Avinegar solution of unknown concentration was prepared by diluting 10.00ml of vinegar to a total volume of 50.00ml with deionized water.
a 25.00 ml sample of a diluted vinegar solution required 20.78 ml of 0.1032 m naoh to reach the titration equivalence point.

calculate the concentration of acetic acid (ch3cooh) in the original vinegar solution (before dilution).a. 4.289 x 10^-4 mb. 2.144 x 10^-3mc. 8.578 x 10^-1md. 4.289 x 10^01m

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.

3) in peaches, [oh]=3.16x10-11 m a) find [h+ ] b) what is the ph? c) is the solution acidic, basic, or neutral?

According to the kinetic-molecular theory, what happens to a liquid when it is transferred from one container to another? the volume and the shape stay the same. the volume increases to fill the new container, but the shape stays the same. the volume stays the same, but the shape changes to fit the new container. the volume and the shape change to fill the new container.
