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
Carbon, typically in the form of coke or coal, is used to reduce iron oxide (Fe2O3) to iron in the extraction process. The carbon reacts with the oxygen in the iron oxide to form carbon dioxide gas and elemental iron.

Which element are formed when molten alumunium oxide is electrolysed?
When molten aluminum oxide is electrolyzed, it forms aluminum metal at the cathode and oxygen gas at the anode. This process is used in the extraction of aluminum from bauxite ore.
What is the word equation for the extraction of iron from the ore iron oxide?
Iron oxide + carbon monoxide -> iron + carbon dioxide
Which substance is formed when impurities in the ore react with calcium oxide?
When impurities in the ore react with calcium oxide, they form slag. Slag is a byproduct of the smelting process and is used to separate impurities from the metal being produced.
Is burning magnesium oxide a chemical change or physical?
Burning magnesium oxide is a chemical change because it involves a chemical reaction where the magnesium oxide is converted to a new substance (magnesium oxide reacts with oxygen to form magnesium oxide). This process involves the breaking and forming of chemical bonds.
What chemical combination of a substance with oxygen is?
Combining a substance with oxygen typically results in oxidation. This chemical combination forms new compounds known as oxides. The process involves the transfer of electrons from the substance to oxygen, resulting in the release of energy.
Can copper be extracted from its compounds using carbon?
Yes, copper can be extracted from its compounds using carbon through a process called smelting. The carbon reduces the copper oxide to metal, forming carbon dioxide as a byproduct. This process is commonly used in the extraction of copper from ores such as copper oxide.
What is the word equation for extraction of calcium from calcium oxide by electrolysis?
The word equation for the extraction of calcium from calcium oxide by electrolysis is: Calcium oxide (solid) -> Calcium (liquid) + Oxygen gas.
Which element are formed when molten alumunium oxide is electrolysed?
When molten aluminum oxide is electrolyzed, it forms aluminum metal at the cathode and oxygen gas at the anode. This process is used in the extraction of aluminum from bauxite ore.
Is calcium oxide is a pure substance?
Yes. Calcium oxide is a compound which is a type of pure substance.
What is the best anesthetic for wisdom teeth extraction?
Novocane or nitrous oxide.
What is it called when when oxygen binds to a substance?
The process is called oxidation in general and in many cases the result is an oxide.
What is the word equation for the extraction of iron from the ore iron oxide?
Iron oxide + carbon monoxide -> iron + carbon dioxide
Is oxygen oxide an acid or a base?
Oxygen oxide is not a real substance.
Which substance sodium oxide or magnesium oxide has higher melting point?
sodium oxide: 1132oC magnesium oxide: 2852oC
What substance is O2 converted into as it accepts electron?
O2 is converted into H2O (water) as it accepts electrons during the process of cellular respiration.
Which substance is formed when impurities in the ore react with calcium oxide?
When impurities in the ore react with calcium oxide, they form slag. Slag is a byproduct of the smelting process and is used to separate impurities from the metal being produced.
The extraction of aluminum from its ore requires a great deal of?
energy. The process, known as the Hall-Héroult process, involves electrolysing aluminum oxide (Al2O3) to extract pure aluminum. This requires a significant amount of electricity to separate the aluminum from the oxygen in the ore.
