(a) What is the shortest possible wave length of light that can beemitted by such an atom? Assume all transitions are possible. (Donot calculate the wave length of all possible transitions. Reasonout which transition produces the shortest wave length and thencalculate the corresponding wave length.)

what is the freeenergy change for the equilibrium between hydrogen iodide hydrogen and and iodine at 453deg? i
Given that Delta H (fusion) of water is 6025 J/mol, Cp(ice) = 37.7 J/K mol, and Cp(water,liquid) = 75.3 J/K mol, calculate Delta G (in J) for the freezing of 54 moles of water at 1 atm pressure and the constant temperature T =13.1 C.
An ideal solution is formed from a mixture of the nonvolatile solute urea, CO(NH2)2, and methanol, CH3OH. The vapor pressure of pure methanol at 20°C is 89 mmHg. If 4.9 g of urea is mixed with 31.0 g of methanol, calculate the vapor pressure of th..
