The picture shows the average dissolved oxygen values of ocean surface waters. Describe the general trend of the sea surface oxygen as you move from the
equator toward the poles. Explain how this trend relates to the relationship
between the solubility of a gas in water and temperature.

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.
