Find P given that 25 mL of toluene and 25 mL of an aqueous solution containing 0.000330 moles of an organic compound were shaken together and 31 % was extracted into the organic phase.
The Wittig reaction involves coupling between a phosphonium ylide and a carbonyl-containing molecule. If a chemist wants to use the Wittig reaction to synthesize 3-methyl-3-hexene, which reactants should be used
For example if your compound is water and you have the information the boiling point, Tb=(99.98 C), the enthalpy of vaporization= (40.65 kJ/mol) and the molar mass= 18.02g/mol.
The pKa of acetic acid, HC2H3O2, is 4.76. A buffer solution was made using an unspecified amount of acetic acid and 0.30 mol of NaC2H3O2 in enough water to make 1.50 L of solution. Its pH was measured as 4.50 on a meter.
The reaction of 2,2-dimethyl-1-propanol with HBr is very slow and gives 2-bromo-2-methyl-propane as the major product. Give a mechanistic
A certain sunstance, intially present at 0.0800 M, decomposes by zero-order kinetic with a rate constant of 2.50 x 10-2 mol/l s. Calculate the time (in seconds) required for the system to reach a concentration of 0.0630
synthesis of methyl orange as a guide, outline an experimental strategy for its synthesis, using any shelf-stable starting materials of your choice. Be sure to also include relevant details such as solvents, reaction temperature, cooling/heating
At the equivalence point all carbonate has been converted to bicarbonate NEt ionic equation before the equivalence point: Net ionic equation at the equivalence point
Using curved arrows to symbolize the flow of electrons, write the stepwise mechanism for the acid-catalyzed esterification of p-aminobenzoic acid to give ethyl p-aminobenzoate.
A conducting sphere of radius 10 cm has an unknown charge. If the electric field 20 cm from the centre of the sphere is 1.5 × 103 N/C and points radially inward
how thick of a veneer is required if some of the water from the meteorite dissociates and the resulting oxygen is used to oxidize one third of Fe+2 in the outer 800 km of the 6000 km proto earth to Fe3+?
if 0.10M aqueous solutions are prepared of each of the following acids, which produces the solution with the lowest pH?
At 100 ?C the vapor pressures of hexane and octane are 1836 and 354 torr, respectively. A certain liquid mixture of these two compounds has a vapor pressure of 666 torr at 100 ?C. Find the mole fractions in the liquid mixture and in the vapor phas..
