What else can I help you with?
When oxygen is blown into pure iron to remove impurities Wont it react with Iron itself to give iron oxide?
Oxygen is not blown into pure iron, it is blown into molten iron ore (many impurities) and coke has been added to the mix as well. the coke reacts with the impurities and the oxygen to purify the iron ore.
How does calcium carbonate purify iron?
Calcium carbonate (limestone) is used in blast furnaces to capture impurities and form a slag that floats above the molten iron to keep the impurities from mixing back into the iron.
What happens when iron react with air?
When iron reacts with air, they form ferric oxide.
What happen in the iron fillings and sulfur powder if they heat together?
The iron and sulfur react to form the compound iron sulfide.
Purest form of iron is?
Wrought iron is purer than pig iron. When purifying iron ore in a furnace furnace, air is passed through a "charge" of iron ore, limestone, and some form of carbon, charcoal or coal. This "smelting" process is a chemical change: the molten iron produced is tapped from the furnace as "pig" iron. Pig iron is iron with a high carbon content as well as some sulfur. Due to it's impurities pig iron has a lower melting point and is acceptable for casting but not forging. Wrought Iron is made much the same way with the exception of the carbon source being used is coke, a purified form of bituminous coal. Coke being a purer form of carbon burns smokeless and imparts little to no carbon to the iron allowing more impurities to burn out. This byproduct is wrought iron. Wrought iron is acceptable for either casting or forging.
When oxygen is blown into pure iron to remove impurities Wont it react with Iron itself to give iron oxide?
Oxygen is not blown into pure iron, it is blown into molten iron ore (many impurities) and coke has been added to the mix as well. the coke reacts with the impurities and the oxygen to purify the iron ore.
Was does iron react with?
Iron can react with water in the presence of air and form rust.
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.
Does iron react to other substances?
Yes because it reacts with Sulphur(S) to make Iron Sulphide a totally new substance.
How does calcium carbonate purify iron?
Calcium carbonate (limestone) is used in blast furnaces to capture impurities and form a slag that floats above the molten iron to keep the impurities from mixing back into the iron.
If iron and bromine react what compound will it form?
Iron and bromine will form iron(III) bromide, which has the chemical formula FeBr3.
What is the function of limestone in the furnace?
Limestone is added to the furnace as a flux to help remove impurities from the iron ore during the iron-making process. It reacts with the impurities to form slag, which can be easily removed from the molten iron.
How do halogens react with air?
Halogens react with air to form metal halides. For example, chlorine will react with iron to form iron(III) chloride. Halogens are highly reactive and will readily form compounds with many elements in the air.
Does iron react with chlorine to form iron chloride?
Yes, iron can react with chlorine to form iron chloride. Iron has multiple oxidation states, with the most common being iron(II) and iron(III) chloride when reacted with chlorine gas.
What happens when iron react with air?
When iron reacts with air, they form ferric oxide.
Will zinc oxide and iron react?
No, zinc oxide and iron will not react with each other under normal conditions. Zinc oxide is a stable compound and does not readily react with iron to form a new compound.
Does iron sulphate react with sulphuric acid?
Iron sulfate (ferrous sulfate) does not react with sulfuric acid because it is already in the form of a salt with sulfuric acid - FeSO4. However, iron metal can react with sulfuric acid to form iron sulfate and hydrogen gas.
