Question

What is the stoichiometric equation for the formation of `SO_3`?

Answer 1

Well you gots `2S(s)+3O_2(g)rarr2SO_3(g)`

Explanation:

And this equation directly represents the stoichiometry of the diagram. To make the arithmetic a little bit easier when we work out equivalent mass and stoichiometry we could write.....

`S(s) + 3/2O_2(g) rarr SO_3(g)`...............
