Penny has a pencil that is 19 cm long. how long is this in pounds

No equivalence.

Explanation:

Hello,

Since cm are units of length and pounds are units of mass, there's no relationship between them in therms of length. You could convert those cm to inches or feet which turns out into 7.48 in and 0.623 ft respectively.

Best regards.

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: )
