ANSWER ASAP GIVING BRAINLIEST FIVE STARS AND HEART! How do mechanical waves transport energy?

A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. ... Once this initial energy is added, the wave travels through the medium until all its energy is transferred. In contrast, electromagnetic waves require no medium, but can still travel through one.

Explanation:

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
