The air at the top of Mount Everest has pressures of 201.0 torr N2, 50.0 torr O2, 2.0 torr Ar, and 0.5 torr CO2. What is the tot
nordsb [41]

Answer:

The total air pressure at the top of the highest peak in the world is 253.5 torr

Explanation:

The partial pressures of the gases present at the top of Mount Everest are;

Nitrogen, N₂ = 201.0 torr

Oxygen, O₂ = 50.0 torr

Argon, Ar = 2.0 torr

Carbon dioxide, CO₂ = 0.5 torr

By Dalton's law of partial pressure, the total pressure that a mixture of gases exerts is equal to the sum of the partial pressures of the individual gases

Mathematically, the law can be expressed as follows;

Total pressure, P = ∑P_i = P₁ + P₂ + · · ·

From which we have;

The total air pressure at the top of the highest peak in the world, Mount Everest, P_{Total Mont Everest} = The sum of the partial pressures of N₂, O₂, Ar, and CO₂

P_{Total Mont Everest} = 201.0 torr + 50.0 torr + 2.0 torr + 0.5 torr = 253.5 torr

P_{Total Mont Everest} = 253.5 torr = 0.33355263 atmosphere

Therefore, the total air pressure at the top of the highest peak in the world,  P_{Total Mont Everest} = 253.5 torr

A photocopier is making reduced copies of a photo that measures 25 centimeters in height. The height of the first copy is​ 80% o
Marat540 [252]

Answer:The height of First Copy is 20 cm.

Step-by-step explanation:

Given:

Original Height = 25 cm

First copy is reduce to 80% of Original height.

Therefore to find the height of first copy can be find out by multiplying 80 with original height and then dividing by 100.

∴ Height of First Copy =

Hence Height of first copy is 20 cm

Now Another copy is reduce to 85% of First Copy.

Therefore to find the height of another copy can be find out by multiplying 85 with first copy height and then dividing by 100.

∴ Height of Another Copy =

Hence Height of Another copy is 17 cm

What function is most affected if the sepal of a flower is damaged by air pollution?
stepladder [879]

Answer:answer in explanation try to understand dear

Explanation:Air pollutants have a negative impact on plant growth, primarily through interfering with resource accumulation. Once leaves are in close contact with the atmosphere, many air pollutants, such as O3 and NOx, affect the metabolic function of the leaves and interfere with net carbon fixation by the plant canopy.
