Using a flow diagram, show the separation of a mixture containing p-bromoacetanilide, N-cyclopentyl-N-methyl-N-propylamine (N mean the group is attached to the nitrogen of the amine and m-nitrophenol. Specify the organic solvent and aqueous solutions to be used for the separation. Provide the exact acid-base reaction that occurs during each step of the separation.
For the reaction Cu(s) + 2 Fe3+(aq) Cu2+(aq) + 2 Fe2+(aq), the equilibrium constant is Kc = 3.7×10^14 at 25 oC. Suppose that excess Cu(s) is added to 1.0 L of 0.015 mol L^-1 Fe(NO3)3(aq), with no change in volume. What is the equilibrium concent..
what is the maximum mass of CO2 that can be produced from the combustion of .377g C2H5OH
Determine the value of Kc for the following reaction if the equilibrium concentrations are as follows: [N2]eq = 3.6 M, [O2]eq = 4.1 M, [N2O]eq = 3.3 × 10-18 M.

Why does the absolute refractory period occur and What is happening in the cell.
How many grams of nitrogen monoxide are produced when copper metal reacts with nitric acid to form water and 5.92 g of copper(II) nitrate in addition to the nitrogen monoxide?
An experiment shows that a dry 113-mL gas sample of a pure gas has a mass of 0.171 g at a pressure of 721 mmHg and a temperature of 32.0 °C. What is the molar mass of the gas
what is the final mass upon mixing 8.54 mL of HCl and 8.54 mL of NaOH, both solutions have an initial concentration of 2.00 M.
A very long insulating cylindrical shell of radius 6.70cm carries charge of linear density 8.60Nc spread uniformly over its outer surface.
Free radicals are also important in many environmentally significant reactions. For example, photochemical smog, which forms as a result of the action of sunlight on air pollutants, is formed in part by the following two steps.
which of the following processes are at equilibrium? a)opposing rates of reaction are equal. b)the rate of the forward reaction is faster than the rate of the reverse reaction. c)concentrations of reactants and products do not change.
