(a) calculate the (time-averaged) energy density of an electromagnetic plane wave in a conducting medium. show that the magnetic contribution always dominates. (b) show that the intensity is (k/2μω)e20e−2κz.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
