A covalent bond is the bond between two nonmetals.
Hope this helped!

Answer:
It would be the last one because the way earth is tilted the sun rays would be pointing at the Northern Hemisphere more than the Southern Hemisphere
The total pressure is 6.7 atm. The mole fractions of O₂ and Ar are 0.42 and 0.037.
<em>p</em>(Tot) = <em>p</em>(N₂) + <em>p</em>(O₂) + <em>p</em>(Ar) + <em>p</em>(He) = 3.5 atm + 2.8 atm + 0.25 atm + 0.15 atm = 6.7 atm
χ(O₂) = p(O₂)/p(Tot) = 2.8 atm/6.7 atm = 0.42
χ(Ar) = p(Ar)/p(Tot) = 0.25 atm/6.7 atm = 0.037
