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.

To write a thesis for an exhibit prospectus, you should consider doing these:
- Your abstract should be on one page.
- A review of relevant literature containing 4-6 pages.
- The project proposal is 3-5 pages.
- A chapter outline in 1-2 pages and
- An annotated bibliography.
<h3>What is an exhibit prospectus?</h3>
An event exhibitor prospectus or proposal contains a summary of the event, an outline of the exhibition opportunities that are available at the event, and an explanation for why these opportunities are beneficial.
These 5 steps will guide you in creating an exhibitor prospectus:
- Create an eye-catching cover.
- Include information about the organization and event.
- Give the exhibitor an idea of who they are selling to.
- Detail opportunities and price of exhibiting.
- Conclude with contact information, rules and regulations and a potential booking form.

The excerpt that is from an opera aria by Mozart is; Excerpt A
What is the given Excerpt?
Mozart was an Austrian composer, widely recognized as one of the greatest composers in the history of Western music. Unlike any other composer in musical history, he wrote in all the musical genres of his day and excelled in every one. His taste, his command of form, and his range of expression have made him seem the most universal of all composers; yet, it may also be said that his music was written to accommodate the specific tastes of particular audiences.
Mozart wrote several successful operas, such as The Marriage of Figaro (1786), Don Giovanni (1787), and The Magic Flute (1791). Mozart also composed a number of symphonies and sonatas. His last symphony—the Jupiter Symphony—is perhaps his most famous.
The given excerpt which is seen from an audio listened to online is seen to be Excerpt A.

The options to fill in the gaps for the Long-run macroeconomic equilibrium are:
- equals
- intersects as a point on
<h3>What is macroeconomic equilibrium?</h3>
Macroeconomic equilibrium is an equilibrium situation that occurs when the quantities of the real GDP demanded equals the real GDP supplied at the point of intersection of the AD curve and the AS curve.
Long-run macroeconomic equilibrium occurs when aggregate demand equals short-run aggregate supply and they intersects as a point on the long-run supply curve.
In conclusion, Long-run macroeconomic equilibrium results in equilibrium of demand and supply of GDP.
