How does sodium azide, used in air-bags, decompose?

Answer 1

#"Natrium azide"# decomposes according..........

#"Natrium azide"# decomposes according to the following stoichiometric equation:

#NaN_3(s) rarr Na(s) + 3/2N_2(g)uarr#

Given the stoichiometry, #"1.5 equiv"# of dinitrogen gas are evolved per #"equiv"# of the azide. We had #1.50*mol# azide, hence, #1.5xx1.5*mol=2.25*mol# #"dinitrogen gas"#. This is certainly enuff gas to fill an airbag under standard conditions, and hopefully prevent your nut from hitting the dash. Under standard conditions of #1*atm#, and #298*K#, what volume would this gas occupy?

Sodium azide used in airbags decomposes through a rapid exothermic reaction when triggered by a collision. It decomposes into sodium metal and nitrogen gas according to the equation:

2NaN3(s) -> 2Na(s) + 3N2(g)

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
