One mole of water vapor is expanded reversibly from 5L to 15L at a temperature of 800K. Calculate q, w, deltaE for this process assuming that water behaves as a van der Waals gas, making use of the formal relation
(partial E / partial V) at constant T = [ T*(partial P / partial T) at constant V ] - P.
Then repeat the calculations assuming ideal gas behavior
Arrange the following molecules in the expected order of increasing boiling points: carbon tetrabromide, CBr4; butane, CH3CH2CH2CH3; fluorine, F2
oxygen gas is collected over water at 21 degrees C and an atmosperic pressure of 748 mm Hg. What is the partial pressure of oxygen gas in the mixture
What are bonding theories? Why are they important? What may they be used for. HI has a force contents of 314 Nm^-1 and a bond length of 160.92 pm.
The solubility of N2 in blood at 37 oC and at a partial pressure of 0.80 atm is 5.6 X 10-4 mol/L. A deep-sea diver breathes compressed air with the partial pressure of N2 equal to 3.1 atm. Assume that the total volume of the blood in the body is 5..
