In the reaction represented by the equation n2(g) + 3h2(g) 2nh3(g), the
forward reaction is exothermic. which set of conditions would give the best yield of
ammonia at equilibrium?
a) 800 atmospheres and 2000 oc
b) 1 atmosphere and 500 o
c
c) 1 atmosphere and 2000 o
c
d) 800 atmospheres and 500 o
c

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: )
