Iron rusts when it reacts with Oxygen. When iron reacts with oxygen, reddish-brown colored iron-oxides are formed. This is called rust Answer:
Iron can react with oxygen at many rates some cause red iron oxide (rust) others black iron oxides. Rusting is a slow process which is usually regarded as safe unless the rusting iron is essential for mechanical strength in a system. Iron burns in fireworks to create coloured flames. Steel wool (essentially iron fibers) can burn in air causing injury and igniting other materials. Iron burns when heated in an acetylene flame with excess oxygen resulting in molten iron spray. Iron burns violently in a pure oxygen atmosphere.
Aside: When iron "unburns" (rust changes back to iron in a thermite reaction) it can be very dangerous and destructive.

Where does the oxygen come from that is reacting with a piece of burning iron?
When oxygen is reacting with iron it generally comes from the air, but it can also come from oxygen disolved into water. There are other ways it can occur but I do not know these. But unless it is in a vacuum, the oxygen comes from the surrounding environment like air or water.

Why do people have certain symptoms with cancer treatments?
There are many different types of cancer, so there are many different ways of reacting with the symptoms.
What are two ways that organisms changed Earth's surface?
Many bacteria were protected from the ultraviolet radiation by the salt water in the ocean. In the sea bacteria made oxygen. Some of that oxygen escaped into the air and caused the earth surface to rust. After billions of years all the iron rusted in the sea and on the land. Then, when the oxygen was no longer used up in rusting iron, oxygen began to build in the atmosphere. The oxygen in the air blocked the deadly ultraviolet radiation from the sun, allowing life to evolve and migrate onto the land. Plants evolved and covered the earth and made it green.

What are 5 ways to prevent iron from rusting?
Keep iron surfaces dry to prevent moisture from reacting with oxygen in the air. Apply a protective barrier such as paint, oil, or wax to create a barrier between the iron and the environment. Use a rust-resistant coating like galvanization or stainless steel for long-term protection. Store iron items in a cool and dry environment to minimize the chances of rust formation. Regularly clean and inspect iron surfaces for any signs of rust, addressing any issues promptly.

What is a waste product from iron ore?
A waste product from iron ore processing is tailings, which are fine-grained materials left over after the extraction of iron from the ore. Tailings are typically stored in tailings ponds or disposed of in other ways to prevent environmental contamination.
Why does iron nail is exposed to nitrogen not rust?
the corrosion agents for iron are moisture and oxygen. Boiling the water removes all of the dissolved gases, including oxygen. The absence of oxygen in the water is maintained by the layer of oil. That prevents the iron from rusting.
How does one react when they feel pain?
There are many different ways of reacting when pain is felt. Simply put, pain is the human brain reacting to stimuli by sending various signals to one's nerves.
What are the ways of preventing rusting?
Rusting is the oxidation of iron. To prevent rusting you must prevent oxygen from coming into contact with the product. This is normally acheived by applying a barrier of oil in working environments. Products are available for storing materials for long periods to avoid rusting. These have a more waxy nature than oil and would not be suitable to use to stop rusting in a mechaincal item. Of course if you want to prevent rusting and for it to look nice. various paints and lackers can be applied. Chemical coatings can also be applied to prevent rusting. Or simply keep the item clean and dry and rusting can be slowed.
