The colourless gas that reignites a glowing splint is oxygen. When a glowing splint, which is a piece of wood or paper that has been smoldered and is not flaming, is introduced to oxygen, the increased concentration of this gas allows it to combust and reignite. This reaction is commonly demonstrated in experiments to showcase the properties of oxygen in supporting combustion.

What gas re lights a glowing splint?
OXYGEN RELIGHTS A GLOWING SPLINT Oxygen.
Oxygen gas will what a glowing splint?
Oxygen will rekindle or relight a glowing splint.
Is chlorine burns with a glowing splint?
Chlorine gas does not support combustion and will not cause a glowing splint to reignite. Instead, it can extinguish flames. When a glowing splint is introduced into a chlorine-rich environment, the splint may not glow at all, as chlorine is a toxic gas and does not provide the necessary conditions for combustion.
What is relights glowing splint?
A relights glowing splint is used in qualitative analysis to test for the presence of flammable gases. The splint is ignited and placed next to the gas being tested; if the gas is flammable, it will ignite the splint, indicating its presence.
If you collected the gas produced by the photosynthesizing leaves how would you check if it contained oxygen?
The test for oxygen is to insert a glowing splint into a test tube and see if it glows brighter or re-ignites.
How do you check the presence of oxygen gas in a test tube?
To check the presence of oxygen gas in a test tube, you can perform the glowing splint test. Simply insert a glowing splint into the test tube - if the splint reignites, it indicates the presence of oxygen gas.
Would a glowing splint placed into carbon dioxide gas glow more brightly or reignite?
Neither, because it dies out. See the answer to the question "what happens to a glowing splint....."
Describe what happens in a positive test for oxygen gas?
In a positive test for oxygen gas, a glowing splint inserted into a test tube of the gas will reignite, indicating the presence of oxygen. This is a characteristic test for the presence of oxygen, as the gas supports combustion.
Which gas will re light a glowing splint?
More or less pure oxygen relights a glowing splint, while air oxygen (20%) will not do so.
What would happen if you put a glowing splint in nitrogen?
The glowing splint would extinguish in nitrogen. Nitrogen gas is inert and does not support combustion.
When ammonium carbonate decomposes what would happen to a glowing splint in the presence of the gases that are evoled?
When ammonium carbonate decomposes, ammonia gas is released. If a glowing splint is introduced to the ammonia gas, the splint would extinguish due to the lack of oxygen in the gas. Ammonia gas does not support combustion.
What is a test to show that gas is oxygen?
One way to test for the presence of oxygen gas is to use a glowing splint test. If the gas is oxygen, the glowing splint will relight when introduced into the gas due to oxygen's ability to support combustion.
