Sulfur and fluorine react in a combination reaction to produce sulfur hexafluoride:
S (s) + 3F2 (g) SF6 (g)
What is the minimun number of moles of fluorine gas needed to completely react with 16 g sulfur?
You didn't type in the arrow? How do we know the difference between the products and the reactants?
a. Convert 16 g S to moles. moles = grams/molar mass.
b. Using the coefficients in the balanced equation, convert moles S to moles fluorine.
Post your work if you get stuck.
