Which flask contains the largest number of molecules? O flask A flask B flask C O All contain same number of molecules. Submit Request Answer
Three identical flasks contain three different gases at standard temperature and pressure. Flask A contains C4H10, flask B contains SO2, and flask C contains He. Which flask contains the largest number of molecules?
Consider two 1 L flasks, one containing O2, the other containing He, each at STP. Which one of the following statements is false regarding these gases? O Each flask contains the same number of atoms or molecules. O The gases in each flask have the same average kinetic energy O The gases in each flask have the same density. O The pressure in each flask is the same O The temperature of the gases in each fask is 273.15 K
For questions 2 to 4 d, consider two 2.00 L flasks, one of which contains 0.250 mole of O2 gas at 50.0 deg C and the other of which contains 0.500 mole of H2 gas at 50.0 deg C. 4. a. In which flask is the ratio of molecular volume (volume occupied by the molecules touching one another in a condensed state) to gaseous sample volume (volume occupied by the entire gaseous sample) greater? (2 pt) b. ...
Be sure to answer all parts. Three 8−L flasks, fixed with pressure gauges and small valves, each contain 5 g of gas at 273 K. Flask A contains He, flask B contains H2, and flask C contains CH4. Rank the flask contents in terms of: (a) pressure. A > B > C A > C > B B > C > A B > A > C C > B > A C > A > B A = B...

I just need help with #4 in the photo thanks! Use the following to answer questions 3-4: Four identical 1.0-L flasks contain the gases He, C1, CH, and NH,, each at 0°C and 1 atm pressure. 3. For which gas are the molecules diatomic? A) He B) CI, C) CH, D) NHÀ E) all gases the same 4. Which gas has the highest density? A) He B) CI C) CH. D) NHÀ E) all gases the same
You have two flasks of equal volume. Flask A contains hydrogen gas (H2) at 0°C and 1 atm of pressure. Flask B contains CO2 gas at 25°C and 2 atm pressure. a) What is the ratio of the average kinetic energy per molecule of H2/CO2? b) What is the ratio of the average kinetic velocity of H2/CO2 molecules? c) What is the ratio of the number of molecules of CO2/H2? d) What is the mass ratio of CO2/H2?
three 6-L flasks filled with pressure gauges and small valves each contain 2 g of gas at 268K. Flask A contains H2 flask B contains CH4 and flask C contains He. Rank the flask contents in terms of : pressure average molecular kinetic energy diffusion rate after valve is opened total kinetic energy of the molecules density collision frequency (please do in form of A>B>C)
