Draw both staggered and eclipsed conformations of ethane as Newman projections and as dash-and-wedge drawings. Second, state the two theories for the attempt to explain the lower potential energy of staggered conformations of ethane compared to eclipsed conformations of ethane and then compare and contrast the two theories succinctly by discussing the stabilizing and/or destabilizing interactions in each conformation under the two theories. You will need to draw valence bond orbitals on top of your dash-and-wedge drawings to properly discuss one of the theories.
when a metal was exposed to light at a frequency of 4.63*10^15 Hz, electrons were emitted with a kinetic energy of 3.10*10^-19 J.
