Potassium superoxide, KO2, reacts with carbon dioxide to form potassium carbonate and dioxygen as follows: 4KO2+ 2CO2 -> 2K2CO3 + 3O2. This reaction makes potassium superoxide useful in a self-contained breathing apparatus.
a) Given th balance chemical equaition above, what is the mole relationship between KO2 and O2?
b)If you started with 0.250 mole of KO2 and 0.250 moles of CO2, which is your limiting reagent?
c) If an apparatus contains 2.50g KO2, how many grams of O2 is produced?
