As one moves up in altitude, the atmospheric pressure decreases. in vail, colorado (altitude 8022 ft or 2445 m), the atmospheric pressure is approximately 570 mmhg. what would the partial pressure of oxygen be in vail?

120 mm Hg

Explanation:

Given that,  

Height = 8022 ft/2445 m

Atmospheric pressure = 570 mm Hg

In order to calculate the partial pressure of oxygen, at first, it is required to calculate the mole fraction of Oxygen.

Mole fraction of Oxygen = % of Oxygen in the air

                                         = 20.95 % = 0.2095

Now, we know that,

⇒ Partial pressure of oxygen = Total pressure × mole fraction of Oxygen

                                                = 570 × 0.2095

                                                = 119.415 mm Hg

Therefore, the partial pressure of oxygen in Vail is approximately 120 mm Hg.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
