Question- Part- 1- Three gases (8.00 g of methane, CH4, 18.0 g of ethane, C2H6, and an unknown amount of propane, C3H8) were added to the same 10.0-L container. At 23oC, the total pressure in the container is 5.50atm. Calculate the partial pressure of each gas in the container.
2- A gaseous mixture of O2 and N2 contains 40.8% nitrogen by mass. What is the partial pressure of oxygen in the mixture if the total pressure is 605mmHg ?
As much detail as probable is really appreciated
If the catalyst pore size is small in comparison with the mean free path, collisions with the pore wall controls the process'. The diffusivity under this condition is called 'Knudsen diffusivity'
1) there is a 621mL sample of O2 at 25 degree C. What is the volume at -25 degree C? 2) there are 5.22L of N2 at 13 degree C. What temperature is needed to expand the gas to 6.22L
the addition of anhydrous calcium chloride to the crude product obtained from the separation procedure often results in
Table salt (NaCl) and sugar (C12H22O11) are accidently mixed. A 5.00 g sample of the mixture is combusted, and 1.80 grams of CO2 are produced. What is the mass percent of sugar in the mixture
Lakes that have been acidified by acid rain can be neutralized by liming, the addition of limestone (CaCO3). How much limestone (in kg) is required to completely neutralize a 4.3 billion liter lake with a pH of 5.5?
it is not practical to count individual atomsmolecules because of their small size. however we can determine the number
Explain the temperature of the stratosphere is -23.0ºC as well as the pressure due to the zone is 1.4 x10-7 atm. Compute the number of ozone molecules present in 1.00 m3 (1L = 10-3 m3) in the stratosphere.
Draw the major organic product from reaction of 1-butyne with NaNH2, then CH3Br. If no reaction occurs, write ethane, CH3CH3.
Question- If groundwater with alkalinity of (4x10^-3) equiv (L^-1) and PH=7.5 is pumped to the surface and exposed to atmosphere, how would its composition change
Find the standard enthalpy of formation of ethylene, C2H4(g), given the following data: heat of combustion of C2H4(g) = -1411 kJ/mol; ?H°f[CO2(g)] = -393.5 kJ/mol; ?H°f[H2O(l)] = -285.8 kJ/mol.
sulfuric acid h2so4 is produced from water vapor sulfur dioxide and oxygen gas. write a balanced equation then
Nitrogen dioxide (NO2) cannot be contained in a pure form in the gas phase because it exists as mixture of NO2 and N2O4. At 25°C and 0.98 atm, the density of this gas mixture is 2.4 g/L. What is the partial pressure of each gas
