A: 4.91 g of LiCl was dissolved in 50.0 mL of water in the same calorimeter as in problem 1. Analysis of the thermogram showed the initial temperature to be 22.9°C, the final temperature to be 49.2°C. Was the dissolution of the ionic solid exothermic or endothermic? B: Using the information above, calculate the mass of the water. C: Calculate ΔHsolution D : Calculate the standard molar enthalpy of solution. Assume that the pressure is 1 bar.
Consider the melting points of the substances below (see figures for two compounds). Explain the trend in melting point using your knowledge of intermolecular forces. (In the structures below, carbon is black, hydrogen is white, and oxygen is red.) Substance Melting Point (°C) Molar Mass (g/mol) Cl2 −102 71 Ethyl formate (CH3CH2OCHO) −80 74 Propionic acid (CH3CH2COOH) −20 74 Br2 −7.2 160
