In the reaction of CO2 and sodium peroxide (Na2O2), sodium carbonate and oxygen gas are formed. 2Na2O2 + 2CO2 --> 2Na2CO3 + O2 This reaction is used in submarines and space vehicles to remove expired CO2 and to generate some O2 of the required for breathing. Assume that the volume of gases exchanged in the lungs equals 4.2 L/min , the content of CO2 expired air is 3.8 % CO2 by volume, and the gases are at 26 degree Celsius and 740mm Hg . If the CO2 and O2 in the above reaction are measured at the same temperature and pressure, 1. How many milliliters of O2 are produced per minute? 2. At what rate is the Na2O2 consumed, in grams per hour?
