Peptide bonds are amide connections between two amino acids' -carboxyl and -amino groups.
The covalent link created by the dehydration reaction (loss of a water molecule) between the carboxyl group of one amino acid and the amino group on the next is known as a peptide bond. Peptide bonds are created in polypeptides through a condensation reaction between the carboxyl groups of one amino acid and the amino groups of the following amino acid, all while removing water. When the carboxyl group of one molecule combines with the amino group of the other molecule, releasing a molecule of H2O as a result, a peptide bond is created between the two molecules.

Answer:
0.893mol
Explanation:
n = m ÷ M
= 275 ÷ (23 + 80)
= 2.67 mol
* now use the Mol ratio *
NaBr : FeBr3
6 : 2
2.67 : x
5.67 = 6x
n( FeBr3 ) = 0.893 mol
Answer:
Minimizing repulsion by maximizing the bond angles
Explanation:
VSEPR is defined as 'valence shell electron pair repulsion' theory. The key principle is that repulsion of adjacent lone pairs of electrons or the electrons that are shared within a bond creates bond angles.
The bond angles are maximized in order to minimize the repulsion in the most stable geometrical shape of the molecule.
That said, in VSEPR theory we tend to achieve the greatest possible angles between the bonds and lone pair electrons in order to obtain the lowest repulsion between them.
In very basic terms alchemy is magic and chemistry is scientific.
