10. Given the reaction: 4 NH3(g) + 5 O2 (g) ---> 4 NO (8) + 6 H20 (1)
120 mole of ammonia reacts, the total number of moles of products formed is:
When 1.2
a. 1.20 b. 1.50 c. 1.80 d. 3.00 e. 12.0

h let me think

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: )
