Correct option is D
The correct answer is:(D). Helium
Explanation:
Helium is used to blow balloons because it is lighter than air and non-inflammable. Unlike hydrogen, which is also light but highly flammable, helium is a safe, inert gas that does not react with other elements, making it ideal for party balloons, weather balloons, and airships.
Information Booster:
- Helium is the second lightest gas after hydrogen.
- It is colorless, odorless, tasteless, and non-toxic.
- Helium is extracted from natural gas deposits.
- It is also used in MRI machines, cryogenics, and deep-sea diving.
Additional Information:
- Chlorine: A toxic and reactive gas, mainly used for water purification and disinfectants.
- Neon: A noble gas, but heavier than helium; used in neon lights.
- Oxygen: While essential for breathing, oxygen supports combustion, making it unsafe for balloons.
