The question is incomplete. Complete question is:
<span>Consider the given acid ionization constants. identify the strongest conjugate base.
</span>HNO2(aq) 4.6×10−4
HCHO2(aq) 1.8×10−4
HClO(aq) 2.9×10−8
HCN(aq) 4.9×10−10
.........................................................................................................................
Correct Answer: option
4: HCN(aq) 4.9×10−10
Reason:
According to Lowry and Bronsted theory of acid and base. Stronger the acid, weaker will be the conjugate base.
In present case, ionization constant is highest of HCN i.e. 4.9×

. This signifies that, it is the strongest acid. Hence, conjugate base associated with this acid (i.e.

) is the weakest.
Answer : The mass of
is, 295.323 grams
Solution :
First we have to calculate the moles of
.

Now we have to calculate the moles of NaBr.
The balanced chemical reaction is,

From the balanced reaction we conclude that
As, 2 moles of
react with 2 moles of 
So, 2.87 moles of
react with 2.87 moles of 
Now we have to calculate the mass of NaBr.


Therefore, the mass mass of
is, 295.323 grams
Answer:
Well, it could be B or D but I would say B.
Explanation:
The structure of an organelle is usually fit to its function so it is most likely B.
