The emission spectrum of hydrogen shows discrete, bright, colored lines. which characteristic of the bohr model is best supported by this observation? energy is released when an electron moves to a higher energy level. smaller atoms have fewer spectral lines than larger atoms. the energy of an electron increases with distance from the nucleus. electrons cannot exist in locations other than in specific orbits.

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.
