Presentation transcript:

Chapter 5: 1. Which of the following is not a measurement of pressure? mm Hg torr atmosphere manometers

2. If the volume of a gas increases when the temperature and moles of gas are held constant, what will happen to the gas pressure? a. The pressure will also remain constant. b. The pressure will increase. c. The pressure will decrease. d. The pressure change depends on the chemical composition of the gas.

3. A balloon is inflated and then immersed in liquid nitrogen 3. A balloon is inflated and then immersed in liquid nitrogen. As the balloon cools, it shrinks in volume. Which gas law best describes this phenomenon? Charles’s law Boyle’s law Gay-Lussac’s law Avogadro’s law

4. If two ideal gases, A and B, are mixed together, what will be the final pressure of the mixture? the total pressure will be the difference between the partial pressure of A and the partial pressure of B the total pressure will be the sum of the partial pressures of A and B the total pressure will depend on the chemical identities of A and B the total pressure will be equal to whichever gas has the greater partial pressure

5. Which of the following equations correctly represents a method for determining the molar mass of an unknown gas using the ideal gas law? M = PV/gRT M = PV/RT M = gRT/PV M = nRT/PV

6. According to Henry’s law, if the partial pressure of a gas increases, what will happen to the amount of the gas dissolved in any liquid present? a. It will increase. b. It will decrease. c. It will remain constant. d. It will be eventually become 0.
