Answer
Experiment : Take a jar filled with hydrogen with inverted mouth downwards and introduce a burning candle near the mouth of jar.
Observation : The gas burns at the mouth of the jar while the burning candle is extinguished when pushed inside the jar.
Conclusion :
- Hydrogen is combustible & hence burns at the mouth of the jar.
- It does not support combustion and extinguishes a burning candle when pushed inside.
