Me with the correct answer how many moles of h2o are needed to produce 1 mole of o2 in the following equation? 2h2o > 2h2 + 1o2 a. 3 b. 4 c. 1 d. 2

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: )
