Which of the following statements about equilibrium is true? 1) Equilibrium favors the products when the energy of the products is higher than the energy of the reactants.
2) Equilibrium favors the reactants when the energy of the product is lower than the energy of the reactants.
3) Equilibrium favors the products when they are less stable than the starting material of a reaction
4) Equilibrium favors the products when they are more stable than the starting material of a reaction.

supongo que te refieres al paralaje estelar (observable).

si es así, entonces se puede inferir que la estrella está a más de 200 parsecs.

i'm pretty sure its b i might be wrong though!

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: )
