4Fe + 3O2 = 2Fe2O3 Which of the following is correct?
A. Iron and oxide forms rust which is iron oxide
B. Iron nails rust in oxygen gas to form iron oxide
C. Iron nails rust in oxygen to form iron (III) oxide
D. Iron reacts with oxygen gas to form diiron trioxide

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.

the objects have the same charge.
