Answer:
A. glycine (NH 2 CH 2 COOH).
Explanation:
Hello,
In this case, we understand amino acids as organic compounds that assemble to form high order molecules called proteins, therefore, they are the building blocks of life. Structurally, as shown on the first attached picture, they make up of both an amino group and a carboxily group having the organic chain below. In such a way, the only listed compound that matches with such the aforesaid definitions is glycine whose structure is shown on the other attached document.
Best regards.

Answer:
1.33 Å
Explanation:
Given that the edge length , a of the KCl which forms the FCC lattice = 6.28 Å
Also,
For the FCC lattice in which the anion-cation contact along the cell edge , the ratio of the radius of the cation to that of anion is 0.731.
Thus,
.................1
Also, the sum of the radius of the cation and the anion in FCC is equal to half of the edge length.
Thus,
...................2
Given that:
To find,
Using 1 and 2 , we get:
<u>Size of the potassium ion = 1.33 Å</u>
