Question

select all the statements about gas solutions that are correct.
□ gases particles can easily mix because of the large space between the particles.
□ the amount of each gas present is proportional to each gas’s individual pressure.
□ the pressure of the gas solution is the sum of the pressures of each gas in the solution.
□ gases particles can easily mix because according to the kinetic molecular there are no intermolecular attractive forces.
□ gases will mix in any proportion.

Explanation:

1. First statement: Gas particles have large spaces between them, allowing easy mixing. Correct.
2. Second statement: By Dalton's law and mole fraction concepts, the amount (moles) of a gas in a mixture is proportional to its partial pressure (individual pressure in the mixture). Correct.
3. Third statement: The total pressure of a gas solution (mixture) is the sum of the partial pressures of each gas (Dalton's Law of Partial Pressures). Correct.
4. Fourth statement: The Kinetic Molecular Theory states that gas particles have negligible intermolecular attractive forces, so they mix easily. Correct (assuming "Kinetic Molecular" is a typo for "Kinetic Molecular Theory").
5. Fifth statement: Gases are miscible and can mix in any proportion because of their particle properties (large spaces, negligible intermolecular forces). Correct.

Answer:

• Gases particles can easily mix because of the large space between the particles.
• The amount of each gas present is proportional to each gas’s individual pressure.
• The pressure of the gas solution is the sum of the pressures of each gas in the solution.
• Gases particles can easily mix because according to the Kinetic Molecular [Theory] there are no intermolecular attractive forces.
• Gases will mix in any proportion.
