Which statement describes a reaction at 298 K if AH = 31 kJ/mol, AS = 0.093 kJ/(mol-K)?
A. It is at equilibrium.
B. It is not spontaneous.
C. It is exothermic.
D. Gibbs free energy is negative.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

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: )
