Consider the following reaction:
4P +502 P4010
The percent yield of P4010 when 6.20 g of phosphorus burns in
excess oxygen is 67.0 %.What is the actual yield of P4010?
(Molar mass of P = 31.0 g/mol, molar mass of P4010 = 284
g/mol) (Round your answer 3 significant figures e. g. 5.62)
grams

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!
