Predict the dominant type of bonding by considering electronegativity.

If the atoms that are bonding have identical electronegativities, then it's a completely nonpolar covalent bond. This doesn't happen in the real world unless the two atoms are of the same element. In a practical sense, any two elements with an electronegativity difference less than 0.3 is considered to be nonpolar covalent.
As the difference between the atoms increases, the covalent bond becomes increasingly polar. At a polarity difference of 1.7 (this changes depending on who you ask) we consider it no longer to be a covalent bond and to be the electrostatic interactions characteristic in an ionic compound.
Just so you know, you shouldn't take these values as exact. ALL interactions between adjacent atoms involve some sharing of electrons, no matter how big the difference in electronegativity. Sure, you wouldn't expect much sharing in KF, but there's a little sharing of electrons anyway. There's certainly no big cutoff that happens at a difference of 1.7 Pauling Electronegativity units.

How does elevation affect climate?
Kisachek [45]

As elevation increases, air density decreases resulting in a decreased ability to hold heat.

<h3>Effect of elevation on climate</h3>

As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further and the temperature decreases.

P = ρgh

where;

  • P is the air pressure
  • ρ is air density
  • h is elevation
  • g is acceleration due to gravity

As the pressure decreases, air molecules spread out further and the temperature decreases. The decrease in temperature affects the amount of heat that air can hold.

Thus, as elevation increases, air density decreases resulting in a decreased ability to hold heat.

A client visits the primary healthcare provider with severe facial acne. the primary healthcare provider prescribes tretinoin. w
alukav5142 [94]
Tretinoin is a naturally occurring metabolite of retinol in the retinoid class, including natural and synthetic analogues. It is the acid form of vitamin AIt acts on cell growth and differentiation. Its main use is the treatment against acne thanks to its keratolytic and anti-inflammatory properties. Tretinoin is also used in the treatment of acute myeloid leukaemia type 3 (AML 3).

SIDE EFFECTS:
Among the expected effects, side effects may occur. Signs of an allergic reaction include: hives, difficulty breathing, swelling of the face, lips, tongue or throat;

It should be known that tretinoin can make you more sensitive to the sun, so use sunscreen every day, and wear protective clothing outdoors.
Cholesterol and triglycerides should be done before and during treatment because this drug could increase their values
Some patient with leukaemia treated by tretinoin has suffered from The syndrome of retinoic acid which is characterized by fever, dyspnea, acute respiratory distress...

In which type of reproduction can cells divide through the process of mitosis ?
Aleks04 [339]
<span>Mitosis is carried out for growth and development processes. The cell divide and multiply for growing and removing the worn out cells/damaged cells. Two identical daughter cells are formed in mitosis. Errors in the same may cause genetic disorders, Sex cells divide by the process of meiosis. </span>
