It has been calculated that the observed colored lines in a hydrogen line spectrum correspond to the relaxation of the electron from higher energy level down to the second energy level. Based on this information and how the wavelengths are ranked by energy, match each spectrum line wavelength to its corresponding transition.

A100 kmol/h stream that is 97 mole% carbon tetrachloride (ccl4) and 3% carbon disulfide (cs2) is to be recovered from the bottom of a distillation column. the feed to the column is 16 mole% cs2 and 84% ccl4, and 2% of the ccl4 entering the column is contained in the overhead stream leaving the top of the column. calculate the mass and mole fractions of ccl4 in the overhead stream, and determine the molar flow rates of ccl4 and cs2 in the overhead and feed streams. 12. mw_ccla- 153.82; mw_cs2-76.14.
