6. Compute the heat involved when 42.8 grams of calcium carbide, CaC2, cools from 74.2 C to 11.5 C. The Cp of calcium carbide is 1.00 J/g • °C.
(Number 6)))

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: )
