Calculate the work in Joules when 2.5 mols of water vaporizes at 1 atmosphere pressure and 25 degrees C. The work is done in pushing back the atmosphere. Assume that the change in volume of the liquid water is negligible compared to that of the vapor.
a. 1.33 kiloJoules
b. 17.03 kiloJoules
c. 5.57 kiloJoules
d. 7.24 kiloJoules
e. 6.19 kiloJoules

Calculate the volume in mL of a 1.350 M HCI solution required to titrate the following solution.
A 50.0 mL sample of 0.55 M benzoic acid, C6H5COOH, a weak monoprotic acid, is titrated with 0.47 M NaOH. Calculate the pH at the equivalence point. Ka of C6H5COOH = 6.5 10-5
Suggest at least two reagents other than sodium borohydride that could be used to carry out the reduction of 9-fluorenone to 9-hydroxyfluorene.
A fixed quantity of gas at 24 C exhibits a pressure of 745 torr and occupies a volume of 4.40 L. Use Boyle's law to calculate the volume the gas will occupy if the pressure is increased to 1.88 atm while the temperature is held constant.
which of the following accounts for the unusually high boiling point of water? the density of water, the hydrogen bonds in water
In a second 50.00mL aliquot, the ClO4- was reduced to Cl- with V2(SO4)3. Titration of the reduced sample required 40.12mL of the AgNO3 solution. Calculate the %KCl and %KClO4 in the sample
