Based on the Lewis/electron dot representation

of the two atoms, predict the ratio of metal

cationic (+) atom to nonmetal anionic (-) atom in

the compound.

.Ca:

A. 1:1

B. 1:2

C. 2:1

D. 3:1

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.
