collect gas from reaction with a test tube, then light spint and insert into the gas filled tube. if splint is extinguished immediately, then its CO2.
but limewater test is more reliable
A burning splint can be used to test for oxygen or carbon dioxide by observing the splint's reaction. If the splint is placed in a container with oxygen, it will reignite or burn more vigorously due to the increased availability of oxygen for combustion. In contrast, if the splint is placed in carbon dioxide, it will extinguish, as carbon dioxide does not support combustion. This simple test helps differentiate between the two gases based on their effects on a flame.
You stated that carbon dioxide and nitrogen are present, but you did not mention oxygen. Nothing burns without oxygen . . . If you expose limewater to carbon dioxide, it will get cloudy, but will not if you expose it to nitrogen.
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.
Omar can use a glowing splint to test for oxygen by placing it in the gas; if it reignites, oxygen is present. For hydrogen, he can use a lit splint, which will produce a 'pop' sound when exposed to the gas. To test for carbon dioxide, he can bubble the gas through limewater; if it turns cloudy, carbon dioxide is present. These simple tests will allow him to identify each gas effectively.
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.

the positive test for oxygen is very simple. all that needs to happen is a vile must be filled 1/4 with hydrogen peroxide and a glowing splint must be inserted in t the vile . the splint will reignite after it is inserted int the vile.
Carbon dioxide1. Turns lime water (calcium hydroxide) milky2. A lit splint introduced to a test tube containing carbon dioxide should go outHydrogenA lit splint introduced to a test tube of hydrogen should go out with a distinct "pop"
One common test for carbon dioxide is the limewater test. In this test, carbon dioxide is bubbled through limewater, which will turn cloudy in the presence of carbon dioxide due to the formation of calcium carbonate precipitate. This cloudiness indicates the presence of carbon dioxide.
Neither, because it dies out. See the answer to the question "what happens to a glowing splint....."
When a lighted splint is put near carbon dioxide, it will be extinguished because carbon dioxide does not support combustion. This is because carbon dioxide does not contain any free oxygen atoms needed for combustion to occur.

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.
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.
To test for carbon dioxide, you can bubble the gas through limewater. If carbon dioxide is present, the limewater will turn cloudy due to the formation of calcium carbonate. Another method is to use a pH indicator, like bromothymol blue, which will change color in the presence of carbon dioxide due to the formation of carbonic acid.
