At 298 K and 1 atm, the (delta H vap) and (delta Svap) of PCl(l) equal 32.7kj mol^- 1 respectively. By determing deltaGva, expalin why PCl(l) does not biol under these conditions.
a) calculate the normal boiling point of Pcl(l).
b) determine the vapour pressure of PCl3 (l) at 298K.
What is the electron geometry. 3. What is the molecular geometry. 4. What are the hybridized orbitals. 5. Is the molecule polar or non-polar
Suppose the calorimeter for this experiment had been made of a heat-conducting material (such as metal) rather than plastic foam, so that the portion of heat energy lost to the calorimeter itself was larger and could not be ignored
calculate the total heat (in J) needed to convert 20.0g ice at -8.00 c to liquid water at 0.600c? melting point at 1 atm
What volume (in mL) of water must be added to a 1.96 M solution of potassium hydroxide to make a 50.8 mL of a 0.625 M solution? Assume the volumes are additive.
The gas and the liquid have specific heats of 117.2 J/mol K and 72.3 J/mol K. How much heat is evolved when 20.0 g of CCl2F2 is cooled from +40 C to -40 C?
Consider the titration of 40.0 mL of 0.050 M of the fully protonated form of tryptophan with 0.10 M KOH. Calculate the pH of the solution at the following points
A graduated cylinder contains 131 mL of water. A 18.0 g piece of iron (density = 7.86 rm{g/cm^3}) and a 25.0 g piece of lead are added.
change in heat content we write h hfinal - hinitial or for chemical reactions h hproducts - hreactants given this
Designing and preparing aqueous buffer solution with the pH indicated.
A fixed quantity of gas at 21 exhibits a pressure of 730 and occupies a volume of 4.40. Use Boyle's law to calculate the volume the gas will occupy if the pressure is increased to 1.85 while the temperature is held constant.
