Question

Determine the heat of the following reaction:
$F e O (s) + {F e}_{2} O_{3} (s) ⟶ {F e}_{3} O_{4} (s)$
Given informations:
$2 F e (s) + O_{2} (g) ⟶ 2 F e O (s); Δ H^{o} = - 544 k J$
$4 F e (s) + 3 O_{2} (g) ⟶ 2 {F e}_{2} O_{; 3} (s); Δ H^{o} = - 1648.4 k J$
${F e}_{3} O_{4} (s) ⟶ 3 F e (s) + 2 O_{2} (g); Δ H^{o} = + 1118.4 k J$
