4. Calculate the (molar) energy of electrostatic repulsion between two hydrogen nuclei at the separation in H, (74.1 pm). The result is the energy that must be overcome by the attraction from the electrons that form the bond. Does the gravitational attraction between them play any significant role? Hint: The gravitational potential energy of two masses is equal to –Gm;m,/r; G is listed inside the front cover.

Principal Quantities and EOS

A physical quantity represents the physical state of a system. It is expressed as the product of a number and unit. The basic quantities used in science are length, mass, and time. The principal quantities are the quantities that are independent of other quantities.
