It’s about electron configuration

True

Explanation:

A metal , has 1 electron on the last level, so it can become (A^+1)

C, non-metal,  has 7 electrons on the last level, so it can become (C^-1)

Compound AC is possible

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.
