Answer:
a. Gly-Lys + Leu-Ala-Cys-Arg + Ala-Phe
b. Glu-Ala-Phe + Gly-Ala-Tyr
Explanation:
In this case, we have to remember which peptidic bonds can break each protease:
-) <u>Trypsin</u>
It breaks selectively the peptidic bond in the carbonyl group of lysine or arginine.
-) <u>Chymotrypsin</u>
It breaks selectively the peptidic bond in the carbonyl group of phenylalanine, tryptophan, or tyrosine.
With this in mind in "peptide a", the peptidic bonds that would be broken are the ones in the <u>"Lis"</u> and <u>"Arg"</u> (See figure 1).
In "peptide b", the peptidic bond that would be broken is the one in the <u>"Phe"</u> (See figure 2). The second amino acid that can be broken is <u>tyrosine</u>, but this amino acid is placed in the <u>C terminal spot</u>, therefore will not be involved in the <u>hydrolysis</u>.
Answer:
120, 180,90
Explanation:
According to VSEPR theory with a central atom with 5 gropus, we will expect a trigonal bipyramidal structure. This structure look like a trgonal plane containing the three iodine atoms, and above and below this plane we have the two bromine atoms 180º apart. Why can we say this? The key is that the problem is telling us the PIₐCl₂ is a nonpolar molecule and this shape is the only one that will result in a nonpolar structure. The Chlorine atoms will be in the axial positions 180 degrees apart and the bond angles will be :
I-P- I 120º
Cl-P-Cl 180º
I-P-Cl 90 º
See attachment.
The two Cl atoms are in the axial positions, and the three I atoms are in what we call equatorial position in the trigonal plane.
Any other arrangement will result in a polar molecule. Place a Cl atom in the trigonal plane and I in the axial position, and you can see that the molecule will be polar because the positions will no longer be equivalent and the dipoles will not cancel each other.
Halides is the term given to the ions of halogens. Halogens are the second-to-the-last column or period in the periodic table. Examples are chlorine, fluorine, bromine and iodine. Halides are all soluble in water except when combine with silver, lead and mercury. <em>Therefore, the generalization we can make is that silver halides are insoluble in water,</em>

Answer:
The pressure is 4.939 atm
Explanation:
As we know
PV = nRT
where P is the pressure
V is the volume
n is the total number of moles
R is the gas constant
and T is the temperature
Substituting the given values we get -
The pressure is 4.939 atm
