissociates while H2O does not dissociate.

GPT-4o mini · Answer

The correct explanation for why H2S is a stronger acid than H2O is:

Sulfur (S) has a larger atomic size than oxygen (O), and the HS− conjugate base is weaker than the OH− conjugate base.

This is because the larger atomic size of sulfur allows the H-S bond to be weaker than the H-O bond in water, making it easier for H2S to donate a proton (H+) and therefore behave as a stronger acid. Additionally, the conjugate base HS− is weaker compared to OH−, which is consistent with the trend that weaker conjugate bases correspond to stronger acids.
