Oxygen and water...... :)
Rust forms when iron or iron alloys are exposed to oxygen and moisture. The presence of oxygen allows for the oxidation of iron, leading to the formation of iron oxide (rust).
because you need to have solid iron for it to rust
Nitrogen is not necessary.
No, rust is not a homogeneous mixture. Rust is a chemical compound that forms when iron reacts with oxygen in the presence of water or moisture. It is a solid metal oxide compound, not a homogeneous mixture of different substances.
No they will not get rust they are not iron to get rust. only iron get rust.
Dissolved Oxygen and liquid water- rust is hydrated iron oxide though you could get some rust with another oxidiser like ferric ions (a type of iron ion) which breaks up water to add oxygen to corrode the iron. Extra components to help rust are salts and temperature and a supply of oxygen.
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.
Iron does rust by reacting with oxygen.
Rust forms when iron or steel is in contact with oxygen and water. This combination leads to the oxidation of iron, forming iron oxide (rust). Other factors like salt in the environment can accelerate the rusting process.
Liquids do not rust, iron does, rust is Hydrated Iron (III) oxide, so the only substance which can rust iron is water
Water and oxygen
The iron would not rust, because calcium chloride is a desiccant. For rusting to occur there are two vital components: water and oxygen. Since calcium chloride is a desiccant, it would absorb the water, so rusting would not occur.
