We won't do homework for you.

Take some guesses. What do you know?

Here... a "gimmie"... I don't like giving people answers, but this is a simple one...

NaCl-->Na+Cl2

Notice there are two chlorines on the right and not the left... OK you need two on the left

2NaCl-->Na+Cl2

So that balances the Cl, but now the Na is off... 2 on the left, one on the right... so...

2NaCl-->2Na+Cl2

There's a start
