Given the balanced equation representing a reaction:
4al(s) + 3o2(g) ==> al2o3(s)
as the aluminum loses 12 moles of electrons, the oxygen
(1) gains 4 moles of electrons
(2) gains 12 moles of electrons
(3) loses 4 moles of electrons
(4) loses .12 moles of electrons

Base on the question, which of the following that sates the balance of the reaction and as the aluminum loses 12 moles of electrons, what could be the oxygen, and base on my research, the possible answer among them is in number (2) gains 12 moles of electrons, I hope you are satisfied with my answer and feel free to ask for more 

The molecules contain like 54 of water 

Which of the following did you identify correctly
