The easiest method is to collect it in an upturned test tube, and place a lighted splint into it. If it goes out, pops, etc. it's not O2. If it burns much brighter, it is.
Add Silver Nitrate to it and a white precipitate should form
Hydrogen makes a squeaky pop sound when it reacts with oxygen in the presence of a flame, producing water vapor. This reaction is characteristic of hydrogen gas and is often used as a test to confirm the presence of hydrogen.
The test used to measure how much oxygen is taken in with every heartbeat is called pulse oximetry. This test estimates the oxygen saturation levels in the blood by measuring the absorption of infrared light in pulsating blood.
One way to determine that a sample of a mystery gas is oxygen is to perform a combustion test. If the gas supports combustion, creating a flame when exposed to a flame, it is likely oxygen. Additionally, using a chemical reaction with hydrogen peroxide and a catalyst to produce oxygen gas can also confirm the presence of oxygen in the sample. Finally, utilizing a gas sensor or gas chromatography to analyze the composition of the gas would further confirm if it contains oxygen.
A positive test for an alkene is the addition of bromine water, which will turn from orange/red to colorless when it reacts with the alkene due to halogenation of the double bond. This test is used to confirm the presence of alkenes.
The western blot test
The cold agglutinins test is used to confirm the diagnosis of certain diseases that stimulate the body to produce cold agglutinins
Negative result. Take the Western Blot to confirm. A non reactive HIV test is a negative HIV test. There is no reason to confirm this with a Western Blot. Western Blots are only used to confirm a positive ELISA.
The Western blot test is used to confirm the results
Yes. Regardless of the birth control used, if it failed, you'll be producing a specific enzyme when you're pregnant, and a test will confirm it or discount it.

Not usually. A biopsy would sometimes be used to confirm, as well as further blood tests.
They test it. If it works, then they confirm that it's true. If it fails, then they confirm that it's false.

I think it is a Bunsen burner? Can someone please confirm!!
You can test the evolved gases in electrolysis of water by collecting the gases separately in test tubes placed over the anode and cathode. The gas collected at the anode is likely oxygen, while the gas collected at the cathode is likely hydrogen. You can confirm their identities by performing simple tests such as the re-ignition test for oxygen and the "pop" test for hydrogen.
