Answer:
2NaF + 1Br2 -> 2NaBr + 1F2
Step-by-step explanation:
2NaF + 1Br2 -> 2NaBr + 1F2
I simply looked at both the left side and right side and saw there was only 1 F on the left side while there were 2 on the right side.
This means we have to make the left side have 2 F by multiplying NaF by 2.
However, this means there are now 2 Na as well. Going back to the right side, I multiplied NaBr by 2 so that there are 2 Na on both sides.
Now there are 2 Br on the right side. Checking back to the left side, there are also 2 Br, meaning this equation is now balanced.
