At 9: 00 am, a dog chased a squirrel 8 miles north. the dog gave up and stopped chasing the squirrel at 10: 00 am. what was the average velocity of the dog while he was chasing the squirrel?

8 mph south

16 mph north

explanation: no but i do not usually comment

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!

if you need further assistance, let me know: )
