Draw the lewis structure for each of the following and then determine if the molecule is polar or nonpolar. do not draw double bonds to oxygen atoms unless they are needed for the central atom to obey the octet rule. do not include formal charges in your drawing. no2cl.

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.
