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 is
an essential component of steel.
The 2 materials that are combined to cause rusting is Oxygen and air.
I hope this has helped!

Can you name two chemical changes?
Two examples of chemical changes are the rusting of iron and the combustion of gasoline. In chemical changes, new substances are formed due to the rearrangement of atoms.
How do you excelerate rust?
To accelerate rusting, you can expose the metal to moisture and oxygen, as these are the two key elements needed for the oxidation process that causes rust. You could also introduce salt or an acidic solution to speed up the rusting process. Additionally, increasing the temperature can also accelerate the rusting of metal.
What causes substances to combine in different ways to make other substances?
A chemical reaction causes substances to combine in different ways to make other substances.
WHICH two substance which expands on heaTing?
Two substances that expand when heated are water and mercury. Heating these substances causes their molecules to become more energized and move farther apart, leading to an increase in their volume.
Is rusting a oxidising process?
Oxidation is defined as the interaction between oxygen molecules and all the different substances they may contact, from metal to living tissue. Technically, however, with the discovery of electrons, oxidation came to be more precisely defined as the loss of at least one electron when two or more substances interact. Those substances may or may not include oxygen. (Incidentally, the opposite of oxidation is reduction - the addition of at least one electron when substances come into contact with each other.) Sometimes oxidation is not such a bad thing, as in the formation of super-durable anodized aluminum. Other times, oxidation can be destructive, such as the rusting of an automobile or the spoiling of fresh fruit.
What is the materials causing iron rusting?
Its the moisture which causes rusting of iron
Does iron change when it is moist?
It causes rusting
What substances rusts iron?
Rusting is possible in the presence of oxygen and water.
What causes a ring to turn your skin black?
Rusting

What causes artifacts to rust?
Rusting is the oxidation of iron in a humid environment.
What causes chemical weatering?
Chemical weathering is caused by chemical reactions in the substance, for example, when oxidation causes rusting.
What type of change such as burning or rusting causes a substance change?
chemical change
What causes substances to combine in different ways to make other substances?
A chemical reaction causes substances to combine in different ways to make other substances.
What kind of chemical causes rusting of iron?
The chemical that causes rusting of iron is oxygen in the presence of water. This process is known as oxidation, where iron reacts with oxygen to form iron oxide (rust) in the presence of moisture.
What are the best conditions for rusting?
The best conditions for rusting to occur are when iron or steel is exposed to moisture (such as water or humidity) and oxygen. The presence of these elements initiates a chemical reaction that leads to the formation of rust. Additionally, exposure to salt or acidic substances can accelerate the rusting process.
