- An ideal gas is contained in a cylinder with a volume of 5.0 102 mL at a temperature of 30.C and a pressure of 710. torr. The gas is then compressed to a volume of 25 mL, and the temperature is raised to 820.C. What is the new pressure of the gas?arrow_forwardA typical barometric pressure in Redding. California, is about 750 mm Hg. Calculate this pressure in atm and kPa.arrow_forwardConsider two different containers, each filled with 2 moles of Ne(g). One of the containers is rigid and has constant volume. The other container is flexible (like a balloon) and is capable of changing its volume to keep the extemal pressure and internal pressure equal to each other. If you raise the temperature in both containers, what happens to the pressure and density of the gas inside each container? Assume a constant extemal pressure.arrow_forward
- A sample of a compound of xenon and fluorine was confined in a bulb with a pressure of 18 tor. Hydrogen was added to the bulb until the pressure was 72 torr. Passage of an electric spark through the mixture produced Xe and HF. After the HF was removed by reaction with solid KOH, the final pressure of xenon and unreacted hydrogen in the bulb was 36 torr. What is the empirical formula of the xenon fluoride in the original sample? (Note: Xenon fluorides contain only one xenon atom per molecule.)arrow_forwardWhen hydrogen peroxide decomposes, oxygen is produced: 2H2O2(aq)2H2O+O2(g)What volume of oxygen gas at 25C and 1.00 atm is produced from the decomposition of 25.00 mL of a 30.0% (by mass) solution of hydrogen peroxide (d=1.05g/mL)?arrow_forwardConsider the following sketch. Each square in bulb A represents a mole of atoms X. Each circle in bulb B represents a mole of atoms Y. The bulbs have the same volume, and the temperature is kept constant. When the valve is opened, atoms of X react with atoms of Y according to the following equation: 2X(g)+Y(g)X2Y(g)The gaseous product is represented as and each represents one mole of product. (a) IfP A=2.0 atm, what is P8 before the valve is opened and the reaction is allowed to occur? What is P A+P B? (b) Redraw the sketch to represent what happens after the valve is opened. (c) What is PA? What is PB? What is P A+P B? Compare your answer with the answer in part (a).arrow_forward
