Post Lab Questions: 1. What did you notice about the distance between the atoms as the number of bonds increased? (Compare bond of H2S and H20) 2. What is the relationship between atomic size and bond length for H2O/HS and CO2/ CS2? 3. What are the carbon-carbon bond lengths in each of these three molecules? Using Table 7.2 draw the structures for C2H, CH4 and C2H2, and determine the carbon-carbon bond lengths for each structure. 4. What is the pattern in bond length that you notice for the carbon compounds in question 3?

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.
