Ignoring any side reactions and assuming the reaction occurs completely, how large (in kg) an oxygen candle (KClO3) would be needed to supply 8 people with enough oxygen for 24 hours on a small submarine? Although this depends on the size of the person and their respiration rate (activity), according to NASA, an average person needs about 0.84 kg of O2 per day. = 17.2 kg
At 1 atmosphere and 25 oC, what would the volume of O2 be from the previous question?
Assuming that air is 21% O2 by volume, what volume of air would be needed to answer question 2?
