Question 2 of 34 A team of scientists claim that they have discovered a new experimental
method for determining atomic mass. Which of the following is necessary for
the claim to be considered valid?
A. The atomic mass of an element according to the new method
must be less than its previous measurement.
B. Another team of scientists must be able to replicate the results of
the experiment.
C. The method must work for all isotopes.
D. The atomic mass of an element according to the new method
must be greater than its previous measurement.

Which statement can best be concluded from the ideal gas law?

What does a complete balanced chemical equation include? a. exothermic coefficients b. endothermic coefficients c. valence electrons d. molar coefficients

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.
