A balloon contains 0.1 moles of oxygen and 0.4 moles of nitrogen. If the balloon isat standard temperature and pressure,what is the partial pressure of the nitrogen? Solution Partial pressure is found byDalton's Law: Px= PTotal( nx/ nTotal) where Px= partial pressure of gas x PTotal= to...
Example: My refrigerator has a volume of 1,100 L. If the temperature inside the refrigerator is 3.0º C and the air pressure is 1.0 atm, how many moles of air are in my refrigerator? Chemistrivia The ideal gas law explains why hot air balloons work. The number of moles of air insid...
Example 3.6 Using the data in Example 3.5 and assuming real gas behavior, calculate the density of the gas phase under initial reservoir conditions. Compare the results with that of ideal gas behavior. Solution The table below describes the gas composition. ComponentyiMiyiMiTci (°R)yiTcipciyipc...
Homework Statement A cylinder fitted with a movable piston contains ideal gas at 27C, pressure .5 x 10^5 Pa, and volume 1.25 m^3. What will be the final...
For example, the migration of solvent within charged membranes, which normally occurs from high to low counterions’ concentrations, can be reversed by volumetric deformations of the membrane, contradicting our intuition based on osmosis23. Understanding the role of solution non-idealities on the ...
The piston is then allowed to slide freely, whereupon the gas in chamber 1 pushed the piston a distance “a” to equalize the pressure. Find a. Relevant Equations:: ##PV^\gamma =## constant I was puzzling over how to solve this and finally peeked at the solution. They used...
The proposed approach is free of stability problems which always plague space-time decoupled methods. A numerical example of closed end shock tube which combines simultaneous compression and rarefaction is presented at low Mach numbers. Applicability and effectiveness of the proposed formulation is ...
For example, when smaller rim angles of the primary mirror are required, problems with tracking and mechanical stability occur (Collares-Pereira et al., 1991; Benitez et al., 1997; Omer and Infield, 2000). In addition, some secondary-mirror designs are rather complex (Collares-Pereira et al...
I was so deeply indulged in my research that I forgot my meals and time. Now I have made great progress. Several of my research papers have been published. The methods proposed in my papers have been proven to be valuable for the solution of some problems. I am very happy. The ladder...
It’s vital to call an expert when you have electrical problems. Not doing so could be risky and expensive. Issues with switches can cause short circuits that can lead tohouse fires or electric shock. Therefore, if you think something is wrong with a switch, get help right away.Don’t tr...
