QUESTION 5 The correct name for Fe2O3 is O iron (III) oxide O iron oxide (III) O iron oxide O diiron trioxide
Iron (III) oxide can react with aluminum metal to produce aluminum oxide and iron metal This is called the thermit reaction and it produces so much heat that it can be used for incendiary bombs and for welding. How many grams of aluminum oxide will be produced by the reaction of aluminum with 45.8 g of iron(III) oxide?
(b) Draw a Born-Haber cycle for the Lithium telluride, clearly label the thermochemical data that would be required for each stage. (5) thium telluride, clearly label the diagram showing the (5 points)
Iron (II) oxide and iron (III) oxide …. A. have the same chemical formulas. B. have the same ratio of iron atoms to oxygen atoms. C. are both covalent molecules. D. None of the above are correct.
In place of iron(III) oxide in the thermite reaction in the previous problem, chromium(III) oxide can be used in its place, generating chromium metal and aluminum oxide as products. Calculate DrxnH and DrxnS for this thermite-type reaction. Assume standard conditions
Blast furnaces extract pure iron from the iron(III) oxide in iron ore in a two step sequence. In the first step, carbon and oxygen react to form carbon monoxide: 2C (s) + O2 (g) → 2CO (g) In the second step, iron(III) oxide and carbon monoxide react to form iron and carbon dioxide: Fe2O3 (s) + 3CO (g) → 2Fe (s) + 3CO2 (g) Write the net chemical equation for the production of iron from carbon, oxygen and iron(III) oxide....
