You are sitting inside at 68°F with two cups of liquid water each at different temperature. explain to an acquaintance why a cup of plain water that is 97 degrees Celsius will cool down at the same rate as a cup of plain water that is 75 degrees Celsius. will they reach dynamic equilibrium at 68° f at the same time? assume the mass and volume of both cups of water are identical.

c) always accurate

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: )
