sample containing a mixture of only these
gases at exactly one atmosphere pressure, the
partial pressures of carbon dioxide and ni-
trogen are given as Pco, = 0.285 torr and
PN = 634.034 torr. What is the partial pres-
sure of oxygen?
Answer in units of torr.
Answer:
125.681 torr
Explanation:
The formula to calculate the partial pressure of oxygen:
P(O2) = Pcommon - PCO2 - PN2
1 atm = 760 torr
Therefore you need to find the partial pressure of oxygen:
P(O2) = 760 torr -0.285 torr - 634.034 torr =130.013 torr

Humans might build drainage systems.
Humans might extract more water from the ground.
Human behavior does not change because of the water cycle.
Answer: Humans might extract more water from the ground.
Explanation:
Humans may face the situations of unavailability of water supply. Majority of the human population is dependent upon the source of water like oceans, lakes, rivers, ponds and wells for their water supply.
But in the scarcity of water from the drainage supply by the water body human population should search for a relevant alternative such as groundwater. Groundwater is the underground reservoir of water. The water in the groundwater reservoir accumulates from the sources such as rainfall, snow melting, river and oceanic water.
Humans should search for groundwater reservoir for compensating the scarcity of water.
