The CO2 evolved from the reaction extinguishes the flame.
A burning wooden splint has a visible flame at its burning end while a glowing wooden splint has glowing ember at its glowing end. Placing a glowing splint in a container with oxygen will cause it to burst into flames and become a burning splint.
The burning splint test for manganese involves observing a pale green flame when a burning splint is brought close to a manganese sample in a Bunsen burner flame. This test is indicative of the presence of manganese.
To do the burning splint test, you light a wooden splint and then blow it out to create an ember. You then place the splint near a gas sample without touching it. If the gas is flammable, it will ignite and produce a flame when the ember from the splint comes into contact with it.
You can't express that reaction because there isn't one: as CO2 is a well-known fire extinguishing agent, if you put a burning splint in CO2 the splint will go out. And the reason it will go out is CO2 displaces oxygen, which splints need to burn.
If the burning splint is extinguished upon entry into the beaker, one could conclude that the gas in the beaker is likely non-flammable or oxygen-depleted. If the splint continues burning, this suggests the presence of oxygen in the beaker.
hydrogen
Yes.
carbon dioxide
The gas that causes a burning splint to go out is carbon dioxide. Its presence is often used to test for the presence of this particular gas.
When lime-water is mixed with hydrogen and a burning splint is introduced, the mixture will produce a squeaky pop sound. This indicates the presence of hydrogen gas, as it reacts with oxygen in the air to create a small explosion. Lime-water itself does not react with hydrogen gas in this scenario.
It will go out. Nitrogen, which makes up 79% of the Earth's atmosphere, does not support combustion.
the lighted splint would stop burning as Helium does not burn.
