Use lewis structures to explain why br3- and i3- are stable, while f3- is not

If you sketch a Lewis dot structure of I3-, you'll perceive that the center I atom formulates two bonds, and also has three non-bonding pairs of electrons. That's an over-all of five electron pairs - beyond an octet. Lots of compounds disrupt the octet rule that means, but the first long-row elements like F can't because the lower elements like iodine can use an obtainable d-orbital to house the additional pair of electrons (sp3d hybridization), but F just doesn't have a d-orbital that it can use.

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.
