Why is the arrangement of the constituent atoms or molecules more important in determining the properties of a solid than a liquid or
a gas? Why are the structures of solids usually described in terms of the positions
of the constituent atoms rather than their motion?

Describe in detail the melting point behavior of the 80: 20 benzoic acid-mandelic acid mixture

This graph gives information on changes in sea ice extent in the arctic ocean over a 30-year span. the overall trend shows in the ice extent. to address the trend, scientists need to ask themselves, one direct consequence of the trend is that

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.
