Death valley in california is 86 m below sea level. will the partial pressure of oxygen in death valley be the same, lower or higher than the partial pressure of oxygen at sea level?

Air pressure generally decreases (gets "thinner") with increasing altitude. Therefore, it generally increases with decreasing altitude. Since Death Valley is below sea level, its altitude is lower than sea level and the partial pressure of oxygen in Death Valley is therefore higher.

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.
