What does the Law of Partial Pressures state?
The total pressure of a gas is equal to its density times its volume.
The volume of a gas is inversely proportional to its pressure.
The pressure of a gas mixture equals the sum of the pressures each gas would exert alone.
The pressure of a gas is directly proportional to its temperature.
What is the mole fraction symbol represented by?
Alpha (α)
Beta (β)
Gamma (γ)
Chi (χ)
How is the partial pressure of oxygen in air calculated?
By adding the pressures of all gases in the air
By multiplying the total atmospheric pressure by the mole fraction of oxygen
By subtracting the pressure of nitrogen from the total atmospheric pressure
By dividing the moles of oxygen by the total moles of air

Sodium acetate, carbon dioxide, and water are formed
No reaction occurs
Hydrochloric acid and sodium hydroxide are formed
Oxygen and hydrogen gases are released
What must be subtracted from the total pressure to find the pressure of the collected gas?
The vapor pressure of the water
The atmospheric pressure
The pressure of the container
The partial pressure of oxygen
How do you calculate the moles of gas collected in an experiment?
By measuring the gas's color
