Iron is produced from an iron ore that contains the substance iron iii oxide

Raw material Contains Function; Iron ore (haematite) Iron(III) oxide (Fe 2 O 3): A compound that the iron is extracted from: Coke: Carbon (C) Used as a fuel and reacts to form carbon monoxide

    Sep 10, 2016 In this case, iron (III) oxide has a molar mass of 159.7 g mol ^(-1) and carbon monoxide has a molar mass of 28.01 g mol ^(-1). Right from the start, you should be able to tell that iron(III) oxide will be the limiting reagent because you have significantly more moles of carbon monoxide in 2.00 kg than moles of iron(III) oxide in 2.00 kg

    Iron ore isn't pure iron oxide - it also contains an assortment of rocky material. This wouldn't melt at the temperature of the furnace, and would eventually clog it up. The limestone is added to convert this into slag which melts and runs to the bottom. The heat of the furnace decomposes the limestone to give calcium oxide

    Aug 19, 2016 Approx. 15*g of metal. Moles of iron oxide, Fe_2O_3 = (21.6*g)/(159.69*g*mol) = 0.135*mol with respect to the oxide. But by the composition of the oxide, there are thus 2xx0.135*molxx55.8*g*mol^-1 iron metal = ??g. An extraordinary percentage of our budgets goes into rust prevention; iron(III) oxide is only part of the redox chemistry. Once you put up a bridge or a

    Not all the iron (III) oxide is reduced by carbon monoxide in this way. Between 20% and 30%of the iron is produced by direct reduction, when the ore is directly reduced by carbon. iron (III) oxide + carbon →iron + carbon monoxide Fe 2 O 3 + 3C →2 Fe + 3 CO In this reaction unburned carbon, not carbon monoxide, is the reducing agent
