Answer

Answer:

C. 4, 3, 2

Explanation:

Step1: Balance oxygen atoms

We have 2 oxygen atoms in (O_2) and 3 oxygen atoms in (Al_2O_3). The least - common multiple of 2 and 3 is 6. So, we put a 3 in front of (O_2) and a 2 in front of (Al_2O_3) to balance oxygen: (Al+3O_2\rightarrow2Al_2O_3).

Step2: Balance aluminum atoms

Now, on the right - hand side, we have 4 aluminum atoms in (2Al_2O_3). So, we put a 4 in front of (Al) on the left - hand side: (4Al + 3O_2\rightarrow2Al_2O_3).
