Recall the balloon race demo.

a. Imagine the pink balloon is filled with 2.0 L of dry Argon gas, while the yellow balloon is filled with 1.0 L of the same gas, at the same temperature. After the stopcock is opened, which balloon will lose half of its content more quickly? Why?

b. Now instead, imagine to have two balloons inflated with 1.0 mol of helium each. One is placed in liquid nitrogen, while the other is at room temperature. Which one will lose half of its content more quickly? Why?

c. Finally, let’s consider the scenario in which the pink balloon contains 5.0 mol of Helium, while the yellow balloon contains 0.1 mol of Xenon. Which one will lose half of its content more quickly?

Homework Answers

Answer #1

a) pink balloon will lose half of its content due to pressure or concentration.As no, of molecules increases the collision between the molecules and walls of balloon increases hence pressure increases and depletes fast.

b) The balloon at room temperatures will deplete fast as rate of diffusion is directly praportional to temperature. Beause liquid Nitrogen temp.is -196 C.

c) Pink balloon will lose half of its content quickly, because rate of diffusion is inversely praportional to molecular wt. He is lighter in weight than Xenon.

Chapter 5- Gases 24. As weather balloons rise from the earth's surface, the pressure of th atmosphere becomes less, tending to cause the volume of the balloons to exand. However, the temperature is much lower in the upper atmosphere that at sea level. Would this temperature effect tend to make such a balloon expand or contract? Weather balloons do, in fact, expand as they rise. What does this tell you? 37. Freon-12 (CF2Cl2) is commonly used as the refrigerant in...

Below is the background info for the lab assignment. The 4 blank boxes are the questions I would like answers too. The end point for the fine titration was 35.90 mL in the burette when the solution turned bright green again. And the coarse titration I got 35.36mL as the end point. 35.9 mL is exact in case you need that info. Thanks!
