Why a candle brought near the mouth of a jar containing hydrogen gas starts burning but is extinguished when pushed inside the jar?
When the candle is brought near the mouth of the jar containing hydrogen gas, the hydrogen gas reacts with oxygen in the air to produce water vapor and heat, allowing the candle to burn. However, when the candle is pushed inside the jar, the available oxygen is quickly used up by the candle flame, leading to oxygen depletion and eventual extinguishment of the flame.

What happens when a burning matchstick is brought near the mouth of test tube in which a metal has reacted with sulfuric acid?
If a burning matchstick is brought near the mouth of a test tube in which a metal has reacted with sulfuric acid, the hydrogen gas produced from the reaction may ignite and cause a small pop or flame. This is because hydrogen gas is flammable and may combust when in contact with an ignition source like a burning matchstick.
When a burning candle is covered with a glass it get extinguished why?
When a burning candle is covered with a glass, the oxygen within the covered space gets depleted as the flame consumes the available oxygen. Without sufficient oxygen, the candle flame is unable to sustain combustion and gets extinguished.

What is the test for hydrogen gas?
if a burning splint is brought into contact with hydrogen gas a squeaky pop sound will be produced this would prove that hydrogen is present as hydrogen is extremely flamable.
Why does a lighted match stick put out when brought near a jar containing hydrogen?
A match won't light in hydrogen. It needs some oxygen.If you light a match in a mixture of hydrogen and oxygen, you'll ignite the hydrogen ...which also wants very much to burn in oxygen. The hydrogen will combine (burn) withthe oxygen instantly, brightly, and possibly loudly. The product that remains after thehydrogen finishes burning is H2O .
Why does a burning candle get extinguished when covered with a tumbler?
Fire needs oxygen to burn and when the tumbler covers the fire it uses up all the oxygen in the little space quickly and is extinguished.
Does hydrogen support burning?
Hydrogen does not support burning, instead it completely burns.

Do you have to burn hydrogen to make water?
No. Burning any flammable, hydrogen-containing compound will produce water, though there will be other products as well. You can also produce water through acid-base reactions and the decomposition of carbohydrates.
How does burning hydrogen not pollute the atmosphere?
Burning hydrogen involves using heat to start combustion of hydrogen which oxidises hydrogen. The same goes for burning carbohydrates (metabolism). Oxidising hydrogen gives us H2O and, well, water isn't a pollutant.
