1. Shown below, a student spotted the three-component mixture onto a TLC plate and developed it using the solvent system listed. Using the Molecular View of the TLC plate provided: a) draw each molecule analyte (3 in total) in the correct position on the TLC plate, b) draw two (2) DCM molecules and one (1) MeOH molecules interacting with either the plate or the analytes, and c) for all molecules, clearly show the relevant intermolecular forces that explain the TLC results.

Earth, a CHEM 40.1 student, extracted a mixture of pigments from the roots of Rubiatinctorum, commonly known as rose madder. Earth spotted the root extract on twohydrophobic silica gel plates. He then placed each plate in separate developing chambers,one containing solvent system WHITE and the other housing solvent system MIX. Earthallowed the chromatograms to develop for around five minutes. Afterwards, he removedthe plates from the containers and placed them inside an iodine chamber. Thechromatograms resulting from the TLC experiment after visualization are illustrated asfollows. The distances travelled by each spot and by the solvents were measured andrecorded in the displayed table.
10g coffee 4g sodium carbonate 40m dichloromethane 160ml distilled water coffee filter What are the principles behind caffeine being extracted from coffee using the above items? 1st sodium carbonate mixed with coffee then brought to a boil for 20min then solution/grinds are filtered. Then solution is added to a separatory funnel with 15ml of dichloromethane and two layers are observed so the bottom layer with DCM contains the caffeine, then this layer is collected in a beaker and dried out using molecular seeds. Then the solvent is brought to a boil with crude caffeine remaining and recystallized using 95% ethanol and brought to a boil again. Then the contents are vaccum filtered and allowed to dry resulting in 30mg caffeine.

Internal standard. When 1.06 mmol of 1-pentanol and 1.53 mmol of 1- exanol were separated by gas chromatography, they gave relative peak areas of 922 and 1 570 units, respectively. When 0.57 mmol of pentanol was added to anunknown containing hexanol, the relative chromatographic peak areas were 843:816 (pentanol:hexanol). How much hexanol did the unknown contain?
A scientist wishes to measure the concentration of methyl benzoate in a plant stream by gas chromatography. He prepares a sample of butyl benzoate to use as an internal standard. The results of a preliminary run, which used a solution known to contain 1.37 mg/mL of methyl benzoate (peak A) and 1.51 mg/mL of butyl benzoate (peak B), are shown. The area of peak A is determined to be 3.40×102 and the area of peak B is determined to be 398 measured in arbitrary units by the computer. To measure the sample, 1.00 mL of a standard sample of butyl benzoate containing 2.49 mg/mL is mixed with 1.00 mL of the plant stream material. Analysis of the mixture gave a peak area of 437 for peak A and 415 for peak B. What is the concentration of methyl benzoate in the plant stream?
Oral rehydration salts are stated to contain the following components: Sodium Chloride 3.5g Potassium Chloride 1.5g Sodium Citrate 2.9g Anhydrous Glucose 20.0g 8.342 g of oral rehydration salts are dissolved in 500 ml of water. 5 ml of the solution is diluted to 100 ml and then 5 ml is taken from the diluted sample and is diluted to 100 ml. The sodium content of the sample is then determined by flame photometry. The sodium salts used to prepare the mixture were: Trisodium citrate hydrate (C6H5Na3O7, 2H2O) MW 294.1 and sodium chloride (NaCl) NW 58.5. Atomic weight of Na = 23. The content of Na in the diluted sample was determined to be 0.3210 mg/100 ml. Determine the % of stated content of Na in the sample. The stated should be 104.5, how??
