Calculate the change in specific enthalpy for co2 going from 500 to 1500 k by using the equation in table a.6.

∆h = cp(∆T) = 1.234 kJ/kgK(1500 – 500)K = 1234 kJ/kg

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: )
