If O2(g) and H2(g) are in separate containers of equal pressure, volume and temperature, which one of these statements is true? The amount of moles in the O2 container is greater than that in the H2 container. There are more molecules in the H2 container than molecules in the O2 container. If you increase the pressure in both containers, but keep temperature constant, the volume of both containers will increase If you increase the pressure in both containers, but keep...

4) Two containers of equal volume each hold samples of the same ideal gas. Container A has twice as many molecules as container B. If the gas pressure is the same in the two containers, the correct statement regarding the absolute temperatures TA and TB in containers A and B, respectively, is A) TA- JIB B) TA =TB. C) TA = 2TB. D) TA = TB. E) TA=TB:

A researcher wishes to use two identical containers (i.e. having the same volume), one to store 5 moles of O2 gas, and one to store 3 moles of N2 gas. Both are kept at 300 K and 5 atm. Is this possible? O Yes, since O2 and N2 have different molar masses. O Yes, since these conditions are not at STP. O Yes, since gases can be compressed. O No, because number of moles and temperature are directly proportional. No,...
