What compound is formed when copper is burned?

Cooper get oxidised to copper oxide when burned in air.


Iron can be produced by reacting iron oxide with carbon in a blast furnace. What type of reaction produces the iron?

We see a reduction reaction stripping the oxygen from iron in a blast furnace. Carbon in the form of coke is added to the furnace to facilitate the reaction. This is the primary chemical reaction that is used to produce iron on an industrial scale. In the reaction, iron oxide and carbon yield iron and carbon dioxide. It looks like this in its balanced form: 2Fe2O3 + 3C → 4Fe + 3CO2 It is generally thought that carbon monoxide is the actual reducing agent that "steals" the oxygen from the iron to leave it in its elemental state, but what is posted above is the commonly published information.


What is the difference between iron oxide and ferrite?

Oxidation is the process by which iron oxide, and all other forms of rust, occur. Oxidation is the process by which a substance containing a metal reacts with the oxygen in the air. Chrome, for example, rusts perfectly transparent. This property is what keeps chrome shiny. I thin layer of ChromeOxide develops over the surface of the object, protecting the rest of the chrome from further oxidization.


How is iron made from iron oxide?

Iron oxide is mixed with coke(Carbon) and Limestone(Calcium Carbonate). This mixture is named 'sinter'. It is loaded into the top of the blast furnace. Whereupon a BLAST of hot air is blown in at the bottom through 'tuyeres'. The temperature is about 1100 oC . This is a 24 hour , 7 days a week process. It does not stop unless the furnace is to be closed down for maintainance, e.g. checking the silicon brick lining, and checking the cooling water jacket is water-tight etc., This hot air does two things;- #1 it combines with the coke to form carbon monoxide (CO) #2 it thermally decomposes the limestone to calcium oxide and carbon dioxide. Because of the 'shortage' of oxygen in the furnace and an excess of coke , the carbon dioxide also decomposes to form carbon monoxide. The carbon monoxide is a very good reducing agent and reduces the iron ore to form iron. Fe2O3 + 3CO = 2Fe + 3CO2 The CO2 can then re-circulate to form more CO. The calcium oxide formed from the decomposition of limestone reacts with the impurities , mainly sand (silicon dioxide) to form 'slag' (Calcium silicate ' CaSiO3). So you have two products viz. 'pig' iron and 'slag'. The 'pig' iron has the carbon levels adjusted in a BOS plant to make steels. and the 'slag' is used to make 'breeze' blocks for building and for road surfaces. NB THe coke(carbon) is obtained from coal. Coal is baked in coke ovens to release the unwanted gases e.g. sulphur dioxide, ammonia, hydrogen sulphide , methane etc., to form coke. These released gases are 'captured' and sold to make other chemicals. e.g. paints, fertilizers. etc., Hope that helps!!!!


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.

Does iron ore slag sink to the bottom of the blast furnace?

Slag is the waste which is skimmed off the top of the molten iron that comes out of the blast furnace. It is a mixture of calcium and magnesium compounds, plus other impurities such as iron oxide, but is mainly calcium silicate. The formula for calcium silicate is CaSiO3.


What is use of mud carbon in blast furnace?

Mudgun is hydraulically operated machine that is used to close the tap hole of the blast furnace after draining out the metal / slag from the furnace from time to time. It is heavy equipment and the most critical of all the equipments used in blast furnace. The failure of the machine will lead to shut down of the furnace to close the tap hole.

Why can't aluminium be extracted from aluminium ore using a blast furnace?

Because it is more reactive then carbon to be extracted in a blast furnace. Remember carbon is the reducing agent and for it to work the metal being extracted has to be lower in the reactivity series, e.g. iron


What is an oxidized element?

An "Oxidised Element" is any element that has reacted with Oxygen to form a compound. The compound suffixes of these compounds will be "Oxide, Monoxide, Dioxide, Trioxide" etc. Some examples of oxidised elements:Iron + Oxygen --> Iron OxideCarbon + Oxygen --> Carbon DioxideMagnesium + Oxygen --> Magnesium Oxide


If lead oxide is heated with magnesium?

when it reacts with leadoxide it become magnesuim oxide. this is because they lead and magnesuim have undergone a REDOx (reduction and Oxidation). the lead has been reduced and they magnesium has be oxidised!!!!!


When sulphur oxide or nitric oxide is combined with moisture in the air then what is formed?

Sulfur dioxide and nitrogen dioxide combine with water to make acid rain. Nitric oxide is neutral but is rapidly oxidised to nitrogen dioxide.


Refining process that occurs in a blast furnace?

The refining process is actually a REDUCTION process. The iron ore ( oxidised iron ) is reduced in the Blast Furnace to IRON. Three substances are mixed and added to the Blast Furnace. They are Iron Ore (Iron(III) Oxide ; Fe2O3) Coke (Carbon ; C) Limestone ( Calcium carbonate ; CaCO3) A Blast of Hot Air is sent in from the bottom (O2) The heat makes the limestone decompose to calcium oxide(CaO) and carbon dioxide(CO2) The Carbon then reacts with the carbon dioxide and also the air to form carbon monoxide. CO2 + C = 2CO & "C + O2 = 2CO (4CO) It is the Carbon Monoxide (CO) that reacts with iron ore to form iron. as carbon monoxide is a powerful reducing agent. 2Fe2O3 + 4CO = 4Fe + 4CO2 (Not Balanced) As a secondary reaction the calcium oxide reacts with the impurities in the iron oxide (viz. sand ; SiO2) to form 'slag' (calcium silicate) . CaO + SiO2 = CaSiO3 (slag). Calcium silicate is used top make road surfaces, and 'breeze' blocks for building. The iron that is collected is still impure, and whilst liquid hot, is placed in a BOS plant with an oxygen lance, to oxidise any remaining impurities, viz. sulphur, (to sulphur dioxide) and phosphorus(to Phosphorus oxide). The carbon impurity ( to carbon dioxide) is controlled at this stage in order to make steel , which contains about 0.1% to 2% carbon , depending on the nature of the steel.
