Answer:

  • The left side contains the reactants whose names are: iron (Fe) and oxygen (O₂).

Explanation:

The left side of the equation contains the reactants and the right side contains the products.

The chemical equation is:

  • 4 Fe + 3O₂ → 2Fe₂O₃

Fe is the chemical symbol of iron. So, this part is iron.

O is the chemical symbol of oxygen. Since oxygen gas is a diatomic molecule the superscript 2 is used: O₂.

You can write the word equation to show the name of every partl on each side:

  • reactants           →      products
  • iron + oxygen    →     iron(III) oxide.
