Yes.
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.
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.
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....."
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.
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 :)
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.
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.
The gas produced by the burning of fuel is carbon dioxide.
When you combine magnesium dioxide with a burning wood splint in a gas generating bottle, the magnesium dioxide undergoes a chemical reaction in which it decomposes to form magnesium oxide and oxygen gas. The burning wood splint acts as a source of heat to initiate the reaction. The oxygen gas produced can be collected in the gas generating bottle.
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
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.
