A sample of 1.00 mol of a perfect monatomic gas with a molar heat capacity at constant volume of 3/2R initially at 298K and 10 L is expanded with the surroundings maintained at 298K, to a final volume of 20 L in three ways: a) isothermally and reversibly b) isothermally against a constant external pressure 0.50 atm c) adiabatically against a constant external pressure of 0.50 atm. Calculate /delta S, /delta H and /delta T for each path where the data permits.
When dealing with ICE tables and calculating Kb and such, how do you do the algebra to calculate x when x is NOT negligible?
If one reacts a double bond with bromine in chloroform a dibromide is obtained. However, if one reacts bromine in water with a double bond, a vicinal halohydrin is formed. Provide an explanation for this result and show a mechanism for the reactio..
