Two flasks of equal volume and at the same temperature contain different gases. One flask contains 5.0 g of O₂ and theother flask contains 5.0 g of H₂. Is each of the following statements true or false? Explain. (8.1)b. The pressures in the flasks are the same.

Indicate which diagram (1, 2, or 3) represents the volume of the gas sample in a flexible container when each of the following changes (a to d) takes place: (8.2, 8.3)c.Atmospheric pressure decreases if temperature does notchange.

A balloon is filled with helium gas with a partial pressure of 1.00 atm and neon gas with a partial pressure of 0.50 atm. Foreach of the following changes (a to e) of the initial balloon, select the diagram (A, B, or C) that shows the final volume of the balloon: (8.2, 8.3, 8.6)d. The Kelvin temperature doubles and half of the gas atoms leak out (P does not change).

At a restaurant, a customer chokes on a piece of food. You put your arms around the person's waist and use your fists topush up on the person's abdomen, an action called the Heimlich maneuver. (8.2)b. Why does it cause the person to expel the food item from the airway?

At 100 °C, which of the following diagrams (1, 2, or 3) represents a gas sample that exerts the: (8.1)b. highest pressure??

Indicate which diagram (1, 2, or 3) represents the volume of the gas sample in a flexible container when each of the following changes (a to d) takes place: (8.2, 8.3)d. Doubling the atmospheric pressure and doubling the Kelvintemperature.
