Acalled a reductant or reducer) is an element or compound that loses (or "donates") an electron to an electron recipient (oxidizing agent) in a redox chemical reaction.

a reducing agent is thus oxidized when it loses electrons in the redox reaction. reducing agents "reduce" (or, are "oxidized" by) oxidizing agents. oxidizers "oxidize" (that is, are reduced by) reducers.

A reducing agent is an element or compound that loses (or "donates") an electron to an electron recipient (oxidizing agent) in a redox chemical reaction.

Explanation:

Redox reaction is defined as the reaction in which oxidation and reduction reaction occur simultaneously.

Oxidation reaction is defined as the chemical reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

Electrons are transferred from one atom to another in this type of reaction.

Reducing agent is defined as those substance which reduces other chemical compound and oxidizes itself by donating electrons.

Oxidizing agent is defined as those substance which oxidizes other chemical compound and reduces itself by accepting electrons.

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.
