The reason for the importance of the observation of more weight of calx than metal is to be determined. Also, the phlogistonists’ response to this observation is to be determined. Concept introduction: According to phlogiston theory, every combustible substance contains an undetectable material called phlogiston that is released when it is burnt. The quantity of phlogiston in all combustible substances is variable. The substances like charcoal have a high quantity of phlogiston in them and therefore it is highly combustible. The substances like metals that contain less amount of phlogiston in them are slightly combustible.

Show that a molecule with configuration π4 has a cylindrically symmetric electron distribution. Hint: Let the π orbitals be equal to xf and yf, where f is a function that depends only on the distance from the internuclear axis.

(a) Verify that the lattice energies of the alkali metal iodides are inversely proportional to the distances between the ions in MI (M = alkali metal) by plotting the lattice energies given below against the internuclear distances dMI. Is the correlation good? Would a better fit be obtained by plotting the lattice energies as a function of (1 — d*/d)/d, as theoretically suggested, with d* = 34.5 pm? You must use a standard graphing program to plot the graph. It generates an equation for the line and calculates a correlation coefficient. (b) From the graph obtained in (a), estimate the lattice energy of silver iodide. (c) Compare the results of (b) with the experimental value of 886 kJ/mol. If they do not agree, explain the deviation.
