Nothing unless they are heated. If they are heated it will become iron oxide. Which is the same material that we find the ground

When iron and oxygen combine to form rust what is are the reactants?
What happens when iron and oxygen react?
What is occurring during rusting iron?
Rusting needs iron, water and oxygen. Rusting is an example of an oxidation reaction. this is when oxygen is added to the substance. Rust flakes off the iron exposing more metal to corrode. Rusting happens faster when the water added is salty or acid rain. when cars rust they are usually scrapped because it makes iron weaker. iron + oxygen + water = (should be an arrow but dis shud doo) Hydrated iron (lll) oxide. hpe it was useful :)
Why does an iron nail gain weight on rusting?
Oxygen is being incorporated into the surface, forming iron oxide. The added mass is oxygen.
What happens to the concentration of oxygen in the water when the sewage is added?
The concentration of oxygen decrease.
What happens to the concentration of oxygen in water when the sewage is added?
The concentration of oxygen decrease.
What chemical reaction happens when iron combines with oxygen?
rust?
What happens to iron oxygen in the presence omoisture?
it rusts and then rotten
What happens to iron powder and salt mixture when it is added to water?
The salt dissolves in the water and the iron does not.
Will iron lose weight while rusting?
No. In fact, iron will gain weight because of the added weight of the oxygen.
What happens when materials containing iron is exposed with water and oxygen?
oxidation
Why does iron weigh more after it rusts?
because the iron bonds with oxygen, so the weight becomes the original weight of iron plus the original weight of Oxygen.
When oxygen is blown into pure iron to remove impurities Wont it react with Iron itself to give iron oxide?
Oxygen is not blown into pure iron, it is blown into molten iron ore (many impurities) and coke has been added to the mix as well. the coke reacts with the impurities and the oxygen to purify the iron ore.
