What is the compound for NaN3?
NaN3
Sodium azide/Formula
What happens when NaN3 is heated?
Sodium Azide, NaN3, mol wt 65.02, CAS Number 26628-22-8, is a colorless, odorless, crystalline solid (salt-like) or solution. When it is heated from 275 to 330 degree Celsius in dry air, the solid crystals will violently decompose into nitrogen gas, leaving a residue of sodium oxide.
What is the decomposition of sodium azide?
Automotive air bags inflate when a sample of sodium azide, NaN3, is very rapidly decomposed via the following reaction 2NaN3(s)→2Na(s)+3N2(g) 2 NaN 3 ( s ) → 2 Na ( s ) + 3 N 2 ( g ) . What mass of sodium azide is required to produce 2.6 ft3 (73.6 L) of nitrogen gas with a density of 1.25 g/L?
What is NaN3 used for?
Sodium azide is best known as the chemical found in automobile airbags. An electrical charge triggered by automobile impact causes sodium azide to explode and convert to nitrogen gas inside the airbag. Sodium azide is used as a chemical preservative in hospitals and laboratories.

Is HN3 a strong acid?
Hydrazoic Acid ( HN3) is a weak acid: a) write the equilibrium equation for the dissociation of HN3 b) calculate the percent dissociation of a 0.0400 M solution of HN3.
Is sodium azide flammable?
Sodium azide is combustible. The agent may burn, but it does not ignite readily. Fire may produce irritating, corrosive, and/or toxic gases. The agent may be transported in a molten form.
What happens when BA n3 2 is heated?
It can also be used as a source for high pure nitrogen by heating: Ba(N3)2 → Ba + 3N. This reaction liberates metallic barium, which is used as a getter in vacuum applications.
What is the balanced equation for the decomposition of sodium azide?
The heat generated causes sodium azide to decompose into sodium metal and nitrogen gas, which inflates the car’s air bags. Under normal circumstances, this molecule is quite stable. If heated, though, it will fall apart. The chemical equation 2 NaN3 –> 2 Na + 3 N2 describes exactly how it falls apart.
How is nan3 formed?
2 NaN3 → 2 Na + 3 N. The same reaction occurs upon heating the salt to approximately 300 °C. The sodium that is formed is a potential hazard alone and, in automobile airbags, it is converted by reaction with other ingredients, such as potassium nitrate and silica.
Is nano3 soluble or insoluble in water?
