What happens to a glowing splint in the presence of oxygen?
A glowing splint will reignite in the presence of oxygen due to the process of combustion. Oxygen feeds the combustion reaction, allowing the splint to continue burning.
How could a burning splint be used to tell if gas were oxygen or carbon dioxide?
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.
What is the conclusion of the properties of gas in a beaker based on the behavior of the burning splint?
When a burning splint is inserted into a beaker containing gas, its behavior indicates the nature of the gas present. If the splint extinguishes, the gas may be inert or lacking in oxygen. If the splint reignites or burns more brightly, it suggests that the gas is rich in oxygen or a flammable substance like hydrogen. Thus, the splint's reaction helps identify the gas's properties related to combustion.
How do you do the burning splint test?
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.
What happens when a lighted splint is put unto a glass jar of helium?
When a lighted splint is put into a glass jar of helium, the splint will immediately extinguish because helium is an inert gas that does not support combustion. The lack of oxygen in the helium prevents the splint from continuing to burn.
What is the difference between a burning wooden splint and a glowing wooden splint?
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.
In the test tube which gas 'pops' when a burning splint is inserted?
Oxygen gas will "pop" when a burning splint is inserted into a test tube, due to the rapid combustion reaction that occurs between the oxygen and the flammable material on the splint. This reaction creates a small explosion sound known as a "pop".
What happens to a glowing splint in the presence of oxygen?
A glowing splint will reignite in the presence of oxygen due to the process of combustion. Oxygen feeds the combustion reaction, allowing the splint to continue burning.
What gas is produced when Sodium metal reacts violently with water to produce sodium hydroxide and a gas that pops in the presence of a burning splint?
The gas produced is hydrogen gas (H2). The reaction between sodium metal and water is a highly exothermic reaction that liberates hydrogen gas, which in turn reacts explosively with oxygen in the air when ignited by a burning splint.
Why does a mixture of vinegar and baking soda blow out a burning splint?
The CO2 evolved from the reaction extinguishes the flame.

What happens when you combine magnesium dioxide and a burning wood splint in a gas generating bottle?
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.

What is the result burning splint test for manganese?
The burning splint test for manganese involves observing a pale green flame when a burning splint is brought close to a manganese sample in a Bunsen burner flame. This test is indicative of the presence of manganese.
How do you do the burning splint test?
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.

When a lighted splint is put into a glass jar of helium, the splint will immediately extinguish because helium is an inert gas that does not support combustion. The lack of oxygen in the helium prevents the splint from continuing to burn.
What do you conclude about one of the properties of the gas in the beaker based on the behavior of the burning splint?
If the burning splint is extinguished upon entry into the beaker, one could conclude that the gas in the beaker is likely non-flammable or oxygen-depleted. If the splint continues burning, this suggests the presence of oxygen in the beaker.
