When light of frequency 1.30x 1015 s-1 shines on the surface of cesium metal, electrons are ejected with a maximum kinetic energy of 5.2x 10-19 J. Calculate the wavelength of this light in nm.
What are the advantages of working with microscale equipment as opposed to larger equipment in a Williamson ether synthesis of phenacetin experiment.
Pure colored substances mostly exhibit a single peak (i.e. max) in the visible; therefore the simple rules of complementary colors apply. Mixtures are a little more complicated.
An enantiomerically pure acid is treated with racemic mixture of an alcohol having one chiral carbon.
