Whichever one has a negative enthalpy value.
Answer:
Gly-Ala
(Dipeptide).
Explanation:
A condensation reaction is a reaction in which two molecules combine to form a single molecule with the loss of a small molecule e.g water.
When two amino acids, such as alanine and glycine react, they yield a mixture of dipeptides (via dipeptide bond) and water. That is, The −OH from the carboxyl group (-COOH) of one amino acid combines with a hydrogen atom from the amine group (-NH2) of the other amino acid to produce water.

Answer:
1.23 M
Explanation:
Molarity of a substance , is the number of moles present in a liter of solution .
M = n / V
M = molarity
V = volume of solution in liter ,
n = moles of solute ,
Moles is denoted by given mass divided by the molecular mass ,
Hence ,
n = w / m
n = moles ,
w = given mass ,
m = molecular mass .
From the question ,
w = given mass of NaCl = 7.2 g
As we know , the molecular mass of NaCl = 58.5 g/mol
Moles is calculated as -
n = w / m = 7.2 g / 58.5 g/mol = 0.123 mol
Molarity is calculated as -
V = 100ml = 0.1 L (since , 1 ml = 1/1000L )
M = n / V = 0.123 mol / 0.1 L = 1.23 M
