What happens to the element in iron ore when the ore is mixed with carbon and heated?
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.
How can we reduce your carbon footprint?
If you want to reduce your carbon footprint, you can reduce your emissions of CO2 (carbon dioxide) into the atmosphere.
What ways are there to reduce extracting metals?
If you take iron ore, which is iron oxide, and heat it with coal (carbon) you end up with Iron and carbon dioxide. This process is called reducing. This works for most common metals like iron and copper but does not work for aluminium. This must be reduced by electrolysis because it is too reactive for carbon. There are some other limited processes for reducing of ores of rarer metals.
What is the word equation for making iron in a blast furnace?
Overall Fe2O3 + 3CO → 2Fe + 3CO2 In words, iron oxide reacts with carbon monoxide to produce iron and carbon dioxide. However it starts with 2 C + O2 → 2 CO. Carbon reacts with oxygen to produce carbon monoxide. Then 3 Fe2O3+ CO → 2 Fe3O4+ CO2 the carbon monoxide reduces the iron. Then the reaction continues to reduce more iron Fe3O4 + CO → 3 FeO + CO2 Eventually the iron is reduced to pure iron by more carbon monoxide as the temperature increases FeO+ CO → Fe + CO2 There are other side reactions.
How much carbon is in pure iron?
If it is pure iron then by definition there is no carbon or anything else present in it, just iron.
What is coke for in a blast furnace?
the Coke supplies carbon monoxide to reduce the ore in a blast furnace and supplies heat to melt the iron.

What substance in the iron extraction process reduces iron oxide to iron?
It is carbon (in the form of coke) that is added to blast furnaces to reduce iron oxide and recover the iron. This is the usual explanation, though most believe that it is the action of carbon monoxide that is involved. The equation for the reaction between iron oxide and carbon that produces iron and carbon monoxide is this one:2Fe2O3 + 3C → 4Fe + 3CO2
What happens when carbon monoxide is passed over red hot iron at 120c?
It would cool the iron. Iron is red hot at about 700 C
Can carbon monoxide be involved in the extraction of iron from hematite?
YES!!! In the Blast Furnace. CO is a powerful reducing agent , so it will reduce haematite to iron. In the Blast furnace, CO2 is formed from the thermal decomposition of limestone(flux). However because there is an excess of carbon (C) in the form of coke, the coke and CO2 combine to form CO (Carbon Monoxide). The carbon monoxide then reduces the haematite to iron, releasing CO2 in the process. The C , CO and CO2 then react in a cyclic manner inside the furnace. 3CO + F2O3 = 2Fe+ 3CO2
Iron melt at about 1700 degree Celsius. why all carbon in it does not burn out at that temperature?
Carbon can essentially dissolve in molten iron. Carbon only leaves iron if it is exposed to oxygen to make carbon dioxide. This happens in the process of converting iron to steel where the carbon content is controlled to desirable levels.If we heat the carbon in absence of oxygen, it will not be oxidized to carbon bi oxide. When you heat the Iron it melts. Through carbon is ready to get burn, it can not burn in the absence of oxygen and so it remains as carbon only. All around the carbon atoms, there are Iron atoms and as such it can not be converted to carbon bi oxide. It means if heated carbon is surrounded by iron atoms, it will not be oxidized and after cooling, it will remain as carbon only.
Does iron have much carbon in it?
iron has no carbon in it if it is pure iron
How can we reduce your carbon footprint?
If you want to reduce your carbon footprint, you can reduce your emissions of CO2 (carbon dioxide) into the atmosphere.
How do whales reduce carbon?
Whales don't reduce carbon .

What are the chemical formulas for iron ores?
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
