Question

science ok so ok ya its hardf plz anwser me plz i really need it

Answer 1

NO.  It isn't balanced.  To be balanced, you must have the same number of atoms of each element on the left and right. The way you have it written you have 2 Al on left and 1 on right.  So, the correctly balanced equation would be

2Al₂O₃ ==> 4Al + 3O₂
