1.) a.) In the synthesis of ferrocene, why is potassium hydroxide (KOH) added to the cyclopentadiene? b.) Which is more polar, 1,1-diacetyl ferrocene or ferrocene? Which will have the lower Rf value?
Cis-1,2-dimethylcyclohexane and cis-1,4-dimethylcyclohexane have very similar heats of combustion. However, cis-1,2-dimethylcyclohexane is slightly higher. Why?

In reference to: (Polymerization; Nylon-6,6 Organic Chemistry Lab) 1. Why do you add hydroxide to your hexanediamine solution? What would occur if you did not add it?
Chemistry lab question! Help please! A student finds a solution of blue dye #2 (another food dye we are not using in this lab) in a 1.0 cm cuvette has a maximum absorbance of 0.572 at 613 nm. The molar extinction coefficient, E, of blue #2 at the same wavelength is 1.21 * 10^4 M^-1 cm^-1. Calculate the concentration of this solution. The same student as in question 3 brings the blue dye #2 solution to her friend Bob to...
Chemistry word question... In the thermodynamics lab, you determined the temperature at which your saturated Potassium Nitrate solution precipitated out of solution. If during this lab some of your Potassium Nitrate crystalized on your temperature probe and was no longer in solution, what effect would this have on your observed deltaG for the process?
