Sodium peroxide (na2o2) is used to remove carbon dioxide from (and add oxygen to) the air supply in spacecrafts. it works by reacting with co2 in the air to produce sodium carbonate (na2co3) and o2. 2 na2o2(s) + 2 co2(g) → 2 na2co3(s) + o2(g) what volume (in liters) of co2 can be consumed at stp by 435 g na2o2?

Over the last 90 years, scientists have added to the body of evidence supporting the big bang theory. what is the latest piece of evidence discovered in 2014?

How do cfcs cause ozone depletion? how do cfcs cause ozone depletion? ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule.
