Homework Help: Chemistry

I looked and could not find anything on iron smelting? Could you explain to me why it is a chemical process?

Iron ore is a chemical compound, it has to be decomposed into iron + other.

Surely you jest!!! I went to www.google.com and typed in Iron smelting and got over 1 million hits. The first three were all I needed to use. Try again please. Iron smelting is the reduction of iron ore, usually as the oxide, to iron. So we start with iron oxide and reduce it to iron. We had Fe2O3 or Fe3O4 or FeO and reduce it to Fe. That is a chemical change because we have changed the composition of the material in the process. Any carbon there is converted to CO2 (another chemical change) etc. I hope this helps. Please go to google and learn to use it. It will be well worth your time.
