The chemical equation provided shows iron rusting to form iron oxide. use the drop-down menu to choose the coefficients that will balance the chemical equation. ( )fe + ( )o2 → ( )fe2o3

4Fe + 3O2 → 2Fe2O3 <or> The chemical formula for rust is Fe2O3. Rust is formed when iron reacts with oxygen in moist air. The following chemical equation represents the reaction: 4Fe + 3O2 → 2Fe2O3. Water is necessary for the oxidation reaction to occur and to facilitate transport of the electrons.

The balanced chemical equation is

Explanation:

Rust is reddish-brown coating on iron metal which is formed when iron comes in contact with air and moisture to form ferric oxide. The chemical formula for trust is and chemical name is ferric oxide.

The balanced chemical equation for the formation of rust follows:

By Stoichiometry of the reaction:

4 moles of iron metal reacts with 3 moles of oxygen gas to produce 2 moles of ferric oxide.

Hence, the coefficients are 4, 3 and 2.
