(a)
Interpretation:
The flowrate of the gas stream leaving the condenser should be calculated
Concept introduction:
It is given that a gas stream contains 18 mole% hexane (rest is nitrogen), this stream is passed through a condenser where some of the hexane is liquefied. The stream properties are given as,
The hexane mole fraction of gas stream leaving the condenser is 0.05 while the liquid condensate is recovered at 1.5 L/min.
Material balance at steady state is,

Interpretation:
The percentage of hexane recovered as the liquid should be calculated.

Two bulbs are connected by a stopcock. The 7.50 L bulb contains nitric oxide (NO) at a pressure of 0.340 bar, and the 2.50 L bulb contains oxygen (O,) at a pressure of 0.510 bar. 02 ON After the stopcock is opened, the gases mix and react to produce nitrogen dioxide (CON) 2 NO(g) + 0,(g) – 2 NO,(g) Considering that the volume remains unchanged during the experiment, how does the total pressure in the bulbs change if the reaction is allowed to go to completion? The total pressure will remain constant. O There is not enough information to determine how the total pressure will change. O The total pressure will decrease. O The total pressure will increase.

- One type of gas mixture used in anesthesiologyis a 50%/50% mixture (by volume) of nitrous oxide (N2O) and oxygen(O2), which can be premixed and kept in a cylinder for later use.Because these two gases don’t react chemically at or below 2000 psi, attypical room temperatures they form a homogeneous single gas phase,which can be considered an ideal gas. If the temperature drops below-6C, however, N2O may begin to condense out of the gas phase. Thenany gas removed from the cylinder will initially be nearly pure O2; asthe cylinder empties, the proportion of O2 will decrease until the gascoming from the cylinder is nearly pure N2O. In another test, the valve of a 500 L cylinder full of the gas mixture at 2000 psi (gauge pressure) is opened wide so that the gas rushes out of the cylinder very rapidly. Why might some N2O condense during this process? (a) This is an isochoric process in which the pressure decreases, so the temperature also decreases.

Because these two gases don't react chemically at or below 2000 psi, at typical room temperatures they form a homogeneous single gas phase, which can be considered an ideal gas. If the temperature drops below -6° C, however, N2O may begin to condense out of the gas phase. Then any gas removed from the cylinder will initially be nearly pure O2; as the cylinder empties, the proportion of O2 will decrease until the gas coming from the cylinder is nearly pure N2O.

- Upon an experimental process, a round-bottomed glass flask (evacuated) weighs 62.0 g when its empty. In the following step, this flask was fulfilled with a liquid (d: 0.98g/mL) and weighs 160.0 g. The same flask used again in another experiment and weighs 62.5 g when fulfilled with an ideal gas (experimental conditions: 760mmHg and 300K) According to this data, calculate the molecular weight of the ideal gas.arrow_forwardA sample of unknown gas was heated to 125°C in a round bottom flask at standard pressure (1.00 atm), and its weight in a 100 ml round bottom flask was taken to be 30.098g. The round bottom flask weighs 30.0g. The gas was determined to be pure so that it can only be composed of a single element (N2, O2, F2, He, Ne, Ar, P2, S2, Cl2). Identify the gas.arrow_forwardP1A.6 The molar mass of a newly synthesized fluorocarbon was measured in a gas microbalance. is device consists of a glass bulb forming one end of a beam, the whole surrounded by a closed container. e beam is pivoted, and the balance point is attained by raising the pressure of gas in the container, so increasing the buoyancy of the enclosed bulb. In one experiment, the balance point was reached when the fluorocarbon pressure was 327.10Torr; for the same setting of the pivot, a balance was reached when CHF3 (M = 70.014 g mol−1) was introduced at 423.22 Torr. A repeat of the experiment with a di erent setting of the pivot required a pressure of 293.22 Torr of the uorocarbon and 427.22 Torr of the CHF3. What is the molar mass of the fluorocarbon?
