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.

What is a positive test for each of the following gases oxygen hydrogen carbon dioxide?
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.
What of these will show that a gas is carbon dioxide?
to see if a gas given off is carbon dioxide you can trap gas in a test tube light a splint and place in tube if flame goes out then it is Carbon Dioxide
What makes a burning splint go out?
Removing from an oxygenated environment. for example placing in a test tube of carbon dioxide
What happens when a lighted splint is put near carbon Dioxide?
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.
Describe a test for carbon dioxide?
1. Limewater. 2. Light a splint and if the gas goes out it is most probably CO2.

How do you test for carbon dioxide with a splint?
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
What are the tests for carbon dioxide and hydrogen?
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"
What makes a burning splint go out?
Removing from an oxygenated environment. for example placing in a test tube of carbon dioxide
Test for carbon dioxide?
Testing for carbon dioxide step wise:- 1.Invert a test tube so that the open end is facing down. 2.Release the gas you want to test from its container into the test tube. Keep the test tube inverted so that the gas does not escape. 3.Light a splint with matches or a lighter. Place the lit end of the splint in the test tube. The splint will immediately extinguish if carbon dioxide is present in the gas. 4.Place moist blue litmus paper in the test tube. The litmus paper will turn red if carbon dioxide is present in the gas. 5.Place moist universal indicator paper in the test tube. The universal indicator paper will turn orange if carbon dioxide is present in the gas.
What test would allow you to tell the difference between carbon dioxide and nitrogen why would the burning splint test not work?
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.
How do we test carbon dioxide?

What happens to the falme when th burning splint is put into the mouth of the test tube with the test tube of solid calcium carbonate in it and then heated?
The burning splint is extinguished by the carbon dioxide given off from the calcium carbonate. CaCO3 --heat--> CaO + CO2 ==================================================

Which gas is in the bubbles. how can you prove this?
Carbon Dioxide. You can prove it by collecting some of the gas in a test tube (the gas is heavier than air). Drop a lighted splint into the test tube, and the flame will be extinguished.
