A certain reaction is endothermic in the forward direction. The reaction has less moles of gas on the product side. Which of the following stresses would increase the yield of the products (shift right)? A) Increasing the pressure
B) Decreasing the temperature
C) Increasing the volume
D) Decreasing the reactant concentration

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: )
