When metallic sodium is dissolved in liquid sodium chloride, electrons are released into the liquid. these dissolved electrons absorb light with a wavelength near 800 nm. suppose we treat the positive ions surrounding an electron very crudely as defining a three-dimensional cubic box of edge l, and we assume that the absorbed light excites the electron from its ground state to the first excited state. calculate the edge length l within this simple model.

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.

consider the reaction below.
