A65.0-gram sample of some unknown metal at 100.0° c is added to 177.1 grams of water at 24.5° c. the temperature of the water rises to 27.0° c. if the specific heat capacity of liquid water is 4.18 j/ (°c × g), what is the specific heat of the metal?

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: )
