A shelf containing several chemicals (Salicylic acid, 4-(4-Hydroxyphenyl)butan-2-one {a.k.a. Raspberry Ketone} and 4-methylaniline) fell and the vials shattered. The white powders are hopelessly mixed in a dustpan. You are promised a big fat raise if you can construct a flowchart that a less qualified chemist will follow to separate the three compounds. You must label what extraction steps are to be taken at each point of the separation and how to isolate each compound again as a solid. To ensure that you get the raise, you will also need to suggest a simple chemical test (not spectral) to test the functional groups present in each compound.
Calculate the ph when 47.0 mL of 0.309 M of a certain monoprotic weak acid, HA, is mixted with 47.0 mL of 0.309 M of sodium hydroxide solution
which is commonly known as table sugar, reacts in dilute acid solutions to form two simpler sugars, glucose and fructose, both of which have the formula C6H12O6 At 23C
Calculate the de Broglie wavelength of a neutron moving at 1.17% of the speed of light. _____m
How many grams of formic acid, HCOOH, must be added to 0.210 L of 0.160 M sodium formate, HCOONa, to yield a buffer solution with a pH of 4.10? Assume no volume change. Ka of HCOOH = 5.0 10-4.
Calculate the final concentration of a sodium hydroxide solution prepared by adding 10.00mL of 5.325M sodium hydroxide stock solution into a 250.00mL volumetric flask and then filling to the mark with de-ionized water.
Calculate the change in internal energy of the following system: a balloon is cooled by removing 0.654 kJ of heat. It shrinks on cooling, and the atmosphere does 385 J of work on the balloon.
the equilibrium constant for a chemical transformation can be predicted from its stoichiometric coefficients whereas the rate law must be determined experimentally.
A solution is made up using equal volumes of 2.0 M acetic acid (Ka= 1.8 x 10 to the power of negative 5) and 0.00050 M HCl.
Here is it, Bromine is less electronegative than chlorine, yet methyl bromide and methyl chloride have very similar dipole moments. Why
How much heat is absorbed in the formation of 1.69 mol of NO? Answer units KJ
What is the freezing point of a solution of 1.17 g of 1-naphthol, C10H8O, dissolved in 2.00 mL of benzene at 20°C? The density of benzene at 20°C is 0.876 g/mL. Kf for benzene is 5.12°C/m, and benzene's normal freezing point is 5.53°C.
If 22.8 mL of NO2 gas is completely converted to N2O4 gas under the same conditions, what volume will the N2O4 occupy?
