Question

select the characteristics for helium gas as compared to argon. (select all that apply.) limited resource heavier than air more expensive less expensive readily available from the atmosphere inert lighter than air

Explanation:

• Limited resource: Helium is a non - renewable resource and is becoming limited due to its use in various applications. Argon is more abundant in the atmosphere.
• More expensive: Helium is more expensive than argon. This is partly due to its limited availability and the cost of extraction and purification processes.
• Lighter than air: Helium has a lower density than air, which is why it is used in balloons. Argon is denser than air.
• Inert: Both helium and argon are noble gases and are inert (chemically unreactive). But the question is about characteristics of helium as compared to argon. Since this is a common property of both (noble gases), but it is still a valid characteristic of helium.

Answer:

Limited resource, More expensive, Lighter than air, Inert
