I was getting restless to post these questions, so I decided to go ahead and post them.

Balance each of the following skeleton equations.

B) Na + F2 -> NaF

I balanced out this equation like this.

Na + F2 -> Na2F OR would I write it as

-> Na + F2 -> NaF2 , would the 2 go before the F, or after the F?

**Neither. Rule #1 when balancing equations; thou shalt not change the subscripts. Thou may change the coefficients ONLY.

2Na + F2 ==> 2NaF
