Sodium bicarbonate and acetic acid are not good substitute for sodium azide in airbags since the require more mass and produce less gas.
<h3>Which is the better chemical for an airbag?</h3>
The chemical equation for the production of nitrogen gas from sodium azide is given below:
1 mole or 66 go of sodium azide produces 3 moles or 67.2 L of nitrogen gas.
The equation for the production of carbon dioxide from sodium bicarbonate and acetic acid is given below:
- Na₂CO₃ + CH₃COOH → CH₃COONa + CO₂ + H₂O
1 mole, 106 g of Na₂CO₃ and 1 mole, 82 g of CH₃COOH are required to produce 1 mole or 22.4 L of CO₂.
The mass of sodium azide required is less than that of sodium bicarbonate and acetic acid required. Also, sodium azide produces a greater volume of gas. Therefore, sodium bicarbonate and acetic acid are not good substitute for sodium azide in airbags.
In conclusion, sodium azide is a better choice in airbags.

sorry what us this i don't get it
From the equation it is evident that 2 moles of Sodium metal produces 1 mole of hydrogen gas.
At STP 1mole of any gas occupies a volume of 22.4 liters.
Therefore, 7.80 gives---(7.80×1)/22.4 moles= 0.3482 moles
Since the mole ratio of Sodium to hydrogen is 2:1, then the number of moles of sodium that reacted is given by the following expression.
(0.3482×2)/1 moles which gives 0.6964 moles.
The atomic mass of sodium is 23 thus the mass of sodium that reacted is given by:
mass=no. of moles×RAM
0.6964×23= 16.02 grams.
Compare the wavelengths of infrared waves, ultraviolet rays, and visible light. ... UV rays have shorterwavelengths and higher frequencies than visible light waves do.
