9.
Scenario 2
The airbags in vehicles contain a mixture of NaN,, KNO, and SiO, When a car decelerates at a rapid
pace, an electrical signal goes to the gas generator inside the airbag, triggering a series of three
chemical reactions:
10NAN, 10NA + 15N,(g)
(6) N- OPNS O'
K,sio,
10NA + 2KNO
KO + Na,0 + Na + SiO,
These reactions produce gas (N,) to fill the airbag and convert sodium azide (NaN,), a highly toxic
substance, to alkaline silicate (K,SiO.).
The quantity of NaN, must be carefully calculated to ensure that the volume of gas is adequate to fill
the airbag firmly enough to protect the passenger but not overfill and cause the bag to explode. A
standard airbag needs 67 L of N, (g) to properly inflate.

Expert Solution

Step 1

According to the given balanced Chemical Reaction -

10NaN₃ + 16SiO₂ + 2KNO₃ ---> 16N₂ + 5Na₂SiO₃ + K₂SiO₃

At standard temperature and pressure (STP) , 16 moles of Nitrogen required 10 moles of sodium azide. At standard temperature and pressure,one mole of any gas occupy 22.4 L volume. Nitrogen will also occupy 22.4 L volume at standard temperature and pressure, temperature of 273 K and pressure of 1 atm.

For calculation of Number of moles of a gas ,we can use Following formula -

Moles of a gas = Given volume in Liter/volume occupy by one mole of gas at STP

Moles of a gas = Given volume in Liter/22.4

Step by step
