Question

1. a new compound forms when energy is applied to the iron (steel wool) and oxygen. observe the reaction in the interactive video. identify the formula of the new compound that forms in the reaction between iron and oxygen. i need a hint fe + o₂ → a submit answer 0 / ∞ submissions used

Explanation:

Step1: Recall oxidation of iron

Iron reacts with oxygen in a redox - reaction.

Step2: Balance the chemical equation

The reaction of iron ($Fe$) with oxygen ($O_2$) to form iron(III) oxide ($Fe_2O_3$) is $4Fe + 3O_2
ightarrow2Fe_2O_3$.

Answer:

$Fe_2O_3$
