How does the law of conservation of mass apply to this reaction: c2h. + 02 + h2o + co2?
only the oxygen needs to be balanced. there are equal numbers of hydrogen and
carbon
each element needs to be balanced.
the equation needs to be balanced. there are fewer oxygen atoms in the equation than
hydrogen or carbon
the law of conservation of mass has already been applied. there is an equal number of
each element on both sides of the equation.

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.
