Part a
in an automobile collision, sodium azide, nan3, decomposes and fills an air bag with nitrogen gas. if an air bag contains 1400 g of nan, (6501 g/mol),
what is the volume of nitrogen gas produced at stp? the equation for the reaction is
2nan; (s)
2na(s) + 3n2(g)

What are the first two quantum numbers for the electrons located in subshell 4d? what are the first three quantum numbers for the electrons located in subshell 2s? how many electrons can be held in a sublevel l = 3? how many electrons can be held in the energy level n = 4? how many electrons in an atom can share the quantum numbers n = 4 and l = 3?
