WebElements Periodic Table Iron reactions of elements

Reaction of iron with air. This does not protect the iron surface to further reaction since it flakes off, exposing more iron metal to oxidation. This process is called rusting and is familiar to any car owner. Finely divided iron powder is pyrophoric, making it a fire risk. On heating with oxygen, O 2, the result is formation of the iron oxides Fe 2 O 3 and Fe 3 O 4.

2. Extraction of Iron and Steelmaking Doc Brown

Iron ore is used to make iron and steel eg haematite and magnetite. Iron is produced (extracted) in a blast furnace by reducing iron oxides with carbon and it is the carbon that removes the oxygen from the iron oxides the carbon is known as the reducing agent. Coke is a cheap and readily made reducing agent.

What is the balanced equation when Iron(3) oxide reacts

So now coming to the solution this is the balanced equation Iron is Fe2O3 right?? Fe2O3 3CO = 2Fe 3CO2. For solving this first of all you figure out the formula of iron(3)oxide so you look at the periodic table as you said valency of iron is 3 positive because metals are always positive and oxygen's valency is 2 (negative because non-metal).
