Using the Combined Gas Law
An inflated balloon has a volume of 6.0 L at sea level (1.0 atm) and is allowed to ascend until the pressure is 0.45 atm. During ascent, the temperature of the gas falls from 22 °C to -21 °C. Calculate the volume of the balloon at its final altitude.
A 0.50-mol sample of oxygen gas is confined at 0 °C and 1.0 atm in a cylinder with a movable piston. The piston compresses the gas so that the final volume is half the initial volume and the final pressure is 2.2 atm. What is the final temperature of the gas in degrees Celsius?
Lecture #29 The beaker inside the pumpkin contains 200.0 mL of a 8.31M solution of hydrogen peroxide. If all of the hydrogen peroxide decomposes according to 2 H 2 2 q)→2 H O (2) + O (g2, what volume of oxygen gas (at 22.27 ºC and 0.8963 atm) will be generated REMEMBER PV=nRT (you should have that and what each letter means MEMORIZED) First question to ask yourself is Do I have all parts...
