Provided a balanced equation with variables (X & Y) instead of actual elements. Determine the charge of the variable X and Y? 4X + 3Y, → 2X Y3
X is +1 and Yis-2
Xis +2 and Yis-2
Xis +3 and Yis-2
X is +2 and Yis-3

i'm assuming that the correct answer is indeed the first one/ "a"..

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.
