Question

1. steel wool is composed of iron. steel wool reacts with oxygen in the air to form a new compound. identify the formulas of the two reactants in this combination reaction. i need a hint select all that apply: fe fe₂ fe³⁺ this is the correct formula for solid iron. o o²⁻ o₂ submit answer × 2 / 3 submissions used heads up! you need to submit this answer for it to save and be graded.

Explanation:

Step1: Identify solid iron formula

Solid elemental iron is represented as $\text{Fe}$ (already correctly selected).

Step2: Identify oxygen reactant formula

Oxygen in air exists as diatomic molecule $\text{O}_2$, not single $\text{O}$ or ion $\text{O}^{2-}$.

Answer:

Fe, $\text{O}_2$
(To complete the selection, check the box for $\text{O}_2$ along with the already checked $\text{Fe}$)
