2.) 2,2,1
3.) 2,1,2
4.) 1,1,1
Please explain how you did this so I can do the others.

did anyone actually do this? like if anyone has submitted this i rly need .

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.

explanation:
