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

s is antimicrobial. Which one? How does it act against fungi?
The zinc oxide is the antimicrobial in the foot powder. The zinc interacts with sulfur atoms in proteins, denaturing the proteins and destroying their function.

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.

Why do you think lone pairs of electrons create greater repulsion when located near other
Sedaia [141]

When there are lone pairs on the valence shell of the central atom in a molecule, the bond angle is decreased.

The shape of molecules depend on the number of electron pairs on the valence shell of the molecules. These electron pairs could be lone pairs or bond pairs. Lone pairs occupy more space around the central atom since it is attracted to only one nucleus compared to bond pairs which are attracted to two nuclei.

When lone pairs are present on the central atom in a molecule, they tend to "squeeze" the molecule thereby decreasing the bond angle in the molecule. Hence, presence of one or more lone pairs of electrons make the bond angles get smaller.

Describe how the mass spectrometry readout is consistent with the chemical structure of hydrochloric acid.
FromTheMoon [43]

The reading of mass so of hydrochloric acid involves sequence of analysis including:

  • Sample introduction
  • Analyte ionization
  • Mass analysis
  • Ion detection
  • Data processing

The chemical structure of hydrochloric acid is HCl

<h3>What is mass spectrometry?</h3>

Mass spectrometry is defined as a special analytical technique that is used to measure the mass ratio of ions.

It is used to determine the masses of atoms of chemical elements

So therefore, the reading of mass so of hydrochloric acid involves sequence of analysis including:

  • Sample introduction
  • Analyte ionization
  • Mass analysis
  • Ion detection
  • Data processing

Horned animals have different sizes of horns. The size of their horns can affect their ability to
Fofino [41]

Answer:

survival of fit individuals

Explanation:

I believe its survival of fit individuals because the animals with different horns are going to be able to find a mate or provide better depending on their horn and its kind of like natural selection in the sense those who have genetically better (??) horns are more likely to survive.  Hope it helps but it might be a little bit of a confusing explanation.
