Challenge Air is a mixture of gases. By percentage, it is roughly 78 percent nitrogen, 21 percent oxygen, and 1 percent argon. (

There are trace amounts of many other gases in air. If the atmospheric pressure is 760 mmHg, what are the partial pressures of nitrogen, oxygen, and argon in the atmosphere?

The partial pressures of gases in air at 760 mmHg are N₂ (592.8 mmHg), O₂ (159.6 mmHg) and Ar (7.6 mmHg).

<h3>What is partial pressure?</h3>

Partial pressure is the pressure of a gas in a mixture of gases.

Air is a mixture of gases with 78% N₂, 21% O₂, 1% Ar and other gases in trace amounts. The partial pressure of a gas is proportional to its percentage.

Let's calculate the partial pressures of these gases, considering that the atmospheric pressure is 760 mmHg.

pN₂ = 760 mmHg × 78% = 592.8 mmHg

pO₂ = 760 mmHg × 21% = 159.6 mmHg

pAr = 760 mmHg × 1% = 7.6 mmHg

The partial pressures of gases in air at 760 mmHg are N₂ (592.8 mmHg), O₂ (159.6 mmHg) and Ar (7.6 mmHg).

The molecular geometry of SO 3 is a tetrahedral b. bent Coctahedral d. trigonal planar pyramidal
Dimas [21]

Answer:

The correct option is: d. trigonal planar              

Explanation:

Sulfur trioxide is a chemical compound and the chemical formula of the compound is SO₃. In this molecule, the sulfur atom is in its +6 oxidation state and is covalently bound to three oxygen atoms. Sulfur trioxide is a neutral molecule. According to the VSEPR theory, Sulfur trioxide has a<u> trigonal planar molecular geometry.</u>

How many moles are there in 77.1 g of cl2?
natita [175]
There are 70.90g of Cl2 in 1 mol (because 35.45g Cl in one mol). So 77.1g/70.9g≈1.0874 mol.
