The pressure of a 1-L nitrogen gas sample at 25 ⁰C is 0.30 atm. The pressure of a 1-L oxygen gas sample at the same temperature
ki77a [65]

Answer:

Nitrogen = 0.3 atm

Oxygen = 0.25 atm

Argon  = 0.45 atm

Explanation:

According to Dalton's law of partial pressure, the total pressure in the container is equal to sum of the partial pressures of the individual gases.

Given;

Total pressure of the gases, P_total = 1 atm

Pressure of nitrogen, P_nitrogen = 0.3 atm

Pressure of oxygen, P_oxygen = 0.25 atm

Pressure of argon, P_argon = ?

P_{total} = P_{nitrogen} + P_{oxygen} + P_{argon}\\\\1 \ atm= 0.3 \ atm + 0.25 \ atm + P_{argon}\\\\1 \ atm= 0.55 \ atm +  P_{argon}\\\\ P_{argon} = 1 \ atm - 0.55 \ atm\\\\ P_{argon} = 0.45 \ atm

Therefore, the contribution of each gas to the total pressure of the gas mixture is;

Nitrogen = 0.3 atm

Oxygen = 0.25 atm

Argon  = 0.45 atm

C) landslides.

Explanation:

Landslides is not a way in which mountains are built on earth. It is a destructive process in nature that causes the slumping and wasting of land masses.

Landslide is a form of mass wasting and does no build masses.

Volcanoes helps to build mountains on the crust and this way, igneous rocks are formed.

Deposition process upbuilds to form sedimentary rocks.

Faulting is a can also be a constructive process that builds a mountain in the case of horsts and graben
