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–

Answer:
a. NaNO3 and CuCl2
Explanation:
The other 3 react as follows:
Ba(OH)2 and HNO3 ---> BaNO3 + H2O
CaCl2 + Na3PO4 ---> CaPO4 + NaCl
AgNO3 + HCl ---> AgCl + HNO3
In reaction 2 moles of SO2 reacts with 5 moles of C...
So for 0.5 mole of SO2 we should have the same ratio ...
C/SO2 = 5/2
Is that clear?
Answer:
NH3
Explanation:
The "tri" attached to the trihydride means 3. So your hydrogen is going to have 3 atoms.
