If the net force on a hot-air balloon is directed straight upward, which way does the acceleration point?
a. it doesn’t accelerate b. upward and downwind c. downward d. upward

upward (F=ma if f is up a is up)

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: )
