The bonds of the products store 22 KJ more energy than the bonds of the reactants how is energy conserved during this reaction A. The reaction creates 22 KJ of energy when bonds form
B. The reaction system absorbs 22 KJ of energy from the surroundings
C. The reaction uses up 22 KJ of energy when bonds break
D. The surroundings absorbs 22 KJ of energy from the reaction system

the formula would be mgso4

mgso[subscript]4

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.

there are two significant figures.
