Oxygen can be identified through various methods, one of the simplest being the glowing splint test. When a glowing splint (a wooden stick that has been extinguished) is placed in a sample of gas, if it reignites, the gas is likely oxygen. Additionally, oxygen can be detected using chemical tests, such as the reaction with hydrogen to form water or through its characteristic support of combustion.

Practically all foods contain oxygen; and the first is of course water. Also the Earth atmosphere contain approx. 20 % oxygen as a gas.
It is most likely oxygen, as plants produce oxygen through the process of photosynthesis. Oxygen is a byproduct of the reaction that occurs when plants convert carbon dioxide and sunlight into energy.
The color code for an oxygen cylinder is typically green. This color helps to easily identify and differentiate oxygen cylinders from other types of gas cylinders.

Oxygen
Oxygen has a lower first ionization energy compared to nitrogen and fluorine because oxygen has a larger atomic size and a weaker effective nuclear charge, making it easier to remove an electron from an oxygen atom.
The number 8 above the element symbol O on the periodic table represents its atomic number, which indicates the number of protons in an oxygen atom's nucleus. This helps identify the element as oxygen specifically among the other elements.
Omar can use a glowing splint to test for oxygen by placing it in the gas; if it reignites, oxygen is present. For hydrogen, he can use a lit splint, which will produce a 'pop' sound when exposed to the gas. To test for carbon dioxide, he can bubble the gas through limewater; if it turns cloudy, carbon dioxide is present. These simple tests will allow him to identify each gas effectively.
