Answer:
Si.
Explicación:
Sí, el método de cristalización se utiliza para separar la sal del agua y obtener los componentes de la sal y del agua por separado. La cristalización es un método o técnica que se utiliza para purificar compuestos sólidos. Este proceso funciona mejor debido a las diferentes solubilidades del compuesto deseado y las impurezas que están presentes en un solvente dado. El proceso de cristalización implica enfriar agua salada para formar cristales de hielo puro. Luego, los cristales de hielo se separan de la salmuera no congelada, se lavan para eliminar la sal residual y luego se derrite la solución para producir agua dulce.
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

Answer : The molecular shape of 
is trigonal pyramidal and bond angle between O-S-O is 
Explanation :
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
In the Lewis-dot structure the valance electrons are shown by 'dot'.
The given molecule is,
As we know that sulfur has '6' valence electrons and oxygen also has '6' valence electron.
Therefore, the total number of valence electrons in = 6 + 3(6) + 2 = 26
According to Lewis-dot structure, there are 8 number of bonding electrons and 18 number of non-bonding electrons or lone pair electrons.
The Lewis-dot structure of is shown below.
Formula used :
![\text{Number of electron pair}=\frac{1}{2}[V+N-C+A]](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20electron%20pair%7D%3D%5Cfrac%7B1%7D%7B2%7D%5BV%2BN-C%2BA%5D)
where,
V = number of valence electrons present in central atom
N = number of monovalent atoms bonded to central atom
C = charge of cation
A = charge of anion
Now we have to determine the hybridization of the given molecule,
![\text{Number of electrons}=\frac{1}{2}\times [6+2]=4](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20electrons%7D%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%5B6%2B2%5D%3D4)
The number of electron pair are 4 that means the hybridization will be 
and the electronic geometry of the molecule will be tetrahedral.
But as there are 3 atoms around the central sulfur atom, the fourth position will be occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be trigonal pyramidal and the bond angle between O-S-O is less than 
due to repulsion between lone and bond pair of electrons.
