In this problem you will estimate the polarizability of a carbon atom. imagine you rub a plastic pen through your hair, depositing 1.4 × 10−8 c on the tip of the pen. you move the tip of the pen toward a small scrap of paper, and the paper just begins to lift when the tip is 0.01 m away. assume that the outermost electron cloud of carbon (containing 4 electrons) shifts a distance s when polarized by the pen. first find this charge separation s, then use it to solve for the polarizability of carbon. the mass of one carbon atom is 2 × 10−26 kg. [the measured value of αc is 1.96×10−40. expect to calculate an answer within about a factor of 10 of this value.] assume the acceleration due to gravity is 9.8 m/s 2 .

Suppose you got a low yield of benzoin from your benzoin condensation reaction and thus only have 0.300 g of benzoin to use as the starting material for this reaction. how much concentrated nitric acid should you add? (concentrated nitric acid is 15.8 m). write your answer in the form x.xx ml
