4 In the prior problem set we used the regular solution model to show that oil and water do not mix unless the solution is very dilute. But regular solution theory is not the best model to use for such a calculation because oil and water do not have similar molecular volume. Here we use Flory-Huggins Polymer theory to explore if oil and water mix. Assume oil is a hydrocarbon polymer for which N=10 and water is the solvent. For hydrocarbon-water mixtures assume wSP=5 and T=300K. Assume the volume fraction of oil is φoil=0.3. a. Calculate ΔS¯MIX . b. Calculate \(\Delta \bar{H}_{MIX)\) assuming the same conditions as part A. c. Calculate ΔG¯MIX assuming the same conditions as part A.
synthetic ion exchange resins. These resins are organic polymeric networks that contain functional groups that are permanently attached to the resin. One such functional group is sulfonic acid, -SO3H. When placed in water, the resin (being a large organic molecule) will not dissolve. However, the ionic functional groups become hydrated and the resin will swell as it takes up waters of hydration. The resin may then be thought of as a solid solution mixture with the functional groups being "dissolved" but the polymer remaining as a solid. The hydronium ion (H3O+) associated with acidic functional groups like sulfonic acid will dissociate just as it would if the acid were free of the resin. If other cations such as Cu2+ or Na+ are added to the resin, an ion-exchange reaction can occur: . Note that one H+ is released for each positive charge bound to the resin. Since the resin exchanges a hydrogen ion for a sodium ion in this reaction, sulfonic acid resins are called cation-exchange…
The human microbiome is one of the major frontiers of current scientific investigation. Increasing the diversity within your "gut" can be achieved by consuming probiotics from fermented foods and beverages such as sauerkraut and kefir. Kombucha is a tea co-culture of bacteria and yeast (called a SCOBY) and ethanol is one of the products of this fermentation. Lindsey regularly drank kombucha for its perceived health benefits but was concerned about her blood alcohol level. When drinking kombucha, Lindsey's maximum blood alcohol concentration (BAC) reached 0.9 mg/100mL of blood. Given that the initial half-life for ethanol in the body is 40 minutes, what will be Lindsey's BAC after one hour (60 minutes)?
Rubbing alcohol is often used as a disinfectant and sometimes as a component of handsanitizers. If you were to purchase a bottle of rubbing alcohol at a store, it would most likely sayisopropyl alcohol or isopropyl rubbing alcohol, although it is also called isopropanol. Ethylalcohol is also used in hand sanitizers, and is actually more commonly used. Why would a handsanitizer whose major component is ethyl alcohol evaporate more quickly than one whose majorcomponent is rubbing alcohol?

The molecular mass of a polyethyleneglycol (PEG) can be quite variable; the osmotic pressure of a solution containing 1.358 g of PEG dissolved in a final volume of 420.27 mL was 30.572 torr at 25.00�C? What is the molecular mass of the compound? 199.1 g/mol 322.2 g/mol 1965.3 g/mol 164.8 g/mol
Given that the solubility of any organic material in a given solvent is due to the intermolecular forces present between the solvent and solute, solvents like hexanes (the alkanes isomers of C6H14) are rarely used for extraction purposes. In the space provided here, suggest a reasonable explanation for this experimental observation.
