17. A dog rolls on the ground with a force of 15 N and accelerates at a rate of 3 m/s2; a second dog rolls on the ground with a force of 25 N and accelerates at a rate of 4 m/s2. What are the masses of the
two dogs?

the answer is learned

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: )
