Problems in this set involve e ffusion and/or partial pressure. Several of the problems are repeats.
(Mm(SF 6) = 146.06 g/mol; Mm(UF6) = 352.02 g/mol; Mm(CH4) = 16.04 g/mol; and Mm(C2H6)=
30.07 g/mol.)

A sample contains an unknown ratio of methane, CH4,t o ethane,C2H6. This sample is placed into a first effusion apparatus and the effused gas is collected. This effused gas is placed into a second apparatus and allowed to effuse a second time. The mole percent of effused ethane proves to be 31.7%. What was the initial mole percent ethane? (num. ans. 46.4%)

A mixture of isobutylene (0.350 atm partial pressure at 500 K) and HCl(0.550 atm partial pressure...

A mixture of isobutylene (0.350 atm partial pressure at 500 K) and HCl(0.550 atm partial pressure at 500 K) is allowed to reach equilibrium at 500 K. What are the equilibrium partial pressures of tert-butyl chloride, isobutylene, and HCl? The equilibrium constant KpKp for the gas-phase thermal decomposition of tert-butyl chloride is 3.45 at 500 K: (CH3)3CCl(g)⇌(CH3)2C=CH2(g)+HCl(g)

If the total pressure is 1.07 atm, what is the partial pressure of Oxygen?

1.) Gas Number of moles N2 3.10 O2 0.76 CO2 0.12 If the total pressure is 1.07 atm, what is the partial pressure of Oxygen? (Your answer will be in atmospheres, but do NOT include units - Blackboard won't allow them. Use two decimal places, and simply give the number portion.) 2.) A reaction is carried out that produces hydrogen gas. The gas is collected in an inverted beaker over water at 25 oC. The vapor pressure of water at...

Explain what partial pressure is. List the partial pressures of O2 and CO2 in alveolar air and explain what determines their values (discuss each gas separately). List the partial pressures of O2 and CO2 in systemic arterial blood and explain what determines their values. List the partial pressures of O2 and CO2 in systemic venous blood and explain what determines their values.

Optimization problems are a common engineering task. Typically, these problems involve minimizing cost or maximizing profit. In this problem we are interested in determining the optimum amount of insulation to wrap around a steam supply pipe. The optimum amount is the one that produces the largest savings. Wrapping insulation around the pipe saves us money by reducing the amount of heat lost through the pipe (lower fuel bills). However, insulating the pipe costs money – we must buy and install...

The solubility of N2 in blood at 37 ° C and at a partial pressure of...

The solubility of N2 in blood at 37 ° C and at a partial pressure of 0.80 atm is 5.6 × 10−4 mol/L. A deep-sea diver breathes compressed air with the partial pressure of N2 equal to 5.3 atm. Assume that the total volume of blood in the body is 5.5 L. Calculate the amount of N2 gas released (in liters at 37 ° C and 1.00 atm) when the diver returns to the surface of the water, where the...

Eastern Manufacturing is involved with several situations that possibly involve contingencies

Problem 13-6 Various contingencies [LO13-5, 13-6] Eastern Manufacturing is involved with several situations that possibly involve contingencies. Each is described below. Eastern’s fiscal year ends December 31, and the 2018 financial statements are issued on March 15, 2019. Eastern is involved in a lawsuit resulting from a dispute with a supplier. On February 3, 2019, judgment was rendered against Eastern in the amount of $116 million plus interest, a total of $131 million. Eastern plans to appeal the judgment and...
