Answer:
P(H₂) = 807.2 torr
Explanation:
According to the Dalton law, the pressure of mixture of a gas is sum of the partial pressure of its mixing component gases.
P(total) = P1 + P2 + P3 +....
In given problem,
Total pressure is = 794 torr
Partial pressure of water = 13.2 torr
Partial pressure of hydrogen = ?
Solution:
P(total) = P(H₂O) + P(H₂)
P(H₂) = P(total) - P(H₂O)
P(H₂) = 794 torr - 13.2 torr
P(H₂) = 807.2 torr
Answer : Option A) Deforestation.
Explanation : Factors related to deforestation can lead to desertification in presence of natural drought.
As natural drought hit area is an area which has low amount of water supply in the land. It is also called as below average precipitation land when drought area is deforested it will lead to desertification. As the plants in the drought area are the reason why their is at least low water is found, if these vegetation is deforested then it will lose its capacity to hold water and the land will be deserted.
