The reaction of an equimolar mixture of isopentyl alcohol also acetic acid will produce, at most 67% of the theoretical amount of isopentyl acetate. Confirm this with an equilibrium constant computation using K=4.2
calculate the maximum volume in mL of .15 M HCl that each of the following antacid formations would be expected to neutralize. Assume complete neutralization.
A 10.0-mL solution of .510 M NH3 is titrated with a .170 M HCl solution. Calculate the pH after the following additions of the HCl solution.
The destruction of the ozone layer by chlorofluorocarbons (CFCs) can be described by the following reactions: ClO(g) + O3(g) ----> Cl(g) + 2 O2(g) (ΔHrxn = -29.90 kJ)
How do the strengths of London forces compare in CO2 and CS2? Which of these is expected to have a higher boiling point?
a student titrates 50.0ml of apple juice and reports the following in the titration to the phenolphthalein end point with 0.1011 M NaOH.
At 25 degrees Celsius, the reaction: H3O+ + NH3 --> NH+ + OH- is first order in each reactant, and has a rate constant of 4.3x 10^10 M^-1 s^-1
Come up with a practical use for Prep-GC coupled with IR spectroscopy. Hint: if you can't identify your compound and you have a large peak above 3000 cm^-1, then think of a very common liquid that has OH's.
calculate the ionization energy of xenon , given that the energy of a photon of this light is 1.95 x 10^18 J (I calculated that from the given wavelength of 102 nm). now how do i calculate the ionization energy in kJ/mol for xenon
The equation for the complete combustion of ethene (C2H4) is C2H4(g) + 3 O2(g) ==> 2CO2(g) + 2H2O(g) If 2.70 mol C2H4 is reacted with 6.30 mole O2,
