If you begin with 1250 grams of n2 and 225 grams of h2 in the reaction that forms ammonia gas (nh3), how much ammonia will be formed? what is the limiting reagent? how much of the reagent is left when the maximum amount of ammonia is formed?

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: )
