1. What is the gravimetric factor of SO3 in BaSO4? NOTE: Present complete solution and also the corresponding units.

Solute S has a distribution constant of 5.1 between water (phase 1) and hexane (phase 2). A 71.0 mL solution of S in water is extracted three times with 12.0 mL of hexane. Calculate the fraction of S remaining in the aqueous phase. fraction remaining:

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

What is a colligative property

ST5H.1- Suppose the mean ionic activity coefficient for the ions M2* and X- of the ionic compound M1X2 is Y+ = 0.791. If we could somehow magically know that y+ = 0.888 then what is y_? Type your answer..

Can you please answer number 7 and show all of the steps to the solution

Show that (demonstrate) for an ideal binary solution, where 1 is the solvent and 2 is the solute, the increase in the boiling point of the solvent (ΔT) due to the presence of the solute is given by the relation: ∆T=Kebb2=(T'eb-Teb) where Keb=[R(Teb)2M1]/1000∆vapH1] Keb=ebulloscopic constant Please show all of the steps and calculations used to demonstrate the question. As well as a brief explanation of the principle used.

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…
