Answer:Biopolymer: the monomeric amino acids are linked through an
amide bond (the carboxylic acids of one AA with the α-amino
group of a second)
Explanation:
The chlorine usually forms a Chloride ion.
The Chlorine gains an electron leaving it 17 protons and 18 electrons. Since it has 1 more electron than protons, chlorine has a charge of −1, making it a negative ion. When ions form, atoms gain or lose electrons until their outer energy level is full.
What do you mean by Chlorine forming an ion?
Chlorine has one electron when it forms an ion to be an anion with a charge of -1. The charge of an ion, and thus the number of electrons the atom will gain or lose. If an atom has less than four valence electrons, it will lose them to become a cation.
The chloride ion is the anion Cl− which is formed facilitating important chemical reactions coupled with its usage in the everyday world.

Answer:
Mass is 725.46g/cm
Explanation:
Mass = density × volume = 22.6g/cm^3 × 32.1cm^2 = 725.46g/cm
