Indicate the number of h2 and n2 molecules needed to yield two molecules of nh3

This can be fixed by multiplying the product contacting nitrogen by 2. o The new chemical equation is N2 +H2 →2 NH3 Reactants Products Nitrogen 2 2 Hydrogen 2 6. Since NH3 is multiplied by a coefficient of 2 there are now 2 nitrogens and 6 hydrogens.

Explanation:

N/A

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: )
