Answer:
D
Explanation:
Look at the equation right now. In order to balance it, the number of each element on both sides needs to be the same.
Right now, the left side has:
- 1 C
- 4 H
- 2 O
The right side has:
- 1 C
- 4 H
- 4 O
We see that the number of O on each side is not the same; we need to make the number of O on the left 4. So, just add a 2 to the [tex]O_2[/tex], as that will produce 4 O.
Hope this helps!
