Answer to Question #253441 in Inorganic Chemistry for shamsa

Question

Everyone knows that helium makes your voice high pitched, but there is another gas with the opposite effect. It is composed of the elements Sulfur and Fluorine, with the molecular formula SF6. Let’s assume that we perform a reaction in the lab at constant temperature and pressure and that both Sulfur (assume sulfur is monatomic in this state) and Fluorine are in gaseous form. What ratio of elements would give us only product without excess starting material?

Answer 1

Equation of the reaction: S + 3 F ₂ ---> SF ₆

From this equation, we see that we need 1 mol Sulfur and 3 mol F ₂
