The answer would be: <span>D. Kb for HS–
</span>
Kb is the dissociation constant of an acid/base molecule. The word b in Kb is base, which means the formula should have an OH- ion inside it. Ka would be the opposite of Kb where the formula has H+ ion.
In this question, the formula is: [H2S][OH-]/ [HS-]
Since there are OH- ion. Since H2S is acid and HS- is base, I think it should be <span>Kb for HS–

The structure of proteins is ultimately determined by the sequence of nucleic acids.
A ecosystem is SUSTAINABLE if it can continue to function over long periods of time.
