The following shows 1.00L bulbs connected by valves. Each bulb contains neon gas with amounts proportional to the number of atoms pictorially reprsented in each chamber. All three bulbs are maintained at the same temperature. Unless stated otherwise, assume that the valves connecting champers are closed and seal the gases in their respective chambers. Assume also that the volume between chambers is negligible. B C If the pressure in bulb A is 2.00atm and the valves between the bulbs are opened, what is sum of Pa + Pb + Pc? Answer in atm, do not include units.

The following figure shows three 1.00-L bulbs connected by valves. Each bulb contains argon gas with amounts proportional to the number of circles pictorially represented in the chamber. All three bulbs are maintained at the same temperature. Unless stated otherwise, assume that the valves connecting the bulbs are closed and seal the gases in their respective chambers. Assume also that the volume between each bulb is negligible. (a) Which bulb has the highest pressure? (b) If the pressure in bulb A is 0.500 atm, what is the pressure in bulb C? (c) If the pressure in bulb A is 0.500 atm, what is the total pressure? (d) If the pressure in bulb A is 0.500 arm, and the valve between bulbs A and B is opened, redraw the figure shown above to accurately represent the gas atoms in all three bulbs. What is P A+P B+P C? Compare your answer in part (d) to that in part (c). (e) Follow the instructions of part (d) but now open only the valve between bulbs B and C.
An intermediate reaction used in the production of nitrogen-containing fertilizers is that between ammonia and oxygen: 4NH3(g)+5O2(g)4NO(g)+6H2O(g) A 150.0-L reaction chamber is charged with reactants to the following partial pressures at 500C: PNH3=1.3atm, PO2=1.5atm. What is the limiting reactant?
Consider a 5.00-L tank containing 375 g of Ar at a temperature of 25 C. (a) Calculate the pressure in the tank using both the ideal gas law and the van der Waals equation. (b) Which correction term, a(n/V)2 or bn, has the greatest influence on the pressure of this system?
Workers at a research station in the Antarctic collected a sample of air to test for airborne pollutants. They collected the sample in a 1.00-L container at 764 torr and 20 C. Calculate the pressure in the container when it was opened for analysis in a particulate-free clean room in a laboratory in South Carolina, at a temperature of 22 C.
The oxides of Group 2A metals (symbolized by M here) react with carbon dioxide according to the following reaction: MO(s)+CO2(g)MCO3(s) A 2.85-g sample containing only MgO and CuO is placed in a 3.00-L container. The container is filled with CO2 to a pressure of 740. torr at 20.C. After the reaction has gone to completion, the pressure inside the flask is 390. torr at 20.C. What is the mass percent of MgO in the mixture? Assume that only the MgO reacts with CO2.
Shown below are three containers of an ideal gas (A, B, and C), each equipped with a movable piston (assume that atmospheric pressure is 1.0 atm). a How do the pressures in these containers compare? b Are all the gases at the same temperature? If not, compare the temperatures. c If you cooled each of the containers in an ice-water bath to 0.0C, describe how the volumes and pressures of the gases in these containers would compare.
