six different aqueous solutions are represented in the beakers below, and there total volumes are noted. (a) which solution has
the highest molarity? (b) which solutions have the same molarity? (c) if you mix solutions A and C, does the resulting solution have a higher molarity then, a lower then, or the same molarity as solution B? (d) after 50.mL of water is added to solution D, is its molarity high than, lower than or the same as the molarity of solution F after 75mL is added to it? (e) how much solvent must be evaporated from the solution of E for it to have the same molarity as solution A?

Answer:
Option (c) is correct.
Explanation:
According to 2nd law of thermodynamics, every spontaneous process is associated with increase in entropy ().
As sodium acetate crystallizes out spontaneously therefore it is associated with .
During crystallization, bond formation takes place which results evolution of heat. In other words, crystallization phenomenon is exothermic ().
So, the given crystallization process renders the following thermodynamic quantities- J/K and
J
Option (c) is correct.
Answer:
The diagram is attached.
Explanation:
Peptide just refers to two or more amino acids liking together. A dipeptide consists of two amino acids linking together. A polypeptide is more that two amino acids linking together.
