Trouton's rule states that the entropy of vaporization of nanopolar liquid is 88 JK-1 mol-1.. the normal boiling point of 1-octene is 121.3 C and its melting point is -101.73 C determine the enthalpy of vaporization of this compound.
Calculate the pH after 15.0 mL of 0.40M HCL is added to 20.0 mL of 0.50 M NH3 (Kb NH3= 1.8 x 10^-5)
Suppose you take a 25.00 mL sample of this hydrochloric acid solution. You then titrate it with a 0.1477 M sodium hydroxide solution.
If you wanted to adapt this procedure to prepare the analogous propoxy compound, how much propyl iodide would you have to use to carry out the reaction on the same scale?
NH3 is a weak base (Kb = 1.8 × 10-5) and so the salt NH4Cl acts as a weak acid. What is the pH of a solution that is 0.049 M in NH4Cl
Calculate the mass of KClO3 decomposed. The vapor pressure of water at 28 °C is 28.3 mmHg. (Hint: The gases collected are a mixture of oxygen and water vapor
What is the concentration of a solution formed by diluting 25.0 mL of a 3.2 M NaCl solution to 135.0 mL.
Explain the effect of the following experimental errors on your results: a) You add hexane to the reaction flask instead of 1-hexene b) You use 3% hydrogen peroxide instead of 30% c) You forget to add potassium carbonate in the seperation step.
Cinnamon owes its flavor and odor to cinnamaldehyde (C9H8O). Determine the boiling point elevation of a solution of 89.3 mg of cinnamaldehyde dissolved in 1.00 g of carbon tetrachloride (kb = 5.03 C/m)
Confirm whether an acid base reaction occurred stoichiometrically. The concentration of concentrated nitric acid is 15.8 M. For full credit show all calculations.
