Answer:
The correct option is: Isoleucine
Explanation:
Peptides are the biological molecules containing amino acids which are linked together by peptide bonds. A polypeptide is a peptide chain in which more than 20 amino acids are linked together by peptide bond.
All polypeptide chains have a N-terminal and a C-terminal.
The N-terminal of a polypeptide is also known as the amino terminal. The N-terminal has a free amine group, which is generally on the left hand side of the polypeptide chain.
Therefore, the N-terminal or the amino terminal of the given polypeptide is Isoleucine (I).
The coefficient of any substance in a chemical equation indicates the number of moles of that substance which are present. We can see from its chemical formula that tetraiodine nonaoxide contains four iodine atoms and nine oxygen atoms. If the coefficient is two, then the total iodine atoms will be eight and the total oxygen atoms will be 18. Because the law of conservation of mass holds, an equal amount must be accounted for on the other side of the chemical equation. Therefore, the first option is correct.
Answer:
Scandium(III) fluoride, ScF3, is an ionic compound. It is slightly soluble in water but dissolves in the presence of excess fluoride to form the ScF63− anion.

Answer:
Mole fraction of methanol will be closest to 4.
Explanation:
Given, Mass of methanol = 128 g
Molar mass of methanol = 32.04 g/mol
The formula for the calculation of moles is shown below:
Thus,
Given, Mass of water = 108 g
Molar mass of water = 18.0153 g/mol
The formula for the calculation of moles is shown below:
Thus,
So, according to definition of mole fraction:
<u>Mole fraction of methanol will be closest to 4.</u>
Answer:
The cell reaction reaches equilibrium quickly and the cell emf becomes zero.
Explanation:
The purpose of a salt bridge is not to move electrons from the electrolyte, its main function is to maintain charge balance because the electrons are moving from one-half cell to the other.
A solution of a salt that dissociates easily is normally used. Water is ineffective at functioning as a salt bridge. Hence the effect stated in the answer.
