The pH of the monoprotic weak acid is 2.79.
<h3>What are weak acids?</h3>
The weak acids are the acids that do not fully dissociate into ions in the solution. Strong acids fully dissociate into ions.
The chemical reaction is HA(aq) ⇄ A⁻(aq) + H⁺(aq).
c (monoprotic acid) = 0.33 M.
Ka = 1.2·10⁻⁶
[A⁻] = [H⁺] = x
[HA] = 0.33 M - x
Ka = [A⁻]·[H⁺] / [HA]
2. 6 × 10⁻⁶ = x² / (0.33 M - x)
Solve quadratic equation: [H⁺] = 0.000524 M.
pH = -log[H⁺]
pH = -log(0.000524 M)
pH = 2.79
Thus, the pH of the monoprotic weak acid is 2.79

Answer:
Explanation:
In a chemical equation, the reactants are written on the left, and the products are written on the right. Chemical equations should contain information about the state properties of products and reactants, whether aqueous (dissolved in water — aq), solid (s), liquid (l), or gas (g). hope that helped
The Correct Answer is Eletric Current I think
1. Mitosis is a process where a single cell divides into two identical daughter cells (cell division).
2. Mitosis is important because it plays an important part in the development of embryos, and it is important for the growth and developemet of our body as well.
3. The four phases of mitosis are: Prophase, metaphase, anaphase, and telophase.
4. Two gap phases (G1 and G2); an S (for synthesis) phase, in which the genetic material is duplicated.
5. During S phase all of the chromosomes are replicated.
