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.
<h3>What is a protein?</h3>
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:
All of the above processes have a ΔS < 0.
Explanation:
ΔS represents change in entropy of a system. Entropy refers to the degree of disorderliness of a system.
The question requests us to identify the process that has a negative change of entropy.
carbon dioxide(g) → carbon dioxide(s)
There is a change in state from gas to solid. Solid particles are more ordered than gas particles so this is a negative change in entropy.
water freezes
There is a change in state from liquid to solid. Solid particles are more ordered than liquid particles so this is a negative change in entropy.
propanol (g, at 555 K) → propanol (g, at 400 K)
Temperature is directly proportional to entropy, this means higher temperature leads t higher entropy.
This reaction highlights a drop in temperature which means a negative change in entropy.
methyl alcohol condenses
Condensation is the change in state from gas to liquid. Liquid particles are more ordered than gas particles so this is a negative change in entropy.
