Chemical reaction | Definition, Equations, Examples, & Types
Reactants are converted to products, and the process is symbolized by a chemical equation. For example, iron (Fe) and sulfur (S) combine to form iron sulfide (FeS). Fe(s) + S(s) → FeS(s) The plus sign indicates that iron reacts with sulfur. The arrow signifies that the reaction "forms" or "yields" iron sulfide, the product.

9.1 The reaction of iron with oxygen
Rust is a form of iron oxide. When iron is exposed to oxygen in the air, a similar reaction occurs, but much more slowly. The iron is gradually 'eaten away' as it reacts slowly with the oxygen. Under wet conditions iron will rust more quickly. Rust is actually a mixture of different oxides of iron, but the Fe 2 O 3.
