iron has no carbon in it if it is pure iron
There are two equations, the first to describe how the carbon reacts with the oxygen in the air,Carbon + Oxygen ---- Carbon Monoxideor2C + 02 ---- 2COThe second describes how the carbon monoxide reacts with the iron oxide forming carbon dioxide and pure iron,Carbon Monoxide + Iron Oxide ---- Iron + Carbon Dioxideor3 CO + Fe2O3 ---- 2 Fe + 3 CO2Another might beiron oxide + carbon --> carbon dioxide + iron
pig iron or cast iron having 4.5% carbon as an impurity wroght iron having 0.15% of carbon steel having 1% carbon
Yes, it has iron, chromium, carbon and nickel.
If it is pure iron then by definition there is no carbon or anything else present in it, just iron.
The oxygen burns off the carbon and other non-metal impurities.
If you want to add carbon to an iron alloy all you need to do is melt the iron in the presence of carbon. The carbon will be absorbed and alloy automatically. Carbon can also be added to a thin layer of the surface of a piece of solid iron alloy without melting simply by heating the iron red hot and covering it with carbon for a period of time.
cast iron contain a considerable amount of carbon
Both of these are oxides (of carbon and iron respectively).
Steel is the alloy of iron and carbon.
Cast iron has greater than 2.1% carbon.
Iron ores most often contain iron combined with oxygen. The carbon comes from a material called coke, which is made from coal. When heated, the carbon reacts with oxygen in the ore, leaving the purified iron metal behind.
