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.
For weak acid, HX, Ka = 1.0 10^-6. Calculate the pH of a 0.82 M solution of HX.
A zero-order reaction has a constant rate of 3.20×10-4 . If after 60.0 seconds the concentration has dropped to 6.50×10-2 , what was the initial concentration?
A buffer solution is prepared by placing 5.86 grams of sodium nitrite and 32.6 mL of a 4.90 M nitrous acid solution into a 500.0 mL volumetric flask and diluting to the calibration mark
A 5.5 g sample of metal at 100.0 degrees celsius is placed in a calorimeter with 20.0 g of water at 15.0 degree celsius. If the temperature of the water rises to 21.0 degrees celsius, what is the specific heat of the metal?
Draw the molecule by placing atoms on the grid and connecting them with bonds. If there is more than one answer, draw all o
The density of acetic acid vapor at the narmal boiling point, 118.5 degrees C, is given as 3.15 g/L (normal boiling point is the boiling point at P =1 atm). a) calculate the fraction of the vapor that is the monomer and the fraction that is the dim..
A zero-order reaction has a constant rate of 1.90×10-4 . If after 40.0 seconds the concentration has dropped to 6.50×10-2 , what was the initial concentration?
the process (A-> B is first order with a half-life of 0.21 seconds. How long would it take for 15.0M of A to decrease to 0.25 M?
Use the appropriate standard reduction potentials to calculate the value
If a bottle of nail polish remover contains 175mL of acetone, how much heat would be released by its complete combustion? The density of acetone is 0.788g/ML.
Determine the mass of aluminum acetate that can be made if you do the reaction with 125 grams of acetic acid and 275 grams of aluminum hydroxide.
If there was 0.5011g of KClO3 in the original mixture, what is the true percent of KClO3?
