Question

What is the balanced equation for `S_8+O_2->SO_2`?

Answer 1

`S_8(s) + 8O_2(g) rarr 8SO_2(g)`

Explanation:

Alternatively I could use a non-integral stoichiometric coefficient for sulfur:

`1/8S_8(s) + O_2(g) rarr SO_2(g)`, or more simply,

`S(s) + O_2(g) rarr SO_2(g)`

This form might make the arithmetic a bit easier. What is the oxidation state of `S` in `SO_2`?
