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
In order to extract iron from iron oxide, the iron ore is placed in a blast furnace where oxygen is supposed to be extracted from it. In this process, iron oxide combines with carbon to create iron and carbon dioxide, which is in it's gaseous form.
It is easier to obtain a metal from its oxide as compared to its sulphides and carbonates. So the metal sulphides & carbonates must be converted to metal oxides to ease the extraction

when wate ris adde to metallic oxide it forms a hard substance
Copper Oxide
An oxide I reckon.ExamplesAluminum oxideFerric oxide (aka rust)

calcium oxide --> calcium + oxygen
The process is called oxidation in general and in many cases the result is an oxide.
Yes. Calcium oxide is a compound which is a type of pure substance.
Novocane or nitrous oxide.
oxidition
No, Aluminum oxide is a pure substance.
Oxygen oxide is not a real substance.
when wate ris adde to metallic oxide it forms a hard substance
sodium oxide: 1132oC magnesium oxide: 2852oC
it is an iron oxide
Sources of sulfur oxide pollution are engine combustion of fossil fuels, & metal extraction from ore. Water is the main sink for sulfur oxide.
