LAPIOL PEDOU STOPAD 2. Each student has been assigned a common gas or volatile liquid compound. (A) Do you expect the compound you have been assigned behave like an ideal gas at standard temperature and pressure? (This can be quantified by comparing the pressure of the compound using the Van der Waals equation of state to that of the ideal gas equation of state). The Van der Waals equation of state is one of the most common used to understand...

You want to store 150. g of gas in a 14.8-L tank at room temperature (25 °C). Calculate the pressure the gas would have using the ideal gas law and the van der Waals equation. (For , co2 a= 3.59L/mol and b=0.0427 L/mol .)

Pre-Laboratory Questions for Lab 10 1. The ideal gas law is an equation used for examining ideal gases. The four tenets of kinetic molecular theory define what an ideal gas is. However, no ideal gases exist in nature, only real gases do. Van der Waals' equation attempts to make corrections to real gases that do not exhibit ideal behavior. Two gases are given below that do not exhibit ideal behavior. Explain for each one why it doesn't exhibit ideal behavior....

The ideal gas law describes the relationship among the volume of an ideal gas (V), its pressure (P), its absolute temperature (T), and number of moles (n): PV=nRT Under standard conditions, the ideal gas law does a good job of approximating these properties for any gas. However, the ideal gas law does not account for all the properties of real gases such as intermolecular attraction and molecular volume, which become more pronounced at low temperatures and high pressures. The van...
