Answer:
The concentration of hydroxide ions is 3.02*10⁻³ M
Explanation:
The pOH (or OH potential) is a measure of the basicity or alkalinity of a contamination and is defined as the negative logarithm of the activity of the hydroxide ions. That is, the concentration of OH- ions:
pOH= -log [OH-]
The pOH has a value between 0 and 14 in aqueous solution, the solutions with pOH being greater than 7 being acidic, and those with pOH less than 7 being basic.
If pOH= 2.52 then
2.52= -log [OH-]
[OH-]= 3.02*10⁻³ M
<u><em>The concentration of hydroxide ions is 3.02*10⁻³ M</em></u>

Answer:
electron moving from a lower energy to a higher level of energy
<span>To prove the Pythagorean Theorem based on similarity of triangles, you can always use the 2nd construction.
The 2nd construction is achieved by drawing a perpendicular line joining between the right angle of the triangle and the hypothesis (as shown in the attachment).
Note: The Pythagorean Theorm is stated as follows:
(length of hypotenuse)^2 = (length of side1)^2 + (length of side2)^2</span>
