Nitrogen and hydrogen react according to the reaction below n2 (g) + 3h2(g) --> 2hh3(g).

if 60 dm^3 of nitrogen and 60dm3 of hydrogen are made to react.
what will be the volume compositions of the individual gases after the reaction in dm3?

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: )

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
