The atmosphere of the planet Mars is 95.3% carbon dioxide, 2.6% nitrogen, 1.9% argon, with the remaining fraction being traces o

kodGreya [7K]

Answer:

Mean Partial pressure of Nitrogen in Mars' atmosphere = 15.86 Pa

Explanation:

According to Dalton's law of Partial Pressure, the total pressure exerted by a mixture of ideal gases (that do not react together) is the sum of the partial pressures of the individual gases that make up the mixture. It goes further to explain that the partial pressure of a gas in a mixture of gases is equal to its mole fraction of that gas multipled by the total pressure exerted by the mixture of gases.

Total Pressure exerted by the mixture of gases in the atmosphere on Mars = Mean atmospheric pressure on Mars = 610 Pa

Partial pressure of Nitrogen = (mole fraction or mole percentage of Nitrogen in the atmosphere) × (total pressure exerted by all the gases in the atmosphere)

Mole percentage of Nitrogen in the atmosphere of Mars = 2.6%

Partial pressure of Nitrogen = 2.6% × 610 = 15.86 Pa

Mean Partial pressure of Nitrogen in Mars' atmosphere = 15.86 Pa

The force of attraction between a divalent cation and a divalent anion is 1.64 x 10-8 N. If the ionic radius of the cation is 0.

Elden [556K]

The radius of the anion is 7.413 nm

<h3>How to calculate the force of attraction between charges</h3>

The force of attraction (F) is given by the formula:

F = (1/4π∈r²)(Zc*e)(Za*e)

where:

∈ = permittivity of free space = 8.85*10⁻¹⁵ F/m

Zc = charge on the cation = +2

Zc = charge on the anion = -2

e = charge on an electron = 1.602 * 10⁻¹⁹ C

r = interionic distance

r = rc + ra

where rc and ra are the radius of the cation and anion respectively

F = 1.64 * 10⁻⁸ N

Therefore based on the equation of force of attraction:

1.64 *10⁻⁸ = [1/4π(8.85*10⁻¹⁵)r²](2 * 1.602*10⁻¹⁹)²

r² = 5.63 * 10⁻¹⁷

r = 7.50 nm

Since r = rc + ra

where rc = 0.087 nm

thus, ra = r - rc = 7.50 - 0.087

ra = 7.413 nm

Therefore, the radius of the anion is 7.413 nm

A vegetable garden is 12 meters long by 7 meters wide. It is home 168 mice. What is the population of the mice.

kotegsom [21]

Hello there!

A vegetable garden is 12 meters long by 7 meters wide. It is home 168 mice. What is the population of the mice.

The size of the vegetable garden is just extra information.

The only information we need is: "It is home 168 mice"

This means the population of mice is 168. Meaning, there are 168 mice living there.

I hope I helped!

Let me know if you need anything else!
