1) If 1.63 g of sodium peroxide (Na2O2) react with water to produce sodium hydroxide and oxygen, how many liters of oxygen will be produced at 25.0 °C and 725 torr? 2 Na2O2(s) + 2 H2O(l) → 4 NaOH(aq) + O2(g) Liters of oxygen = 2) A gas occupies a volume of 5.87 L at 0.950 atm. At what pressure will the volume be 8.45 L? Pressure =

Sodium peroxide is often used in self-contained breathing devices such as those used in fire emergencies because it reacts with exhaled carbon dioxide to form sodium carbonate and oxygen gas: a. balance the equation ___ Na2O2(s) + _____ CO2 (g) ----> _____ Na2Co3 (s) + O2 (g) b. If you begin with 3.50 g of Na2O2, how many moles of Na2O2 is that? c. If you begin with 3.50 g of Na2O2, how many moles of )2 can be produced...
