Question
1- The van der Waals equation for real gases recognizes that:
the non-zero volumes of gas particles effectively decrease the amount of "empty space" between them
2-
What is the root mean square speed of O2 at 298.3 K and 1.023 atm?
443 m/s
0.0349 g
4-A student finds an unlabeled 50.0 L gas tank and the regulator indicates that the tank pressure is 3.28 atm. If the gas tank is at room temperature (25.0 °C) and through subtraction the gas was found to weigh 255 g, what is the identity of the gas?
gas particles have non-zero volumes and interact with each otherExplanation / Answer
Ans 1 : All of these statements are true
The vander waal equation is in association with pV = nRT. It accounts for the attractive intermolecular forces between the gas particles and has two corrective factors a and b.
