The amount of energy released from a fission reaction is much greater than the energy released from a chemical reaction because in a fission reaction
(1) mass is converted into energy
(2) energy is converted into mass
(3) ionic bonds are broken
(4) covalent bonds are broken

Mass is converted into energy.

Explanation:  There are mainly 2 types of nuclear reactions -

a) Nuclear Fission - in which one heavy nucleus gets break into two or more products releasing tremendous amount of energy especially kinetic energy. The amount of energy released due to mass-energy equivalence principle is higher as some amount of mass of the nucleus gets converted into the energy thus decreasing the mass.

The image of the reaction is attached.

b) Nuclear Fusion - in which 2 or more nuclei fused together to form a heavy nucleus  .

can you list the answers so i can answer

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.
