2. Consider the carbon atom (ground state configuration 1s22s22p2) and oxygen atom (groundstate configuration 1s22s22p4).(a) Write out the electron configuration (microstate) corresponding to the lowest energyconfiguration of carbon and oxygen. What areLandSin each case?(b) What values ofJare possible with the values ofLandSthat you found for carbon andoxygen in part (a)? Use Hund’s third rule to determine the complete term symbols forthe ground states of carbon and oxygen.

When an object falls through the air and encounters air resistance its overall speed will be than if it had not encountered air resistance? (one word answer)

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.
