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?
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?

Need help with this portion
For balancing equations my approach is trial by error.
We want to sum up the atoms on each side and change the coefficients (number in front of each chemical species) until they are equal.
I find the easiest way is to play with the numbers until they add up, and with practice you will see some patterns emerge. There is also this method below recommend by the book.
However you choose to approach it is up to you, everyone has their own methods.
