Can you please help? I'm no good at separation schemes.
Devise a solvent extraction method that could be used
to separate a mixture of powdered sugar, cornstarch, cocaine, and
amphetamine. Be sure to justify each step and
separation.

can you pleas help me making a Flow chart for separation a mixture of trans-cinnamic acid, 4-phenylphenol, and nicotinamide by extraction? thank you Procedure Your mission is to separate a mixture of trans-cinnamic acid, 4-phenylphenol, and nicotinamide by extraction. Start by dissolving/suspending two grams of the mixture in approximately 50 mL of diethyl ether. (Caution: Diethyl ether is extremely flammable! Extract the ether twice with -25 mL of 5% HCl and then twice with -25 mL 5% sodium bicarbonate. It...

Need help on providing reactions that describe the acid-base extraction and neutralization processes used in this experiment. Provide a statement of solubility of each starting material and product. The experiment to be performed this week involves liquid-liquid extraction using a separatory funnel. Read chapter 15 in Zubrick to familiarize yourself with the use of the glassware for extraction and washing. Acid/Base Extraction Liquid-liquid extraction is a technique that can be used to physically separate two substances that have varying solubility...
Hello, can someone please help me with this problem? I'm not very good with Trig, so if you could show the work that'd be great. Thanks! 7. An airplane is flying in the direction E 32° (32), with airspeed of 875 km/h. Because of the wind, the resulting groundspeed and direction are 800 km/h and E 40° S or -40°. Find the direction and speed of the wind. (3 points) 7. An airplane is flying in the direction E 32°...
You will apply what you have learned earlier in the semester when performing the Acid-Base Extraction experiment to perform a different separation: that of an organic neutral compound and organic base. You will also need to purify and characterize these compounds. You will have one lab period to execute your plan for separating the assigned mixture given below. There will be a 1:1 (by mass) mixture placed in the lab: 1,4-dichlorobenzene/ethyl 4-aminobenzoate. You will take approximately 1 g of your...

Can you pleasee answer these questions: If we performed electrophoretic separation (AGE) of human genomic DNA (buccal swab extraction), and we didn’t perform any restriction digestion, answer the following: 1. How many bands do you expect to see in each lane where genomic DNA is loaded? 2. Why do you see bands above the molecular marker? 3. How many wells do you see on the gel? How many of them are used in the experiment (i.e. have loaded samples)? Thank...
