In which of the following reactions is chlorine (cl) oxidized? br2 + 2cl− → cl2 + 2br− cl2 + 2e− → 2cl− 2clo3− + 12h+ → cl2 + 6h2o 2na + cl2 → 2nacl

Explanation:

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

On reactant side:

Oxidation state of chlorine = -1

On product side:

Oxidation state of chlorine = 0

The oxidation state of chlorine increases from -1 to 0. Thus, it is getting oxidized and it undergoes oxidation reaction.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
