Question

Determine enthalpy of formation for $H_{2} O_{2} (l),$ using the listed enthalpies of reactions:
$N_{2} H_{4} (l) + 2 H_{2} O_{2} (l) \to N_{2} (g) + 4 H_{2} O (l);$
$△_{r} H_{1}^{o} = - 818 k J / m o l$
$N_{2} H_{4} (l) + O_{2} (g) \to N_{2} (g) + 2 H_{2} O (l);$ $△_{r} H_{2}^{o} = - 622 k J / m o l$
$H_{2} (g) + \frac{1}{2} O_{2} (g) \to H_{2} O (l); △_{f} H_{3}^{o} = - 285 k J / m o l$
