The predicted yield for a reaction was 10g of product. If the percentage yield for this reaction was 50%, how much product was 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!

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2

answer carbon and three oxygen atoms;
