Question 1

How much energy is evolved during the formation of 98.7 g of Fe according to the reaction below?

Fe2O3(s) + 2Al(s) → Al2O3(s) + 2Fe(s)DrH° = -852 kJ

◦ 482 kJ
◦ 753 kJ
◦ 1.51 × 103 kJ
◦ 241 kJ
◦ 4.20 × 103 kJ

Question 2

According to the following reaction, how much energy is required to decompose 55.0 kg of Fe3O4? The molar mass of Fe3O4 is 231.55 g mol-1.

Fe3O4(s) → 3Fe(s) + 2O2(g)DrH° = +1118 kJ

◦ 2.66 × 105 kJ
◦ 3.44 × 104 kJ
◦ 2.38 × 102 kJ
