An electron in the n = 4 level of an H atom emits a photon of wavelength 97 nm. To what energy level does the electron move?
A few of cyclohexane solvent vaporized during the temperature versus time measurement. Will the loss of cyclohexane result in its freezing point being recorded as too high, too low or unaffected. Explain.
A valuable archeological flint arrowhead is to be examined for nickel as a trace component by ED-XRF (x-ray fluorescence). Flint is a silica material similar to quartz. A blank nickel-free quartz sample yields a signal of 7.8 units of intensity.
