A small amount of baking soda is place on a template. Several drops of Vinegar are added to the powder. The resulting reaction leaves none of the powder like substance. It appears to have "disappeared". How can you explain what took
place? Be sure to use the following terms: physical change, chemical change, reaction, reactants, products, evidence of
reaction, evolving of a gas, solution, and compound

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.
