By chemical analysis; also a candle burn in oxygen (or in a gas containing oxygen) but not in nitrogen, argon, carbon dioxide.
Oxygen is a gas.
Oxygen gas is made up of one substance = oxygen. So oxygen gas is not a compound
The product of nitrogen gas and oxygen gas is nitrogen dioxide (NO2) gas.
Oxygen is an element. At room temperature, molecular oxygen (O2) is a gas.
At 1000 degrees Celsius, oxygen exists in a gaseous state. Oxygen gas (O2) is a colorless and odorless gas at this temperature.
Practically all foods contain oxygen; and the first is of course water. Also the Earth atmosphere contain approx. 20 % oxygen as a gas.

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.
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.
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.
Oxygen is a gas.
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.
Oxygen IS a gas at normal temperatures and pressures
Yes, oxygen is a colourless gas.
No, but oxygen is most common as a gas.
Hydrogen gas is H2. Oxygen gas is O2.
oxygen gas is heavier than hydrogen gas
