So the question ask to calculate the Ks of the monoprotic acid where as it is dissolved in water to produce 0.0136 M solutions and the PH result of the solutions is 2.45. So the Ka of the problem is 1.25 x 10^-3. I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarifications about the problem
Answer:
At about 51 °C
Explanation:
Hello there!
In this case, according to the attached solubility chart of potassium nitrate, our first step for this problem is to calculate the grams of this solute in 100 g given that 23 g are soluble in 25 g of water:
Thus, such solubility of 92 g in 100 g of water is exhibited at about 51 °C.
Regards!
Given what we know, we can confirm that when an excited electron spontaneously emits a photon, the energy released is electromagnetic energy.
<h3>What is a Photon and what energy does it release when being emitted?</h3>
- A photon is a particle.
- This means that it is one of the smallest forms of matter that we can study.
- Photons form electromagnetic fields.
- Therefore, when being emitted by an electron, photons release electromagnetic energy.
Therefore, we can confirm that when an excited electron spontaneously emits a photon, the energy released is electromagnetic energy due to the properties of the photon being emitted.

The bond angle obtained based on the geometry of the molecule alone is known as the predicted bond angle.
When a compound is formed, the less electronegative atom in the compound is called the central atom in the molecule. The angle formed by the nuclei of two surrounding atoms with the nucleus of the central atom in a structure is called a bond angle.
The bond angle is usually based on the geometry of the molecule. The expected geometry can be deviated for certain reasons such as the presence of lone pairs on the central atom in the molecule. The bond angle obtained based on the geometry of the molecule alone is known as the predicted bond angle.

Answer:
Final concentration of the dilute solution is 1.2M
Explanation:
Dilution formula must be applied in this case to determine the molar concentration of the dilute solution:
M concentrated . Volume concentrated = Volume diluted . M diluted
75 mL . 8 M = 500 mL . M diluted
(75 mL . 8 M) / 500 mL = M diluted
M diluted = 1.2 M
