A. iron oxide is reacted with water.B. iron oxide is reacted with CO2.C. iron oxide is reacted with carbonD. iron is coated with aluminum.thanks!
D. this would be a thermite reaction. fe2o3+2al2fe+al203 so that produces pure (alpha) iron and aluminum oxide we were taught in materials of industry that you could also react molten steel with oxygen to burn off the carbon. can the answer be C D? Edit: straight out of my materials book: Iron could be removed from it's ore by trading aluminum or magnesium for the iron in the oxides. The equations for these reactions are: Al+Fe2O3-- Al2O3+fe 3Mg +Fe2O3 -- 3 MgO +2fe . the problem with using it as a refining technique is that the aluminum or magnesium must first be refined, and the cost would be prohibitive. One element that is more active thatn iron and is cheap and easy to get is carbon. The chemical equation for this reaction is (FeO or Fe2O3) + C -- Fe + CO so it seems to me that the answer should be C D
The correct answer is C. Iron oxide, mainly Fe2O3, is reduced with solid carbon in a blast furnace. For extra credit, the actual reactant in the process is carbon monoxide: C + O2 --- 2CO Fe2O3 + 3CO --- 2Fe + 3CO2
iron oxide is reacted with carbon
