The dissolution of NH4ClO4 in water is endothermic, with change of H=+33.5kJ/mol. If you prepare a 1.00m solution of NH4ClO4 beginning with water at 26.5 C, what is the final temperature of the solution? Assume that the specific heats of both pure H2O and the solution are the same, 4.18J/(k*g).
use the appropriate relationships from the chapter of electrons in Atoms to determine the wavelength of the line in the emission spectrum of He+ produced by an electron transition from n=5 to n=2
