What substances can rust?
Rust is cause by the oxidation of Iron. Basically, when Iron reacts with Oxygen, Rust is fromed. 2Fe2 + 3O2 ---> 2Fe2O3 (Rust) For this reason, it is only things made out of Iron that can rust. I hope I helped! :)
What two substances react to make rust?
The most obvious factors necessary for the corrosion of iron (or the making of rust) is water and oxygen. Iron will not rust if it is kept away from water and oxygen
What happen when iron is exposed to air?
If an iron nail is exposed to air for a long time it reacts with the water vapour (moisture) and oxygen present in the atmosphere and a reddish-brown powdery coating is formed on it known as RUST (Fe2O3.xH2O) .
Is fuel a liquid?
What are two substances that are needed for iron to rust
What two substances that cause metals to rust faster?
Iron in the presence of oxygen and water, or air moisture, will combine to form Iron Oxide or it more common name rust. But Iron can also combine with chlorine in an oxygen free environment such as re-bars (reinforced concrete post) to form a green rust called Fougerite.
Which two substances must be present for an iron object to rust?
For the oxidation of iron to occur, that is for ferric oxide to form, there must be oxygen present. There must also be water present.
Which must be present for a piece of iron to rust?
Rusting is the reaction of iron with oxygen in the presence of water.
What two substances causes rusting?
Rust is a chemical change and indicates a reaction do to the dramatic color change. It is the result of an oxide. So, there are NO substances needed for steel to rust. Even though steel itself is an alloy. :P However, you do need one element: OXYGEN!==========================Answer #2:Rust is iron oxide. In order for it to form,iron and oxygen must be present. Iron isan essential component of steel.
What happens when air is combined with substances like iron and water?
Air, iron and water will cause the iron to rust.

Why does an iron nail rust?
Iron present in the nail oxidizes in oxygen to form the iron oxides
Would a wheel barrow be magnetic if it had rust on it?
if rust is forming on a wheelbarrow, it is already magnetic. Rust is Iron Oxide, and a wheelbarrow must be made of iron if there is rust on it. Iron is always magnetic, so an iron wheelbarrow would be magnetic regardless of whether it had no rust or lots of rust on it.
What is the metal that needs to be present for rust to occur?
FE or Iron
What happens to iron when it gets wet?
When iron gets wet or comes into contact with water, it is likely to rust. However, some iron products are coated with substances that help prevent rust.
Why do weather rocks have rust streaks?
Some weathered rocks have rust streaks due to the iron content in the rocks. When rocks that have ferrous iron are weathered there will be rust streaks present.
Why do some weathered rocks have rust streaks?
Some weathered rocks have rust streaks due to the iron content in the rocks. When rocks that have ferrous iron are weathered there will be rust streaks present.
