6. Describe how the molecular level structure contributes to the strength of covalently bonded polymers.
A. The polarization of bonds allows the materials to bond even with neutral materials.
B. The transfer of electrons between the atoms allows for strong connections and conductivity.
C. The covalent network of overlapping orbitals and conjugation allows the atoms to bond
strongly.
D. The metallic bonding in the conductive polymers allows electrons freely strengthening the
bonds.

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.
