Answer:
[tex]2Na+Br_2[/tex] → [tex]2NaBr[/tex]
Explanation:
[tex]Na+Br_2[/tex] → [tex]NaBr[/tex]
On the left you have:
Na: 1
Br: 2
On the right you have:
Na: 1
Br: 1
To get the Br to be the same on both sides, you would multiple the NaBr by 2. Then, you will have 2 Na so you put a coefficient of 2 in front of the Na aswell.
