Solid sodium peroxide (Na2O2) reacts with liquid water yielding aqueous sodium hydroxide and oxygen gas.  How much heat is released when 250.0 L of oxygen gas is produced from the reaction of sodium peroxide and water if the reaction is carried out in an open container at 1.000 atm pressure and 25°C?
(Given:  ΔH°f[Na2O2(s)] = –510.9 kJ/mol; ΔH°f[NaOH(aq)] = –469.2 kJ/mol; ΔH°f[H2O(l)] = –285.8 kJ/mol)
◦ 141.7 kJ
◦ 1740 kJ
◦ 2900 kJ
◦ 3330 kJ
◦ 35,400 kJ
