Answer:

Shifts to the left.

Shifts to the right.

Explanation:

Based on Le Châtelier's principle, when a change occurs in a system in equilibrium, the system will try to counteract the change that was made.

In the equilibrium:

2NO (g) + H₂ (g) ⇌ N₂O (g) + H₂O (g) + 36 kJ (heat)

If N₂O is added, the equilibrium shifts to the left trying to decrease the concentration of N₂O added.

If H₂ is added, the equilibrium shifts to the right trying to decrease the concentration of H₂ added

AlekseyPX

Answer:

There will be 3 peaks.

Relative height of the atomic peaks would be; 158, 160 and 162

Explanation:

We are told that Bromine has two isotopes namely 79Br and 81Br in a 1 : 1 ratio (50 : 50).

This means that a compound which contains 1 bromine atom will have two peaks in the molecular ion region but it depends on which bromine isotope is contained in the molecular ion.

Thus;

Relative height of atomic peaks is given by;

m/z = 79Br¯ 79Br+ = 158

79Br¯ 81Br+ = 160

81Br¯ 81Br+ = 162

miv72 [106K]

Answer:

- The formation of a peptide bond involves a dehydration reaction.

- A tripeptide contains three amino acid residues.

Explanation:

Peptide bonds are a type of covalent bonds that form between amino acid molecules. A peptide bond links two amino acids together by removing an hydrogen atom from the amine functional group (-NH2) and an hydroxyl (OH) from carboxylic functional group (-COOH) to release a water molecule. Hence, the formation of a peptide bond involves a dehydration reaction i.e loss of water.

This linking of one amino acid to another via a peptide bond forms a polypeptide and consequently a protein molecule. In other words, proteins are polymers of peptides. However, the linkage of three amino acids is called TRIPEPTIDE
