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 with this reaction?
d. Using your answer in part b or c above, how many molecules of O2 are produced when 3.50 g of Na2O2 reacts?
e.Using your answer in part b or c above, ow much Na2CO3 (in grams) can be produced from 3.50 g of Na2O2?
