Answer:

an Additional shell

Explanation:

Potassium has an additional energy level when compared to sodium. This is due to an extra shell added. In the periodic table when you go down the group, the atomic radius increases due to increasing energy levels.

The atomic radius mean the distance from the center of the nucleus to the valance shell. it actually describes the size of the atom

Answer:

The answer is Dissemination of components controlled by electron design.  

Explanation:

the Aufbau rule, the Pauli rejection guideline, and Hund's rule,tell you how to discover the electron designs of particles. As indicated by the aufbau standard, electrons possess the orbitals of most reduced vitality first, Pauli-prohibition rule, and Hund's Rule. The electronic setup of cations is doled out by evacuating electrons first in the peripheral p orbital, trailed by the s orbital lastly the d orbitals.

An over-the-counter medicated foot powder contains camphor, eucalyptus oil, lemonoil, and zinc oxide. Only one of the ingredient
attashe74 [19]

Answer:

Zinc oxide is the antimicrobial in the medicated foot powder.

Explanation:

Zinc oxide (ZnO) is used to treat several skin conditions such as acne, dermatitis, eczema, etc because it has antibacterial and antifungal properties. This property of the ZnO depends on its size i.e., the smaller the size of ZnO, the stronger antimicrobial activity it has. So, the ZnO nanoparticles are more efficient.

The zinc oxide interacts with the sulfur atoms in microbial proteins and denatures them and destroys their function. This action completely inhibits microbial growth. The treatment with zinc oxide causes the reduced production of conidia in fungi, damages their hyphae and inhibits their ability to produce mycotoxins.

The compounds containing zinc such as ZnSO4, Zn(ClO4)2, etc also have antifungal and antimycotoxin properties that can cause changes in the fungi cell structure. Also, the free radicals formed on the surface of the ZnO nanoparticles can cause damage to the lipids in the bacterial cell membranes that can lead to the leakage and breakdown of the bacterial cell membranes.

How many phase rule variables must be specified to fix the thermodynamic state of each of the following systems? Show how you de
Murrr4er [49]

Answer: (i) F = 2

(ii) F = 3

(iii) F = 2

Explanation:

We would be applying the famous Gibbs Phase Rule to explaining this problem;

By applying the formula;

F+P = C +2

Where P = this represent the phase

F = this is called the degree of freedom

C = this represent the component in the system

Ok let us begin;

(i). from this we can see that there are 2 components i.e. (water + ethanol) and the phase in question is a vapor phase + liquid phase.

So from the formula;

F = C-P+2

F = 2 – 2 + 2 = 2

Therefore, F = 2.

(ii). Also, from the statement, we can figure there are 3 components, while the phases are two like the previous one above, i.e. liquid + vapor

F = 3 – 2 + 2 = 5 – 2 = 3

F = 3

(iii). From this statement, we can figure there are 3 components, and the phases are 3 i.e. (2 liquid phases + 1 vapor phase)

From the formula;

F = 3 – 3 + 2 = 0 + 2

F = 2
