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?
The following thermochemical equation is for the reaction of iron(III) oxide(s) with hydrogen(g) to form iron(s) and water(g). Fe2O3(s) + 3H2(g)— 2Fe(s) + 3H2O(g) AH = 98.8 kJ When 62.3 grams of iron(III) oxide(s) react with excess hydrogen(g), kJ of energy are Hint: An amount of energy is expressed as a positive number. The sign of AH in the thermochemical equation indicates whether the energy is absorbed or evolved. An automobile engine provides 523 Joules of work to push the...
