If it is already balanced because the compounds aluminum(Al) and oxygen(O) have the same number of atoms
Answer:
unbalanced
Explanation:
Oops I'm sorry, a year late haha. Anyway this is definitely unbalanced.
So if you write this out, you could write it as 4 A, 1 I, + 3O (x2) ---> 2 A, 1 I, 2O (x3).
so 4AI+6O---> 2AI6O
On the left there is 4AI whereas the right has 2AI. They aren't equal nor balanced.
I'm not completely sure but I hope this helps :)
(oh and tell me if I'm wrong I can change my answer)
