Lennard-Jones potential diagrams, also called intermolecular potential energy diagrams, illustrate the relationship between the potential energy of a molecule as the distance between the two nuclei changes. Select all of the true statements regarding Lennard-Jones potential diagrams. a. As the internuclear distance decreases, the attraction between the nuclei increases significantly, causing a steep increase in the potential energy of the system. b. As the internuclear distance decreases, the nuclear and electrostatic repulsions increase significantly, causing a steep increase in potential energy. c. Once a balance is found between the attractive and repulsive forces, the outer orbitals are able to overlap, thereby allowing a bond to form. d. When the nuclei are infinitely far apart, there is no repulsion or attraction between them; thus, the potential energy approaches zero. e. When the nuclei are infinitely far apart, the attractive forces between the nuclei are much greater than the repulsive forces between them, causing the potential energy to approach zero. f. Once the attractive forces are greater than the repulsive forces, the outer orbitals are able to overlap, thereby allowing a bond to form.

The earth's moon is unusually large. two popular theories of the moon's origin include the "sister world" hypothesis, which states that the moon formed from the same materials as the earth, near enough to the earth that they fell into orbit around each other. a second theory is the "capture" hypothesis, in which the moon formed elsewhere in the solar system, and the earth's gravity pulled it into its orbit. studies of what the moon is made of indicate that some of its materials had to come from the earth or from the same area of the solar system where the earth had formed. at the same time, the moon does not contain much of the material that makes up the earth's core, so the moon could not have formed from the same materials as the earth. how do the two facts above affect the described theories of the moon's origin? a. they show that scientists will never agree on where the moon came from. b. they show that more experiments on moon formation need to be done. c. they show that no theory accounts for the existence of the moon. d. they show that neither theory is complete and entirely correct.
