Unit 10 and 11 Practice

Front

What is the conclusion about the number of gas particles in Flask A (hydrogen) and Flask B (oxygen) at the same temperature and pressure?

Back

Flask A and B have equal particles.

Front

What does the kinetic molecular theory of gases state about gas particles?

Back

Gas particles are in constant random motion.

Front

What is the volume of 1 mole of an ideal gas at standard temperature and pressure (STP)?

Back

22.4 L

Front

What is the relationship between gas particle motion and temperature according to the kinetic molecular theory?

Back

Gas particles move faster at higher temperatures.

Front

If the partial pressure of Argon is 3 atm and the total pressure is 10 atm, what is the partial pressure of Krypton?

Back

7 atm.

Front

Define the kinetic molecular theory of gases.

Back

A theory that explains the behavior of gases in terms of particles in constant motion.

Front

What is the significance of STP in gas calculations?

Back

STP (Standard Temperature and Pressure) is used as a reference point for gas calculations, defined as 0°C (273.15 K) and 1 atm pressure.

Front

What is the formula for calculating the total pressure of a gas mixture?

Back

Total pressure = Sum of partial pressures of all gases in the mixture.

Front

What happens to the volume of a gas when the temperature increases, assuming pressure is constant?

Back

The volume of the gas increases (Charles's Law).

Front

What is the ideal gas law equation?

Back

PV = nRT, where P = pressure, V = volume, n = number of moles, R = ideal gas constant, T = temperature.
