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

Suppose a pair of chemical compounds a and b can react in two different ways: a + b -> c reaction 1 gives product c. a + b -> d reaction 2 gives product d. the following facts are known about the two reactions: . reaction 1 is endothermic and reaction 2 is exothermic. if a reaction vessel is charged (filled) with a and b , then at first d is produced faster than c. use these facts to sketch a qualitative reaction energy diagram for both reactions. note: because these sketches are only qualitative, the energies don? t have to be exact. they only have to have the right relationship to each other. for example, if one energy is less than another, that fact should be clear in your sketch.
