Write a general equation for the reaction of a halogen with a metal. (Assume the oxidation state of metal equal 3) Express your answer as a chemical equation. Do not identify the phases in your answer. Denote the metal as MM and the halogen as XX.

General chemical equation

          2 M + 3 X₂ → 2 MX₃

Explanation:

When metal reacts with halogens metal halide as a product obtained.

Now oxidation state of metal assume (+3)

and oxidation state  for halogen = (+1)

So formula of the metal halide is (MX₃)

           Denote the metal as M and halogen as X

                    the balanced chemical equation

                         2 M + 3 X₂ → 2 MX₃

So the resulted general equation when metal react with halogen is

                                       2 M + 3 X₂ → 2 MX₃

these nuts

the answer is 303.15 or 303
