What is the pressure of the gas in the flask when the levels of water in the buret and leveling bulb are equal?
Homework Answers
When the water levles are equal the pressure are equal. You will keep the water levles equal while running the reaction so that the pressure inside the reaction chamber and the buret is equal to atmospheric pressure.

Consider a situation in which a flask is half-filled with liquid water at room temperature. The partially filled flask is then sealed and given time to reach equilibrium. Which of the following statements are true? [Select all that apply.] After the flask reaches equilibrium, there will no longer be any movement of individual water molecules from the gas phase into the liquid phase. The rate of condensation decreases as the flask approaches equilibrium. The rate of condensation increases as the...
