Post lab questions KClO3 lab by nuhman10


									Post lab questions:
1. 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.

2. At 1 atmosphere and 25 oC, what would the volume of O2 be from the previous question?

3. Assuming that air is 21% O2 by volume, what volume of air would be needed to answer question 1?

4. Assuming all of the analogous reactions occur, why would lithium chlorate be a more practical choice
for the “chlorate candle” than either sodium or potassium chlorate?
