Please answer parts a, b, and c An experiment is performed to compare the solubility of L,(s) in different solvents, water and hexane (C,H,). A student adds 2 mL of H,0 and 2 mL ofCH, to a test tube. Because H,O and C,H, are immiscible, two layers are observed in the test tube. The student drops a small, purple crystal of I,(g) intothe test tube, which is then corked and inverted several tìmes. The C,H, layer becomes light purple, while the H,0 layer remains virtually colorless.c. Explain why the hexane layer is light purple while the water layer is virtually colorless. Your explation should reference the relative strengths ofinteractions between molecules of I, and solvents H,O and C,H, and the reasons for the differences.d. The student then adds a small crystal of KI(s) to the test tube. The test tube is corked and inverted several times. Ther ion reacts with I, to form the 1,ion, a linear species.i.In the box below, draw the complete Lewis electron-dot diagram for the I, ion.t ProcessAH" (kJ/mol)Br,() - Br,(g)30.91L(s) – LG)62.44At 298 K and 1 atm, the standard state of Br, is a liquid, whereas the standard state of I, is a solid. Therenthalpy changes for the formation of Br,(g) andL(g) from these elemental forms at 298 K and 1 atm are given in the table above.а.Explain why AH for the formation of 1,(g) from 1,(s) is larger than AH for the formation of Br,(g) from Br,(1). In your explanation identify the typeof particle interactions involved and a reason for the difference in magnitude of those interactions.b.Predict which of the two processes shown in the table has a greater change in entropy. Justify your prediction.5

At 298 K and 1 atm, the standard state of Br, is a liquid, whereas the standard state of I, is a solid. Theenthalpy changes for the formation of Br,(g) and L(g) from these elemental forms at 298 K and 1 atm are given in the table above. a. Explain why AH for the formation of 1,(g) from L(s) is larger than AH" for the formation of Br,(g) from Br,(1). In your explanation identify the type of particle interactions involved and a reason for the difference in magnitude of those interactions. b. Predict which of the two processes shown in the table has a greater change in entropy. Justify your prediction.
