Is SO2 plus O2---SO3 balanced

Answer 1

• S8 + 12O2 = 8SO3.

Since there are 8 sulfur on the left, you must have 8 on the right, so 8SO3. Now you have 24 oxygen on the right, so you need 24 on the left. Multiplying O2 by 12 balances it.

Answer 2

No. To balance this equation you need to do this:

2SO2 + O2 = 2SO3

Answer 3

No, the chemical equation for the reaction of SO2 with O2 to form SO3 is not balanced. The balanced equation is:

2 SO2 + O2 → 2 SO3

Answer 4

It is already balanced as there are three oxygen atoms on both sides.

O+ O2 -->O3

Answer 5

2 so3 --> 2 s + 3 o2
