You are doing research on a space station located on Planet X. The temperature inside the space station is 21oC and the air pressure in the space station is 779 mm Hg. A balloon with a volume of 923 mL inside the space station floats out onto Planet X where the atmospheric pressure is 0.28 atm. The volume of the balloon changes to 3,492 mL. What is the temperature on planet X IN UNITS of oC? Remember that there are 760 mm Hg per 1 atm.
At 700 K the equilibrium constant for the reaction CCl4(g) C(s) + 2 Cl2(g) is Kp = 0.76. A flask is charged with 2.00 atm CCl4, which then reaches equilibrium at 700 K.
The original volume of a gas was 500 ml. When the pressure was decreased to 1.3 pascals, the volume increased to 700 ml. What was the original pressure?
