What happens when a burning matchstick is brought near hydrogen gas?
INFERENCE- Metals react with acids and displaces hydrogen from the acids to produce hydrogen gas and metal salt. If a matchstick is brought near the mouth of the tube containing the product of the reaction then we hear a pop sound. It is this hydrogen gas that burns with a pop sound.
What happens when you put fire in hydrogen?
Hydrogen burns with a pale blue flame that is nearly invisible in daylight. The flame may appear yellow if there are impurities in the air like dust or sodium. A pure hydrogen flame will not produce smoke.
What happens to burning matchstick?
When a match burns, it undergoes a chemical change. Matches use sulfur, phosphate and a friction agent held together by a binding agent. With a match, heat ignites the phosphorous on the head of the match. The initial heat from burning phosphorous breaks down potassium chlorate in the match head, which releases oxygen.
What happens to a burning match stick when it is brought near near the mouth of the test tube in which NaOH and Zn react give a reason?
Bases such as sodium hydroxide (NaOH) liberate hydrogen gas when reacted with active metals such as zinc and burns with a pop sound when burning splinter is brought near it.
Does hydrogen explode or burn?
Hydrogen gas is very flammable and yields explosive mixtures with air and oxygen. The explosion of the mixture of hydrogen and oxygen is quite loud.
Does hydrogen put out fire?
Hydrogen is flammable, but oxygen is not. When hydrogen combines with oxygen the result is water, where the atoms of hydrogen and oxygen are linked together to make a molecule with entirely different properties. You can’t burn pure water, which is why we use it to put out fires instead of starting them.
What happened when you placed a lighted match near the mouth of the test tube?
Hydrogen ignites in air. If hydrogen is present in a test tube, a lighted splint held near its mouth ignites with a squeaky pop.
What do you observe when lighted match stick is brought near the mouth of the test tube containing hydrogen gas?
We observe that hydrogen bums at the mouth of test tube with blue flame and pop sound is heard.
Why does hydrogen explode with fire?
Hydrogen gas is very flammable. The heat given off by the candle provides the activation energy required for the reaction that produces water from hydrogen and oxygen. This reaction is highly exothermic, producing the prodigious explosion.
