At 25 C the vapor pressure of water is 23.8Torr. If 10.02g of water is placed in a 3.00L flask at 25 C, will the water be completely gaseous, entirely liquid, or in both phases? If in both phases, find out the mole fraction in each phase.
When heated, cyclopropane is converted to propene. Rate constants for this reaction at 470 deg C and 510 deg C are k= 1.10 x 10^-4 and k2=1.02 x 10^-3. Determine the activation energy.
One hundred fifty kmol of an aqueous phosphoric acid solution contains 5.00 mole % H3PO4. The solution is concentrated by adding pure phosphoric acid at a rate of 20.0 L/min
Suppose that you developed your own new temperature scale, denoted oN. You chose 30.0oN as the temperature of freezing water and 280oN as the temperature of boiling water at 1.0 atm pressure.
Suppose you are given 150 mg of an unknown mixture that contains three compounds, and you are told to separate the compounds using column chromatography
Epsom salt is a hydrate with a formula MgsO4.xH2O, where x indicates the number of moles of H2O per mole of MgSO4. After a 1.687 g sample of the hydrate is heated, 0.824 of MgSO4 remains. How many molecule of water are present per formula unit of ..
consider separate 1.0-l samples of heg and uf6g both at 1.00 atm and containing the same number of moles. what ratio of
34.62mL of 0.1510M NaOH was needed to neutralize 50.0mL of an H2SO4 solution. What is the concentration of the original sulfuric acid solution?
Traces of toxic, man-made hexachlorohexanes in North Sea sediments were extracted by a known process and by a new procedure, and measured by chromatography.
their molecules or ions are in close contact and do not move. a change of state or phase transition is a change of a
Compare the properties of elements and compounds. Give two examples of each, including one example that exists in the human body. Explain the atomic nature of one element and one compound found in human body.
Calculate the pH of the solution after the addition of 100mL of 1.00 M HCL. the Ka for Hf is 3.5*10-4
