Answer:
Whats the question?? if its ratios then 4:4 and if its fractions red: 4/8 and green:4/8
Explanation:
The hydronium ion concentration of the solution with given value of pOH is 7.94 × 10⁻⁸M.
Option D) is the correct answer.
<h3>What is pH of solution?</h3>
The pH of a solution is defined as the logarithm of the reciprocal of the hydrogen ion concentration [H+] of the given solution.
From the formular;
pH = -log[ H⁺ ]
pH + pOH = 14
Given that;
- Hydronium ion concentration OH⁻ = ?
First we find the pH
pH + pOH = 14
pH + 6.90 = 14
pH = 14 - 6.90
pH = 7.1
Now, from the above expression;
pH = -log[ H⁺ ]
Hence;
[ H⁺] = 10^(-pH)
[ H⁺] = 10^(-7.1)
[ H⁺] = 7.94 × 10⁻⁸M
Therefore, the hydronium ion concentration of the solution with given value of pOH is 7.94 × 10⁻⁸M.
Option D) is the correct answer.

An example of Lesson 11.1 practice a geometry question is to find the length of ∧ AB in the image attached..
<h3>What is the length of the angle about?</h3>
To be able to find the length of (angle) ∧AB, one must:
When the Arc length of AB 
2π(5) = 13.09 meters
Therefore, the length of the angle is 13.09 meters.
