Question

Подушка безопасности в автомобиле сделана из прочного полиамидного волокна и в сложенном виде занимает так мало места, что ее прячут в стойку рулевого колеса. Она наполняется газом благодаря высокоскоростной химической реакции. Укажите уравнение этой реакции 1 - 2H(2)O -> 2H(2) ^ + O(2)^2 - CH(4) +2O(2) -> СО(2) + 2H(2)O3 - N(2)H(4) -> N(2) ^ + 2H(2)^4 - 2NaN(3) -> 2Na + 3N(2) ^5 - SiH(4) + 2O(2) -> SiO(2) + 2H(2)O

Answer 2

The given reactions seem to be a mix of chemical equations involving different substances. None of them represent the actual reaction that occurs during the inflation of an automotive airbag.

The chemical reaction responsible for inflating an airbag involves the rapid decomposition of sodium azide (NaN3) to produce nitrogen gas (N2). This reaction is highly exothermic and generates a large volume of gas quickly, which inflates the airbag rapidly.

The correct equation for the inflation of an airbag is:

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

When the crash sensors in the car detect a collision, an electrical signal is sent to ignite a small amount of solid propellant that generates hot nitrogen gas, which inflates the airbag.

It's important to note that the chemical reaction occurs rapidly and safely due to the precise engineering and design of the airbag system, ensuring the protection of the occupants during a collision.
