It will extinguish the flame, as it replaces the oxygen around the splint, which is an essential component of combustion. The splint may relight if placed in an oxygen rich environment.
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.
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.
To identify gases using a wooden splint and a flame, you can perform two tests: For hydrogen, introduce a lit wooden splint to the gas; if it produces a characteristic "pop" sound, hydrogen is present. For oxygen, place a glowing (but not burning) wooden splint into the gas; if it reignites, oxygen is confirmed. For carbon dioxide, passing the gas over a glowing splint will extinguish it, indicating the presence of carbon dioxide.
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.
Yes.
carbon dioxide
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.
Carbon dioxide (CO2) and nitrogen gas (N2) can extinguish a burning splint. These gases displace the oxygen in the air, which is necessary for combustion, and therefore extinguish the flame.
Yes, a burning splint will go out in carbon dioxide gas because carbon dioxide does not support combustion. When the concentration of oxygen is low, the splint will not have enough oxygen to sustain combustion and will be extinguished.
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.
Neither, because it dies out. See the answer to the question "what happens to a glowing splint....."
Helium is a group 8 element, and therefore a noble gas. It has no free electrons to bond to oxygen, therefore it won't oxidise or combust. So no, it won't. As a side note, you may hear of stars "burning" helium, but this Ian burning, its nuclear fission :)
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.
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.
Removing from an oxygenated environment. for example placing in a test tube of carbon dioxide
The burning splint is extinguished by the carbon dioxide given off from the calcium carbonate. CaCO3 --heat--> CaO + CO2 ==================================================
