The statement that correctly describes the nucleus of the atom is that most of the mass of an atom is located in the nucleus. The nucleus contains neutrons and protons. Rutherford reasoned that all of the atom's positively charged particles were contained in the nucleus and the negatively charged particles were scattered outside the nucleus. Both neutrons and protons are given a mass of one atomic mass unit or amu. Electrons have a mass many times smaller than 1 amu.

The p K a of lysine's carboxyl group, amino group, and side chain are 2.2, 9.0, and 10.5, respectively. If lysine is in a pH 13
Inessa [10]

Answer:

The net charge on each lysine molecule would be -1.

Explanation:

  • <u>When the pH is above 2.2</u> the deprotonated form of the carboxylic acid is more present, while the amino group and side chain (which is also amino) remain protonated (with a positive charge):

R-COOH ↔ R-COO⁻

R-NH₃⁺

R'-NH₃⁺

Net charge = +1

  • <u>When pH is above 9.0</u>, the carboxyl group remains deprotonated, while the amino group is deprotonated and the side chain is protonated:

R-COOH ↔ R-COO⁻

R-NH₂

R'-NH₃⁺

Net charge = 0

  • <u>When pH is above 10.5</u>, the carboxyl group remains deprotonated, while both the amino group and the side chain are deprotonated:

R-COOH ↔ R-COO⁻

R-NH₂

R'-NH₂

Net charge = -1

So at pH=13 (which is above 10.5) the net charge is -1.

Calculate the volume of 1.00 x 10^-2M KOH solution containing 3.00 x 10^-1 mol of solute?
ioda
Volume = ?

Molarity (M) = 1.00 x 10⁻² M

moles (n) = 3.00 x 10⁻¹ mol

V = n / M

V = 3.00 x 10⁻¹  / 1.00 x 10⁻²

V = 30 L
