Heating a wood splint is a chemical change. If this was done in something like a test tube, you will see many things occur that indicate this. First, you will see a werid kind of smoke, the splint turning into black stuff, and a really bad smell. Well the smoke is CO2 and the black stuff is ash from the burning.
Because there is a new substance being made and the identity of the original substance(your splint) has changed, the reaction is chemical.

What is a splint in Chemistry?
A splint is a flat piece of a soft wood, about 15 cm long and a few mm wide and about one mm thick. It's used in the UK to show the presence of oxygen from a chemical reaction. The splint is first lit and it burns bright in oxygen.
What happens to a glowing splint when it is lowered into a jar full of oxygen?
It rekindles (flames up) the glowing splint..
Oxygen gas will what a glowing splint?
Oxygen will rekindle or relight a glowing splint.
What is the thing called that lights a Bunsen burner in chemistry class?
The stick used to light a Bunsen burner is called a splint however you have to light the splint with a match

A glowing splint placed in a test tube causes a loud pop Is this chemical or physical change?
Its a chemical change because a gas is produced (which is one of the signs of chemical reaction)
What are characteristics are physical properties and which are chemical properties?
Chemical properties- properties that do change the chemical nature of matter.For example the heat of combustion, reactivity with water, PH, and electromotive force. Physical properties-properties that do not change the chemical nature of water. For example color, smell, freezing point, boilig point, melting point, infra red-spectrum, attraction(paramagnetic) or repulsion(diamagnetic) to magnets, opacity,viscosity and density.

What is the name of chemical test for oxygen?
The glowing splint test.
What chemical test would you do to test for hydrogen halide acids?
Light a splint. Hold it above a test tube with the unknown gas in it and if the splint goes out with a sqeaky pop then there is hydrogen.
What simple test might be undertaken to check if a chemical reaction produces oxygen?
glowing splint ... if it relights then the chemical reaction produces oxygen.

What is indicated when a flaming splint causes a pop?
This means that in the chemical reaction that occured, hydrogen (H2) gas was produced. The splint will make the popping noise because literally there is a small explosion occuring, and water vapor will form.
When do you use splint?
You light a splint and then light the bunson burnor with the fire on the splint.
Why does a splint go out with a reaction of sodium carbonate and HCL?
Sodium carbonate (Na2CO3) reacts with HCl by the following reatcion Na2CO3 + 2HCl --> 2NaCl + H2O + CO2 The CO2 displaces the oxygen needed to keep the splint burning.
What is the chemical test for oxygen and water?
put oxygen in a test tube put a glowing splint inside and it will have a squeaky pop sound
