question Completion Status: QUESTION 4 Which statement A-D about ionic solids is not correct? a. The enthalpy of hidration includes two terms. one for ion-dipole interactions and one for dipole-dipole interactions. b. The melting point of an ionic solid increases as the lattice energy increases. c. The enthalpy of solution consists of two terms: the lattice energy and the enthalpy of hydration. d. The lattice energy depends directly on the product of ionic charges, inversely on...

Question 1 and 2 of the worksheet?
Shang 22 In this figure, P2 is lower energy than P1. By the Hammond postulate, TS2 is also lower energy as well as structurally more like the reactants. Thus the activation energy. EA[2) is also lower Trends in Nucleophile Strength For this discussion, we have to assume the rate factors above apply in reverse that a faster reaction rate is associated with a more exothermic reaction. For nucleophiles, the neutral nucleophiles (amines, alcohols,...

The common laboratory solvent water is often used to purify substances dissolved in it. The vapor pressure of water is 23.76 mm Hg at 25 °C. In a laboratory experiment, students synthesized a new compound and found that when 79.28 grams of the compound were dissolved in 211.4 grams of water, the vapor pressure of the solution was 23.30 mm Hg. The compound was also found to be nonvolatile and a non-electrolyte. What...
