If the AHsolution, KI = 15 kJ/mol, then calculate the lattice energy for potassium iodide using the data from a standard reference table shown here.
DeltaHhydration
K+ -335kJ/mol
I- -293kJ/mol

Fill in the blanks for the following statements: the rms speed of the molecules in a sample of h2 gas at 300 k will be times larger than the rms speed of o2 molecules at the same temperature, and the ratio µrms (h2) / µrms (o2) with increasing temperature.
