Answer:
Step-by-step explanation:
Rust is quite simply hydrated Iron oxide because it is as a result of iron allows coming into contact with oxygen(air) and water.
The resulting reaction gives off rust as a product. The chemical reaction is:
4Fe + 3O₂ + 6H₂O → 4Fe(OH)₃.
You can see from above how rust is formed from Iron alloys, Oxygen and water.
As iron is a widely used components in the production of many things such as cars, rust presents a problem because in dissolving away iron, the object produced is compromised and this can lead to serious consequences if left unchecked.
