The thermite reaction involves aluminum and iron(III) oxide forming aluminum oxide and liquid iron. Calculate the heat released in kJ per gram of aluminum reacted. The standard enthalpy of formation for liquid iron is 12.40 kJ/mol.
In the thermite reaction, iron (III) oxide is reduced by aluminum to give molten iron, Fe2O3 (s) + 2 Al (s) --> 2 Fe (l) + Al2O3 (s) If you begin with 10.0 g of Fe2O3 and 20.0 g Al, Which reactant is limiting? What mass of Fe can be produced? What mass of the excess reactant remains after the limiting reactant is consumed? Set up an amounts table for this problem.
The following reaction takes place at high temperatures. Solid chromium(III) oxide reacts with liquid aluminum to give liquid chromium and liquid aluminum oxide. Write a balanced chemical equation (include the states of matter): If 105.2 g of chromium(III) oxide and 60.6 g of aluminum are mixed and reacted until one of the reactants is used up, how much (in g) of chromium metal will be produced? How much (in g) of the excess reactant remains?
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?
The highly exothermic thermite reaction, in which aluminum reduces iron (III) oxide to elemental iron, has been used by railroad repair crews to weld rails together. 2Al(s) + Fe2O3(s) 2Fe(s) + Al2O3(s) AH = -850 kJ What mass of iron is formed when 725 kJ of heat are released?
The highly exothermic thermite reaction, in which aluminum reduces iron(III) oxide to elemental iron, has been used by railroad repair crews to weld rails together. 2Al(s) + Fe2O3(s) - 2Fe(s) + Al2O3(s) AH=-850 kJ What mass of iron is formed when 725 kJ of heat are released?
Before arc welding was developed, a displacement reaction involving aluminum and iron(III) oxide was commonly used to produce molten iron (the thermite process). This reaction was used, for example, to connect sections of iron railroad track. Calculate the mass of molten iron produced when 1.52 kg of aluminum reacts with 21.6 mol of iron(III) oxide. Enter your answer in scientific notation.
Write a balanced chemical equation based on the following description: the reaction of powdered aluminum and powdered iron(III) oxide produces solid aluminum oxide and liquid iron metal
For the following reaction, 55.7 grams of iron(III) oxide are allowed to react with 23.5 grams of aluminum. iron(III) oxide(s) + aluminum(s) — aluminum oxide(s) + iron(s) What is the maximum amount of aluminum oxide that can be formed? grams What is the FORMULA for the limiting reagent? What amount of the excess reagent remains after the reaction is complete? grams
