- 4. The common oxidation number for an alkaline earth metal is +2. (a) Using the Born-Mayer equation (for determining the lattice enthalpy) and a Born-Haber cycle (draw it), show that CaCl is an exothermic compound (negative AHf). Make a reasonable prediction to estimate the ionic radius of Ca (explain your reasoning). The sublimation (atomization) enthalpy for Ca(s) is 178 kJ/mol. (b) Show that an explanation for the non-existence of CaCl can be found in the enthalpy change for the reaction below. The AHf for CaCl2(s) is -190.2 kcal/mol. 2 CaCl(s) → Ca(s) + CaCl2(s)Chemistry In a TLC experiment, three spots were made. In spot A was a crude sample of a mixture of three compounds ethyl 4- aminobenzoate (base), salicylic acid, and naphthalene as the neutral compound. In spot B, was just the neutral compound, naphthalene. In spot C was the pure compounds of spot A. When dipped with KMnO4, it is said that all spots should turn yellow, but while doing the experiment it was only the bottom compounds that turned yellow for me which I found out was the acid. Should all spots really turn yellow?

In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to Thermometer measure the energy of a solution phase reaction. A stúdent heats 63.82 grams of silver to 99.27 °C and then drops it into a cup containing 83.16 grams of water at 24.20 °C. She measures the final temperature to be 27.20 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.57 J/°C.
