The picture is 1.)A 1B.) If DHsolution for dissolving DMSO in methanol is negative, what does this say about the energy released in mixing methanol and DMSO molecules (DHmixing) as compared to the energy required in separating solute molecules from each other (DHsolute) and separating solvent molecules from each other (DHsolvent)? What can you conclude from this about the strength of DMSO-methanol interactions? Which “wins” in this case? Enthalpy? Entropy? Both? Explain
3. A sealed glass vial is prepared with 4 mL of air and 36 mL of water. Trichloroethylene (TCE) is added to the water to create an initial aqueous phase concentration of 100 ppb (a) (b) After the system equilibrates, what will the concentration of TCE be in the aqueous phase (in µg/L)? Determine the % mass partitioning of TCE between the water and the air when equilibrium is established. (c) If a quantity of TCE is accidentally spilled into a well-mixed river, where would you expect most of the TCE to end up in the short term - in the air or in the water? Explain.
The complete ionic composition of natural waters often is not known, aquatic chemists have developed equations to estimate ionic strength (/) from readily available information such as electrical conductivity (e.g., specific conductance (SC) in µS/cm) or total dissolved solids (TDS): /= 1.6 × 10-5 × SC (for 1 <0.06); / = 1.3 × 10-5 × SC (for 1 < 0.5) /= 2.5 x 10-5 × TDS; TDS ≈ b × SC (b= 0.55-0.70) Your field measurement of a stream sample gave a specific conductance of 100 µS/cm, and your analysis of the water gave concentrations of Na+, Ca²+, Cl-, and HCO3 of 9, 21, 6, and 45 mg/L, respectively. Are these measurements consistent?
In a reverse-phase separation, a solute was found to have a retention time of 19.6 min, while an unretained peak had a retention time of 1.45 min when the mobile phase was 20/80 v/v% methanol/water. (b) Calculate the k’ for the solute. (c) Calculate the new k’ if the mobile phase is changed to 60/40 methanol/water assuming identical void volume. (d) Calculate a solvent composition that would bring k’ from initial value to a value of 1.20 using tetrahydrofuran/water mobile phase rather than 20/80 v/v % methanol/water.
Solution Calculations Using unit analysis, clearly show the set-ups for your calculations. You wish to prepare 50.0 mL of 2.30 x 10–2 M solution of (Levothyroxine) C15H11I4NO4 drug. (hint-how many grams will you need of this drug?) Describe how to prepare this solution from the pure drug and deionized water. Analytical balances and volumetric flasks are available to you. (Assume that this drug dissolves in water, at least to the extent necessary for this problem.) Use complete sentences in your description of the solution preparation process. Thank you!!

Penicillin F is recovered from a dilute aqueous fermentation broth by extraction with amyl acetate, using 6.5 volumes of solvent per 100. volumes of the aqueous phase. At pH = 3.8 the distribution coefficient KD is 74. (a) What fraction of the penicillin would be recovered in a single ideal stage?

Florence is only able to find 0.015 M aqueous KI/I2 on the reagent cart, so they perform a dilution by combining 10 mL of water and 10 mL of the available reagent. They now have 0.0075 M aqueous KI/I2 which can be used at station C. Is there a difference in the chemical composition of the solution Florence made from what was available on the reagent cart? Group of answer choices no, because water was already present in the solution yes, because water was added to the solution
