Cl2 (g) + 2kBr (s) - --> 2KCl (s) + Br2 (g) Rewrite the equation and write the color of each chemical under its name. 2. What type of the reaction is that?

Cl2 (g) (green/yellow mix) + 2KBr (s) (white) - --> 2KCl (s) (violet) + Br2 (g) (reddish brown)

This chemical reaction is a redox type.

Explanation:

Look at the oxidation state, when the number increase your element gets oxidated, when the number decrease, the elements it's getting reduced.
