Question
The thermite reaction is a very exothermic reaction; it has been used to produce liquid iron for welding. A mixture of 2 mol of powdered aluminum metal and 1 mol of iron(III) oxide yields liquid iron and solid aluminum oxide. How
many grams of the mixture are needed to produce 219 k) of heat?
Data:
AH;(Al(s)) = 0 kJ/mol
AH (Fe,O3 (s)) = -825.5 kJ/mol
AH (Fe(1)) = 12.4 kJ/mol
AH;(Al2O3 (s)) = -1675.7 kJ/mol
