Which is the balanced equation for s8 + o2 → so2?

s8 + o16 → 8so2
s8 + o2 → s8 + o2
s8 + o2 → s8o2
s8 + 8o2 → 8so2

Answer

S₈ + 8O₂ → 8SO₂

Explanation

S₈ + O₂ → SO₂. There are 8 molecules of S on the left hand side and only 1 on the right hand side. So, to balance this put 8 on the right to balance the S molecules.

S₈ + O₂ → 8SO₂ . Doing this makes the O molecules to be 16 on the right hand side. So, we put 8 as the coefficient of O to the is 16.

S₈ + 8O₈ → 8SO₂
