What chemical process is used for obtaining a metal from its oxide?
The chemical process used for obtaining a metal from its oxide is reduction. This process involves the removal of oxygen from the metal oxide, typically by using a reducing agent such as carbon or hydrogen, to yield the pure metal.
Why is zinc not extracted from zinc oxide through reduction using carbon monoxide?
Magnesium is a more reactive metal therefore for using any extraction method you would have to use electrolysis, which is expensive. Whereas for zinc it is extracted from its ore chemically by reduction using carbon. When an ore is reduced you are taking the oxygen out of the metal, this is because carbon can only take the oxygen away from metals which are less reactive than carbon its self. For example, zinc oxide is reduced in a blast furnace to make zinc.
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.
When iron oxide is reduced?
When iron oxide is reduced, the iron atoms gain electrons to form elemental iron. This process usually involves the removal of oxygen from the iron oxide through a chemical reaction, often using a reducing agent such as carbon monoxide or hydrogen. The reduction of iron oxide is an important step in the production of iron and steel.
Why can carbon be used to extract copper oxide?
Mg is a highly electro positive metal and hence has high affinity towards more electronegative element oxygen and thus ,oxide of Mg is very stable and can not be reduced by carbon (Carbon has less affinity than Magnesium towards oxygen). On the other hand , Zn being moderately strong electro positive metal , it has less affinity towards the more electronegative oxygen atom and its oxide is not very stable and hence can be reduced by Carbon easily (carbon has greater affinity than Zinc towards oxygen).
If Iron oxide is reduced what do you get?
If iron oxide is reduced, you will get elemental iron. This is because reduction is a chemical reaction in which the oxidation state of an element is decreased, resulting in the removal of oxygen from a compound like iron oxide.
What chemical process is used for obtaining a metal from its oxide?
The chemical process used for obtaining a metal from its oxide is reduction. This process involves the removal of oxygen from the metal oxide, typically by using a reducing agent such as carbon or hydrogen, to yield the pure metal.
What are reagents which could reduce zinc oxide?
Zinc oxide can be reduced using carbon monoxide or hydrogen gas at high temperatures. Another reagent that can reduce zinc oxide is carbon in the presence of a reducing agent such as carbon monoxide or hydrogen.
How do you extract metal from its oxide?
Metal can be extracted from its oxide by a process called reduction. This involves using a reducing agent such as carbon or hydrogen to remove the oxygen from the metal oxide. The metal is then left in its elemental form.
Why is zinc not extracted from zinc oxide through reduction using carbon monoxide?
Magnesium is a more reactive metal therefore for using any extraction method you would have to use electrolysis, which is expensive. Whereas for zinc it is extracted from its ore chemically by reduction using carbon. When an ore is reduced you are taking the oxygen out of the metal, this is because carbon can only take the oxygen away from metals which are less reactive than carbon its self. For example, zinc oxide is reduced in a blast furnace to make zinc.
What type of chemical reaction is always involved in the extraction of metal from its ore?
The extraction of metal from its ore typically involves a reduction reaction, where the metal oxide in the ore is reduced to the elemental metal using a reducing agent such as carbon or hydrogen. This reduction reaction is necessary to separate the metal from the impurities in the ore.
How are metals that are less reactive than carbon extracted from their oxides?
Metals less reactive than carbon, such as copper and silver, are extracted by reduction using carbon as a reducing agent. The metal oxide is heated with carbon (in the form of coke) to form carbon monoxide, which then reduces the metal oxide to the pure metal and carbon dioxide.
How copper can be extracted from copper(II)oxide using carbon?
Copper can be extracted from copper(II) oxide by heating a mixture of copper(II) oxide and carbon. The carbon, in the form of charcoal or coke, reduces the copper oxide to form copper metal and carbon dioxide gas. The reaction can be represented as: CuO + C -> Cu + CO2.
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 chemical name of CO using the stock system?
The chemical name of CO using the stock system is carbon(II) oxide.
