A gas mixture containing 50 g of Helium (He), 120 g of Argon (Ar), and 0.1 g Carbon monoxide (CO), has a total pressure of 2560 mbar. (M Ar = 39.95 g/mol, M He = 4 g/mol, M CO = 28 g/mol) The gas mixture is used to reduce hematite (Fe2O3, M = 159.6 g/mol) to iron. State which of the gas constituents is expected to react with hematite, derive a chemical equation for this reaction, and determine the mol fraction of gas mixture required for...
1) a) The flue gas from a combustion process was found to contain 78% N2, 20% O2, 1.1% CO2 and 0.9% Ar. The gas was cooled to 298 K, pressurised to 2.0 x 105 Pa in the presence of water and allowed to come to equilibrium. Rank these gases in order from highest concentration to lowest concentration. The Henry’s Law constants for the gases at 298 K are: kH(N2) = 6.45 x 10^–9 mol L–1 Pa–1 kH(O2) = 1.34 x...
The ideal gas law describes the relationship among the volume of an ideal gas (V), its pressure (P), its absolute temperature (T), and number of moles (n): PV=nRT Under standard conditions, the ideal gas law does a good job of approximating these properties for any gas. However, the ideal gas law does not account for all the properties of real gases such as intermolecular attraction and molecular volume, which become more pronounced at low temperatures and high pressures. The van...
A gas mixture contains 0.150 mol of oxygen (O2) gas, 0.116mo lof nitrogen (N2) gas. and 0.211 mol of argon (Ar) gas in a 0.500L flask at 298K. What is the partial pressure of N2 the mixture?

What fraction of the total pressure in the flask is due to N2? c. If the temperature of the flask is lowered, what happens to the pressure inside the flask? d. On a molecular level, explain why the pressure changes as you predicted in part (c). e. If...
1. State whether the behavior of methylamine (CH,NH2) would be less ideal than that of argon. 2. Calculate the value of R in L-atm/mol-K by assuming that an ideal gas occupies 224 L/mol at STP Why do you equalize the water levels in the bottle and the beaker? 3.

A mixture of He, Ar, and Xe has a total pressure of 2.80 atm . The partial pressure of He is 0.300 atm , and the partial pressure of Ar is 0.300 atm . What is the partial pressure of Xe? A volume of 18.0 L contains a mixture of 0.250 mole N2 , 0.250 mole O2 , and an unknown quantity of He. The temperature of the mixture is 0 ∘C , and the total pressure is 1.00 atm...
Calculate the total pressure (in atm) of a mixture of 2.00 * 10^ -2 mol of helium, He, and 5.00 * 10^ -2 mol of oxygen, O2, in a 2.00 L flask at 20.°C. Assume ideal gas behavior.
If 96.5 mol of an ideal gas occupies 97.5 L at 93.00 °C, what is the pressure of the gas? Heliox is a helium-oxygen mixture that may be used in scuba tanks for divers working at great depths. It is also used medically as a breathing treatment. A 7.25-L tank holds helium gas at a pressure of 1563 psi. A second 7.25-L tank holds oxygen at a pressure of 415.6 psi. The two gases are mixed in a 7.25-L tank....
