Answer:
Ionosphere.
Explanation:
The atmospheric layer that is represented by F is known as IONOSPHERE.
The characteristics of Ionosphere
1. It is considered to be located in the upper layer of the earth's atmosphere due to the location of region F.
2. It is ionized by solar radiation that contains an electrical charge.
3. It functions as a reflector. This can be observed in radio waves broadcasting.
Answer:
V = 25.7 L
Explanation:
To find the volume of Argon (Ar), you need to use the Ideal Gas Law equation. This looks like:
PV = nRT
In this formula,
> P = pressure (atm)
> V = volume (L)
> n = number of moles
> R = constant (0.0821 L*atm/K*mol)
> T = temperature (K)
While there is a different constant that can be used if you want to keep the pressure in mmHg, there is a more common constant used when the pressure is in atm. So, to find the volume, you need to (1) convert mmHg to atm (by dividing by 760) and then (2) calculate the volume (using Ideal Gas Law).
<u>(Step 1)</u>
600 mm Hg 1 atm
------------------- x --------------------- = 0.789 atm
760 mm Hg
<u>(Step 2)</u>
PV = nRT
(0.789 atm) x V = (0.825 mole)(0.0821 L*atm/K*mol)(300 K)
(0.789 atm) x V = 20.32
V = 25.7 L
