Which chamber would perform better? Chamber (A) has 100 psi propane and 500 psi oxygen in one cubic inch. Chamber (B) has 100 psi propane and 500 psi oxygen plus 200 psi of Co2 in one cubic inch. Would the extra Co2 do anything for us? As in build more pressure?

2. Air is steadily discharged from a large chamber in which the pressure is 500 kPa, the temperature is 30°C, and the velocity is effectively zero through a nozzle, as shown in Fig. 2. Assuming one dimensional isentropic flow, find: (a) if the pressure at some section of the nozzle is 80 kPa, the Mach number, temperature, and velocity at this section. (b) if the nozzle has a circular cross-section with a diameter of 12 mm at the section discussed...

On a test at Microsoft, which has a mean of 500 and a standard deviation of 100, only the top 2% of the test takers will get an interview with Bill Gates. What score or better will they have to earn on this test to get the interview? Please show the work. I can use excel so if you could explain how to do it in there, that would be even better! :)

1) A mixture of oxygen and ammonia at 273.15 K and 1.00 atm has a volume of 150.0 cm .This mixture is cooled to the temperature of liquid nitrogen at which ammonia freezes out and the remaining gas is removed from the vessel. The vessel is allowed to warm to 273.15 K and 1 atm, and the volume is now 85.0 cm . Calculate the mole fraction of ammonia in the original mixture. 2) (a) Use the van der Waals...

For the video response portion of this assignment, your job will be to state what would happen to the oxygen bond to Hemoglobin if the pH of the tissue was the same as that of the lungs using the logic of the person’s presentation you watched. Discuss whether or not you agree with this. The video said this: Oxygen must be transported in the blood from the lungs, because the partial pressure of oxygen (pO2) is relatively high (approximately 100...

The partial pressure of oxygen in the lung alveoli is a bit lower than in ambient air, being about 100 mm of mercury, or 0.13 Atm (it is lower than the partial pressure in air mainly because oxygen is continually taken up by the alveolar capillaries and carbon dioxide is continually released into the alveoli). In cell-free blood plasma (or a saline solution formulated to match key characteristics of blood plasma), which lacks red blood cells and therefore lacks hemoglobin,...

General Chemistry II Part II. Fuel efficiency (6 pts) Fuel efficiency is the efficiency of the conversion of chemical energy contained in a fuel into work. Let's see which one of these fuels (hydrogen gas or liquid propane) will allow us to do more electrical work. Use the thermodynamic data provided to answer the following questions: 1. First determine the amount of heat released in direct combustion of (a) 1 mole of hydrogen gas; (b) 1 mole of liquid propane...
