Question
Despite being a noble gas, Helium is not used in airbags. Explain.
▶️Answer/Explanation
Helium is not used in airbags because it is chemically inert and does not readily react with other substances. Airbags rely on the rapid generation of nitrogen gas to inflate, and helium lacks the chemical reactivity required for this purpose.
Question:
