PLEASE HELP MEEE which statement describes a chemical change that occurs when a car's airbag inflates? A. the sodium azide melts into a liquid and increases in volume. B. the sodium azide mixes in the air, forming a solution of gases. C. the sodium azide gets so hot that it changes into a gas. D. the sodium azide breaks down into sodium and nitrogen gas.

The correct statement is D (the sodium azide breaks down into sodium and nitrogen gas).

Explanation:

A chemical change is an irreversible chemical reaction in which new substances are usually formed. It is also defined as chemical decomposition of a substance leading formation of two or more other substances. A typical example is in the break down or decomposition of sodium azide into sodium metal and nitrogen gas. This is seen in the chemical balanced equation below:

2 NaN3 --> 2 Na + 3 N2

Sodium azide ( also called Sodium trinitride) is a chemical compound that is in built into automobile air bags which upon collision is being triggered to decompose. This leads to the generation of sodium and nitrogen gas that fills the air bag. This aid ls in reducing the impact of the collision and absorbs the forward-moving energy of the occupant.

the bal will not change its velocity.

your answer is c! hope this : )
