Use the reaction below for the decomposition of sodium azide to sodium metal and nitrogen gas.
2NaN3 (s) → 2Na(s) + 3N2(8)
What volume of nitrogen at STP is generated by the
decomposition of 130.0 g NaN3 ?

All of the following are part of the biosphere except

An electron moved from shell n = 2 to shell n = 1. what most likely happened during the transition? a fraction of a photon was added. a photon of energy was absorbed. a fraction of a photon was removed. a photon of energy was released.

3. how much energy in joules is required to evaporate .0005 kg of liquid ammonia to vapor at the same temperature? 4. how much energy ( in megajoules ) is given up by .75 kg of water at 0c when it freezes to form ice at 0c? 5. explain how heat works between and at critical temperatures?
