In a popular television series, the two characters use thermite to assist with breaking into a chemical storage facility because the reaction between aluminum and iron(III) oxide produces a tremendous amount of heat. If they began with 10.0 g of Al, how many kJ of heat would be released? 29. 2 Al(s) + Fe,O3(s) → Al,O;(s) + 2 Fe(s) AH = -852 kJ 158 kJ A) B) 236 kJ 472 kJ D) None of the above

Expert Solution
Step 1
The enthalpy change of the chemical reaction when two moles of Aluminium reacted completely is given as -852 kJ (negatove sign indicate energy is released).
Therefore to calculate the total energy released for 10.0 grams of Al, first of all calculate the moles of Aluminium constituted by10.0 g by using formula...
mole = mass / molar mass
where, molar mass of Al = 27.0 g/mol
