Answer:
1 Å = 1.0 × 10⁻¹ nm
1 Å = 1.0 × 10² pm
Explanation:
Angstrom is the unit of the length which is equal to one ten-billionth of the metre or 10⁻¹⁰ m. It is represented by the symbol is Å .
Angstrom is not part of SI system of the units, but it is considered as a part of metric system.
Angstrom is used often in natural sciences as well as technology in order to express the sizes of atoms / molecules, and the lengths of the chemical bonds, etc.
1 Å = 10⁻¹⁰ m
1 nm = 10⁻⁹ m
1 pm = 10⁻¹² m
So,
1 Å = 1.0 × 10⁻¹ nm
1 Å = 1.0 × 10² pm
The best diagram to represent N2O is the second diagram.
The Lewis diagram is used to represent the way two or more atoms bond. This is possible by using lines to represent bonds and dots to represent electrons.
In the case of the molecule N2O bonding occurs in the following way:
- A triple bond is formed between the nitrogen atoms, which means, in the Lewis diagram the nitrogen atoms are connected with three lines.
- The oxygen atom connects to one of the nitrogen atoms.
- The nitrogen atom that is not connected to the oxygen will have 2 electrons represented by dots because the number of valence electrons is 5, but three were used in the triple bond.
- The oxygen atom will have 6 electrons represented by dots, which are equal to the number of valence electrons.

The structure of this oligopeptide is attached:
It consists of arginine - alanine - phenylalanine and leucine
From the picture we can see that N terminus charge is +1
Also Arginine is considered as basic amino acid with charge +1
C terminus charge is -1
At pH = 8, the whose pKa are less than pH will be deprotonated and the net charge will be +1
So the net charge of this oligopeptide is +1 at pH = 8
Answer:
C
