Show that using many small volumes of organic solvent in an extraction from an aqueous phase is more effective than using fewer, larger volumes. Assume that the amount of material to extract, the total volume of organic solvent available, the aqueous phase volume and the distribution constant are all the same. Do this numerically or analytically.
Since there isn't an oxygen or some other electronegative atom in the molecule I'm not sure which peaks are which.
A 1.17 g sample of an alkane hydrocarbon gas occupies a volume of 674 mL at 28°C and 741 mmHg. Alkanes are known to have the general formula CnH2n+2.
Consider the following equilibrium reaction that has achieved a state of dynamic equilibrium. In a 3.00 L container, the following amounts were determined at 400ºC: 0.0420 mole N2, 0.516 mole H2 and 0.0357 mole NH3. Determine the value of Kc
For 2,5-dimethylhexane, draw a Newman projection (looking down the C3-C4 bond) representing the most stable conformation, least conformation and a gauche conformer
Which of the following molecules have dipole moments? For the molecules that are polar, indicate the polarity of each bond and the direction of the net dipole moment of the molecule.
A sample of silver chromate (Ag2CrO4) has a mass of 24.7 g. (a) How many Ag+ ions are present? ions (b) How many CrO42- ions are present? ions (c) What is the mass in grams of one formula unit of silver chromate? g/formula unit
At equilibrium a 2L vessel contains .410 mol of H2, .130mol of Br2, and 36.0 mol of HBr. What is the equilibrium constant for the reaction at this temperature?
The Substrate, 1-chlorobutane, was not totally consumed in the reaction. As a result, a GC peak for that species appears in the chromatogram.
A gas cylinder with a movable piston initially contains .25 moles of neon in a 5 L. If .5 moles of helium are added to this gas cylinder, what will be the final volume
at conditions of 785.0 torr of pressure and 15.0 Celsius temperature, a gas occupies a volume of 45.5 Celsius what will be the volume of the same gas at 745.0 torr and 30.0 Celsius.
Calculate the molarity of an NaOh solution if 32.6 ml of this solution is required to neutralize 0.854g of potassium hydrogen phathalate. the molecular weight of potassium hydrogen phathalate is 204.277g/mol
A 0.300 g sample of an aspirin tablet is used to prepare 100.0 mL of a stock solution by dissolving the tablet in 1 M NaOH then diluting with distilled water to the 100 mL mark of a volumetric flask. A 0.30 mL sample of the stock solution is then ..
