Answer:
The correct answer to the given problem is found to be option (2) B, C and D.
Explanation:
- Rust, or iron oxide, is a fairly common compound and is usually a reddish coating on Iron or steel. It's a naturally occurring phenomenon that happens every day.
- The time when iron is exposed to oxygen and water. Iron and oxygen have opposite charges and are attracted to each other, causing rust. Therefore, they look for every opportunity to connect. Although, rust is considered as an oxidation reaction and not all iron oxides are rusted by default.
- Basically, when the air is dry, the combination of iron and oxygen is not very effective. When there is some water in it, the metal begins to rust. All you need to rust your favorite tools, bikes and cars is oxygen and water,
- Brine rusts much faster than usual. Also, constant temperature changes, various chemicals and minerals, and acids may accelerate corrosion.
