Answer: a low 
and low pH.
Explanation:
pH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)
![pOH=-log[OH^-]](https://tex.z-dn.net/?f=pOH%3D-log%5BOH%5E-%5D)
Thus as pOH and are inversely related, a solution having higher pOH will have less amount of concentration. And a solution having more pOH will have less pH.
Thus a substance with a high pOH would likely have low concentration and low pH.
Answer:
B) Florine
Explanation:
Thus, fluorine is the most electronegative element.

V = ( 2.44 x 10⁻² ) x ( 1.4 x 10⁻³ ) x ( 8.4 x 10⁻³ )
V = 2.9 x 10⁻⁷ m³
