Nothing unless they are heated. If they are heated it will become iron oxide. Which is the same material that we find the ground
Iron oxide is formed when iron, nitrogen, and oxygen are added together. It is a chemical compound that is commonly known as rust.
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 :)
The reactants in the formation of rust are iron (Fe) and oxygen (O2). When iron reacts with oxygen in the presence of water or moisture, it forms iron oxide, commonly known as rust.
rust?
The concentration of oxygen decrease.
The concentration of oxygen decrease.
The iron and sulphur split because the iron sinks and the sulphur floats so you can separate the mixture
oxidation
No. In fact, iron will gain weight because of the added weight of the oxygen.
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.
Oxidation. Water, oxygen, and metal.
When iron is burnt, it combines with oxygen to form iron oxide (rust). This increase in weight is due to the added oxygen atoms bonded to the iron atoms, making the total weight of the iron and oxygen combined greater than that of the unburnt iron alone.
