.. then the flame or glow will distinguish by lack of oxygen.
It is extinguished
You would put your thumb over the test tube it keep it contained then you would get a match or source of fire remove your thumb and put it over the test tube and if it popped or made a flame for a quick second it meant it was hydrogen always wear goggles when you do this experiment.
its particles freeze to make it solid
it goes out A glowing splint needs oxygen to basically keep glowing. It is a small fire in a way. When the glowing splint is added into an environment full of carbon dioxide, the splint goes out. Carbon dioxide in this case smothers the flame restricting the use of oxygen in combustion thus putting the flame out.
The liquid nitrogen has enough coldness to completely cool down lava, but also it has the exact same energy to make lava explode. Think of it as pouring liquid nitrogen on your hand, but if you don't put the right amount of heat (helium) and at the right time your your hand will fall off. Think of your hand falling off as explosion.
The glow of the splint is extinguished, because helium can not support the combustion reaction with oxygen from the atmosphere that produces the glow.
the lighted splint would stop burning as Helium does not burn.
Nitrogen, A splint needs oxygen, Nitrogen has none. Doesnt affect Limewater as far as im aware, that's Carbon Dioxide. Hope this helps!
Yes it does it makes it have a skueaky POP .
It is extinguished
The splint test is to test for the presence of oxygen. You light a small piece of wood (the splint), then blow it out. The end of the wood will still glow. If you put the glowing splint into a test tube with oxygen, it will relight. It you put the glowing splint into a test tube with carbon dioxide, it will stop glowing. A better test for carbon dioxide is to bubble it through a solution of limewater.
Insert a lighted splint into the reaction test tube. If it extinguishes with a "pop" sound, Hydrogen is present. The duller the pop the purer the hydrogen is.---------------------------------------------------------------------------------------------P.S. that's a burning splint.
The fire will be extinguished. The better test for identifying carbon dioxide is to bubble the gas into lime water. Limewater will go cloudy because of chalk/limestone precipitation.
If a lighted splint is put near of a mouth of a test tube containing hydrogen gas squeaky pop sound is heard.
a glowing splint in hydrogen gas will make a popping sound. this is because hydrogen is very reactive and when it comes into contact with the oxygen in the air it reacts with it and that is what you hear in the popping sound.
It explodes, making a "squeaky pop."
