They opposed the use of energy released during nuclear fission at the time of war.
They supported the use of radioactive elements for medical diagnostic purposes.
They opposed the use of nuclear fusion during the Manhattan Project.

The answer is “They supported the use of radioactive elements for medical diagnostic purposes”.

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.
