The fluoride rinse in dental offices usually contains sodium fluoride. Sodium fluoride can be prepared from the reaction between sodium metal and fluorine gas. Which properly represents the balanced chemical equation for this reaction? Na(s) + F2(g) → NaF2(s) Na(s) + F(g) → NaF(s) 7Na(s) + F(g) → Na7F(s) 2Na(s) + F2(g) → 2Na2F(s) 2Na(s) + F2(g) → 2NaF(s) Why is it important to understand this equation? What do you think could happen if this is incorrect?
