Salicylic acid has a benzenic ring, one carboxylic functional group and one phenolic hydroxilic functional group.
Explanation:
Salicylic acid has the molecular formula C₇H₆O₃ and the chemical diagram is found in the attached picture.
On the benzenic ring it have two functional groups namely the carboxylic group (-COOH) and the phenolic hydroxilic group (-OH).
Salicylic acid is a precursor in synthesis of the aspirin (acetylsalicylic acid).

Answer:
[H₃O⁺] = 2.5 × 10⁻¹⁰ M
pH = 9.6
Explanation:
Step 1: Given data
Concentration of OH⁻ in the solution ([OH⁻]): 4.0 × 10⁻⁵ M
Step 2: Calculate the concentration of H₃O⁺ in the solution
Let's consider the self-ionization of water.
2 H₂O(l) ⇄ H₃O⁺(aq) + OH⁻(aq)
The <em>ion-product of water (Kw)</em> is:
<em>Kw = 1.0 × 10⁻¹⁴ = [H₃O⁺] × [OH⁻]</em>
[H₃O⁺] = 1.0 × 10⁻¹⁴/[OH⁻]
[H₃O⁺] = 1.0 × 10⁻¹⁴/4.0 × 10⁻⁵
[H₃O⁺] = 2.5 × 10⁻¹⁰ M
Step 3: Calculate the pH of the solution
We will use the following expression.
<em>pH = -log [H₃O⁺]</em>
pH = -log 2.5 × 10⁻¹⁰
pH = 9.6
Solute and solvent form a solution, which means two different kinds of molecules/atoms/compounds are mixed together, therefore, it is a mixture.
There is actually no membrane bounded or enclosed organelle that contain the genetic content and or information within a prokaryote. In bacteria, for instance the bacterial genome, which is that of a enclosed single double stranded circular DNA molecule is associated with histone like proteins and found within the cytoplasmic region of a cell in an irregular manner. It is termed the nucleoid.
