Answer:
No, as this promotes resistance of certain microorganisms and opportunistic infections with frequent use.
Explanation:
When being washed with antiseptic soaps, this generates the sweep of microorganisms from the commensal flora, giving rise to the reproduction and invasion of opportunistic microorganisms and, as a consequence, infections such as dermatitis.
On the other hand, these potentially pathogenic microorganisms, by proliferating and infecting and generating diseases, can acquire resistance methods against the repetitive contact of the antiseptics that these soaps present.
Answer:
B
Explanation:
Elements in a group are determined by the number of valence electrons
Elements in a period are determined by the number of electrons shell
The electronic configuration of the element is
2,8,8
the number of valence electron is 8 that means it is in Group 8/O
the number of electron shell is 3 that means it is in period (row) 3
Group 8/O elements are called Noble gases
Answer:
Depth Preception
Explanation:
Each eye sees a diffrent angle of a object. This is because the horizontal separation parallax of the eyes. If the object is close or near by the disparity will be huge.
Hope this helped you!
Water has greatest boiling and melting points because strong hydrogen bonds between water molecules (intermolecular force). That is because oxygen has largest electronegativity and smallest atomic radius of all elements in group. Other elements in this group do not form hydrogen bonds and they are gasses in room temperature, water is liquid and their boiling and melting points are lower. Boiling and melting point of hydrides gradually increases from H₂S to H₂Te because of increase of the radius and molecular mass of atoms from sulfur to tellurium, that is why intermolecular force of attraction of molecules increases. <span>
