Question #96121

Answer 1

`F_2 + 2NaCl -> 2NaF + Cl_2` is TRUE. I will let you read the explanation and work out the other cases.

Explanation:

Halogens are more reactive as you go up that column in the periodic table, and the more reactive ones will displace the less reactive ones. Example: Fluorine is above chlorine among the halogens, so `F_2` does react with `NaCl` to give `NaF` and `Cl_2`.
