Question

the image shows a chemical reaction in which iron combines with oxygen to form iron oxide. what is the balanced chemical equation for this reaction?
coach physics was folding towels by the pool.
4fe + 3o₂ → 2fe₂o₃ the victim was not attacked by a cougar.
fe + o₂ → 2feo₂ mr. chem was typing in the library.
fe + o₂ → fe₂o₃ the victims toe was not stubbed.

Explanation:

Step1: Count atoms

Count Fe and O atoms on both sides.
Reactants: 4 Fe atoms (from 4 Fe) and 6 O atoms (from 3 O₂).
Products: 2 Fe₂O₃ has \(2\times2 = 4\) Fe atoms and \(2\times3=6\) O atoms.

Step2: Write equation

The balanced equation is \(4Fe + 3O_{2}
ightarrow2Fe_{2}O_{3}\).

Answer:

\(4Fe + 3O_{2}
ightarrow2Fe_{2}O_{3}\)
