Quantitative measurements are numerical values, they involve amounts and units like measuring things. Qualitative observations appeal to the five senses, like what does the interaction look and sound like
Answer:
<h2>B</h2>
Explanation:
The proton motive force; is the free energy released during the oxidation of NADH or FADH2 and it is stored both as an electric potential and a proton concentration gradient across the inner membrane.
The purpose of proton motive force is that the movement of protons back across the inner membrane, driven by this force, is used to the synthesis of ATP from ADP and Pi by ATPase/ ATP synthase (F0F1 complex ).
The potassium chloride is KCl. The gram formula mass of KCl is 39+35.5=74.5 g/mol which means 74.5 g per mole of KCl. So the mass of KCl is 6.90*74.5=514 g.

Explanation:
A compound or molecule which will have least dissociation and that is not able to given hydrogen ion easily upon dissociation will also have a low value of 
.
Dissociation of the given compounds or species will be as follows.
As, chemical formula of bicarbonate is 
and due to the presence of a negative charge it is difficult to lose a positively charged hydrogen ion. This is because oppositely charged ions will be bonded by strong force of attraction.
Hence, it will not easily lose a hydrogen ion due to which bicarbonate has the lowest .
Thus, we can conclude that out of the given species bicarbonate has the lowest .
