Question

this passage describes a chemical reaction. read the passage. then, answer the question below. engineers test the safety of a new car by running a crash test, which shows whether the airbags inflate properly. when the car detects a crash, a small amount of sodium azide (nan₃) stored behind each airbag is heated. the sodium azide breaks down into sodium metal (na) and nitrogen gas (n₂). the nitrogen gas inflates the airbags in less than one - tenth of a second! this design helps to keep people inside cars from getting seriously injured in a crash. in the chemical reaction described in the passage, which of the following are products? select all that apply. sodium (na) nitrogen (n₂) sodium azide (nan₃)

Explanation:

In a chemical reaction, products are the substances formed from the reactants. The passage states sodium azide ($NaN_3$) breaks down into sodium metal ($Na$) and nitrogen gas ($N_2$). So $NaN_3$ is the reactant, while $Na$ and $N_2$ are products. The original selection incorrectly marked $NaN_3$ as a product; it should be unselected, and $Na$ and $N_2$ remain selected.

Answer:

• sodium (Na) (selected)
• nitrogen ($N_2$) (selected)
• sodium azide ($NaN_3$) (unselected)
