The following reaction is found to be first order in A: A - B C If half of the starting quantity of A is used up after 56 s, calculate the fraction that will be used up after 6.0 min

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: )
