Please help! What is the identity of the element that produced the unknown emission spectrum and what information does the spectrum give about the source

of the element?

where's the diagram?

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.

i think its 5049.

i hope this !
