What coefficient will Oy have after balancing this equation? C4H2 + O2 → CO2 + H20
O A. 2.5
O B. 4
O C. 8
O D. 6

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: )
