A rigid 8.20 L flask contains a mixture of H: gas, O; gas, and Ar gas. Within the flask, there are 2.50 moles of H2, and 2.0 atm of O2 gas, and sufficient Ar so that the partial pressure of Ar in the flask is 2.00 atm as well. The temperature of the gas mixture is 127°C. i. Calculate the pressure the H: gas produces. ii. Calculate the total pressure of the container that all 3 gases exert.

61 As one step in its purification, nickel metal reacts with carbon monoxide to form a compound called nickel tetracarbonyl, Ni(CO)4, which is a gas at temperature above about 316 K. A 2.000-L flask is filled with CO gas to a pressure of 748 torr at 350.0 K, and then 5.00 g of Ni is added. If the reaction describe occurs and goes to completion at constant temperature, what will the final pressure in the falsk be?
