Maturation replaces breath under this states of stress where the o2 allow by muscle cells is more prominent than oxygen is accessible.
They contain the same number of molecules; however, the masses can differ depending on the molar masses of the substances.
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.
Answer:
1.7x10²³ Fluorine atoms are present
Explanation:
To solve this question we must know that, to find the amount of atoms of a substance from its mass, we have, as first, to convert this mass to moles using molar mass of the substance. With the moles we can find the amount of molecules using Avogadro's number. And with the formula we can know the atoms presents:
<em>Moles Fluorine (F₂, Molar mass: 37.997g/mol)</em>
5.3g * (1mol / 37.997g) = 0.139 moles F₂
<em>Molecules F₂:</em>
0.139 moles F₂ * (6.022x10²³molecules / mol) = 8.4x10²² molecules F₂
As 1 molecule of F₂ contains 2 atoms of Fluorine:
8.4x10²² molecules F₂ * 2 =
<h3>1.7x10²³ Fluorine atoms are present</h3>
