comparison of characteristics
characteristic state x state y state z
average speed of the particles low greatest least
particle attraction/forces weak negligible strong
which of these best describes the state of the substance represented by state z?
it is a solid because strong attractive forces prevent particles from moving.
it is a liquid because strong attractive forces prevent particles from moving.
it is a liquid because weak attractive forces allow for some motion.
it is a gas because weak attractive forces allow for some motion.

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
