The kind of molecule in this pizza is a protein because it is a polymer, <u>hydrophilic</u>, and it's made up of oxygen, hydrogen, and sulfur atoms.
<h3>What is an amino acid?</h3>An amino acid refers to a simple and organic chemical compound that consist of an acidic carboxyl group (COOH), a basic amino group (), and a unique side chain group.
A protein can be defined as a <u>hydrophilic</u>, macromolecule (polymer) that is formed as a result of the union of many amino acids.
Generally, a protein contains the following chemical elements:
In conclusion, the kind of molecule in this pizza is a protein because it is a polymer, <u>hydrophilic</u>, and it's made up of oxygen, hydrogen, and sulfur atoms.

Answer:
15.33
Explanation:
Given parameters:
Mass of KOH = 121g
Volume of solution = 100mL = 0.1dm³
Molar mass of KOH = 56.11g/mol
Unknown:
pH of the solution = ?
Solution:
To find the pH, we must first know the concentration of the solution obtained by mixing KOH up to this volume.
This can be done by finding the molarity of the solution.
Molarity =
Number of moles of KOH = =
= 2.16mole
Input parameters;
Molarity of solution = = 21.6moldm⁻³
KOH → OH⁻ + K⁺
21.6 21.6 21.6
In the solution we have 21.6moldm⁻³ of OH⁻ which is need to find the pH;
pOH = -log₁₀(OH⁻)
pOH = -log₁₀21.6
pOH = -1.33
Since pH + pOH = 14
pH = 14 - (-1.33) = 15.33
