Which contribution added to rutherford's discovery of a positive nucleus? atoms are indivisible. electrons are scattered in an atom. neutrons are inside the nucleus of an atom. atoms of the same element have the same properties.

i think it's c. i'm not sure but i think so.

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.
