Sodium azide (NaN3) can decompose at 300 o
C to produce sodium metal (Na) and nitrogen gas (N2).
This is one of the key reactions in an automobile air bag. The
balanced equation for this reaction is:
2NaN3(s) →2Na (s) + 3 N2(g)
Part A
If 0.189 mol mole of NaN3 is completely decomposed at
300.0 o C and 1.00 atm, what volume (in L)
of nitrogen gas would be produced?

1. Why metals or their compounds (like metal oxides, metal
hydroxides, metal complexes, etc.) that are strong chemical
reactants are not generally good catalysts?
2. Briefly describe why study of mechanisms of the absorption
and desorption processes helps us understand catalysis.

How to
design an experiment
In a lab, you
will have access to a mystery metal, a string, a retort stand, a
beaker, a kettle, water, two thermometers, a stopwatch, a weight
scale, and an insulated container with cup and lid. The metal can
be submerged in the container of water such that the water provides
a temperature bath for the metal. Design determine the
specific heat capacity of the mystery metal. In your preparatory
assignment: brass an experiment that...
