Question

What volume of oxygen is needed to react with solid sulfur to form 6.20 L of sulfur dioxide?

Answer 1

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

Explanation:

Given that the reaction proceeds quantitatively, whatever the conditions of temperature and pressure, if there were `6.20*L` of `SO_2(g)`, there were `6.20*L` `"dioxygen"` required to make it. Stoichiometry demands this.

How much oxygen is required to form `6.20*L` of `SO_3(g)` from elemental sulfur?
