Sodium acetate spontaneously crystallizes out of a supersaturated solution upon standing or upon the addition of a seed crystal.
1 answer:
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.

Procaryotic structural components consist of macromolecules such as DNA, RNA, proteins, polysaccharides, phospholipids, or some combination thereof. The macromolecules are made up of primary subunits such as nucleotides, amino acids and sugars (Table 1). It is the sequence in which the subunits are put together in the macromolecule, called the primary structure, that determines many of the properties that the macromolecule will have. Thus, the genetic code is determined by specific nuleotide base sequences in chromosomal DNA; the amino acid sequence in a protein determines the properties and function of the protein; and sequence of sugars in bacterial lipopolysaccharides determines unique cell wall properties for pathogens. The primary structure of a macromolecule will drive its function, and differences within the primary structure of biological macromolecules accounts for the immense diversity of life.
