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.
A. CI, Br
Explanation:
Different kinds of atoms bind their valence electrons with various amounts of energy. In order to remove the valence electrons, enough energy must be available.
The amount of energy required for the removal of an electron is the ionization energy or ionization potential.
The ionization energy depends on:
- Nuclear charge
- Atomic radius
- Sublevel accomodating the electron to be removed.
- Special stability of half or fully filled sublevels.
Across a period, the ionization energy increases.
Down a group ionization energy decreases due to increasing atomic radii.
Cl and Br are in the same periodic group. Cl is element number 2 and Br is element 3 in the group of the halogens.
Therefore, Cl will have a higher ionization energy compared to Br.
