The fluoride rinse in dental offices usually contains sodium fluoride. Sodium fluoride can be fitted from the reaction among sodium metal and fluorine gas. Which uprightly represents the balanced chemical equation for this reaction?

  1. Na(s) F2(g) → NaF2(s)
  2. Na(s) F(g) → NaF(s)
  3. 7Na(s) F(g) → Na7F(s)
  4. 2Na(s) F2(g) → 2Na2F(s)
  5. 2Na(s) F2(g) → 2NaF(s)

Why is it main to interpret this equation? What do you judge could betide if this is inaccurate?
