a glowing splint flares up in a gas jar of oxygen but not in air,why
Answers
Explanation:
A Burning Splint. Oxygen comprises about 20% of the air we breathe (and even the air we don't breathe). At this concentration, many things react with oxygen in combustion reactions, often releasing heat and light energy. ... In the presence of pure oxygen, wood burns even more quickly.
Answer:
Reason;
Oxygen gas relighting a glowing splint. ... When the glowing splint is introduced to the test tube, it bursts back into flame when it contacts the oxygen. Oxygen is the gas in the air that is responsible for maintaining combustion, which is a form of oxidation reaction.
The glowing splint test is a test for an oxidising gas, such as oxygen. In this test, a splint is lit, allowed to burn for a few seconds, then blown out by mouth or by shaking. ... Upon exposure to concentrated oxygen gas, the glowing ember flares, and re-ignites to produce a sustained flame.
