oxygen and water
Usually heat is needed. but this can happen through osmosis as well.
It has high affinity for electrons.
Water and oxygen are needed.
Oxygen is a very important agent needed for rusting and decaying to take place. Oxygen binds with the surface and creates water while breaking down the substance.
Rusting typically requires the presence of oxygen in the gas phase, as this initiates the oxidation reaction that leads to the formation of rust. Additionally, moisture or water is also needed for the process of rusting to occur, as it helps accelerate the oxidation of the metal.
Corrosion is a slow process of rusting of the outer surface of the metals.in the presence of both o2 and h20 the surface of a piece of iron will react to produce iron hydroxide,this is really a flaky material that is pushes away from the pure iron below.
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.
Oil leaves a film on the surface that repels water and air, the two things needed for rust.
A great amount of material is needed to earn a theology degree. Most of the material consists of: Calculus, Chemistry, excellent English, and Physics.

Oxygen is not needed in fermentaion.
What is rusting?Rusting is corrosion of iron.1) Corrosion (in here) means low oxidation- as a metal turns to the metal oxide.2) The more reactive the metal-thequicker this happens.3) The oxide is usually weaker than the metal- rusty things tend to fall to bits.ALSO, water and oxygen are needed for rusting to happen inthe first place.EQUATION: IRON+WATER+OXYGEN->IRON OXIDE (rust)How iron is prevented from rust?(SORRY, NOT REALLY SURE ABOUT THIS QUESTION; COULD YOU BE MORE SPECIFIC PLEASE)
